Laser Eye Surgery Problems You Can Expect

If you plan on getting laser eye surgery, you should also plan on handling the laser eye surgery problems that follow. These problems vary from person to person but often produce similar symptoms, despite differences in laser surgery technique. This article will help point out some of the complications you can expect after a typical laser surgery.

The most commonly reported laser eye surgery problem is dry eyes. Those who already experience from this syndrome are often not suitable candidates for this type of surgery and are usually turned down. However, if the patient is persistent in wanting to get their eyes zapped, then the eye surgeon can prescribe them certain medications to ensure that the patient is producing a sufficient tear film in order to handle the laser's side effects. Otherwise, alternatives to eye surgery would be recommended, such as orthokeratology lenses.

However, dry eyes can still be a significant side effect for suitable laser eye surgery candidates. In most cases, these irritating symptoms, such as burning, itching and a sensation of the eye sticking to the eyelid are self-resolving and using eye drops regularly after the surgery can alleviate such symptoms. If the dry eye syndrome lasts for an unusually long time, say for more than 6 months, then it is likely to be a permanent side effect. This is a rare occurrence and to prevent such side effects from becoming permanent, it is highly recommended that one should stay in regular consultation with their doctor or eye surgeon, for as long as 6 months to a year after the initial surgery.

One of the many other laser eye surgery problems that a patient can experience is eye infection. This is much more common in LASIK surgery, rather than LASEK or PRK surgery where there is less physical intervention by the eye surgeon. Regardless of the actual technique, a patient should still be wary of potential eye infections that can occur, as the eye is undergoing the healing process. Precautions such as, not applying lotions or creams, not allow chemicals near your eyes, not exposing you eyes to water and definitely not rubbing your eyes will help prevent dangerous infections to your eyes.

Another complication that you can expect is a loss of vision over time. This may seem contradictory to the whole point of eye surgery, but this is due to the nature of the eye itself and how it heals. Since there was an act of physical change in the eye, which specifically affected its shape, your body will attempt to recover it back to its original shape. In the same way when you get a cut or a breeze, your body will attempt to recover that original tissue or skin. However, sometimes, your body heals too much and this ends up under correcting the effects of laser eye surgery, which leads to a loss of vision over time.

These are just some of the laser eye surgery problems that you can expect after laser surgery. As with all surgeries, it is a risk that you must be willing to take. Otherwise you will have to accept wearing glasses or contact lenses for the rest of your life.

Problems With Laser Eye Surgery

Not everyone is perfect and there are times when problems with laser eye surgery can occur. Most of the time, this can result in further irritation of the common side effects of eye surgery. However, less foster patients are left with permanent, debilitating side effects that often lead to lawsuits and even depression.

Laser eye surgery itself has branched out into many techniques, one of them being LASIK surgery. The problems associated with laser eye surgery can be due to the eye surgeons 'faults or the patients' eyes. The most characteristic complication of LASIK surgery is a flap complication, caused by the surgeon misplacing the flap back on the cornea. This can cause irregularities in vision, such as ghosting and double vision. The surgeon may have also cut the flap too deeply or burnt off too much stromal tissue during the actual procedure which can lead to keraectasia or bulging of the eye. This complication can only be treated with rigid gas permeable contact lenses or corneal implants designed to hold the cornea in place.

Another flap complication that could arise is diffuse lamellar keratitis (DLK). This is very rare as the eye surgeon is continuously adding antibiotics into the operated eye during the procedure but can still happen due to the instruments not being properly disinfected. DLK typically occurs under the flap and causes severe inflammation and vision loss if left uncontrolled. If you experience any kind of inflammation around the center of your eyes, then you should go back to the surgeon so that they can open up the flap to clean off any inflammatory cells, which will prevent further tissue damage.

Some other problems with laser eye surgery is sight regression or under correction. This is more applicable to those laser eye surgery candidates who have very high prescriptions. However, this problem can still occur when the surgeon has not ablated the cornea deep enough. I know of a PRK surgery case where a man with a fairly high script continued to complain of contrast vision problems, such as glare, halos and starburst and also had sensitivity to light. This meant that it was actually painful for him to look at the computer or TV screen, because of this increased sensitivity and also due to the fact that his eyes were still healing. However, the main complaint was that he did not notice any improvement in vision and said that his vision was still very blurry after the surgery, like if he was not wearing his contact lenses. This was very likely due to the surgeon not ablating the cornea deep enough and as such, he has experienced what surgeons call a myopic creep. This condition can be easily fixed with a follow up visit to the surgeon, which I am sure he did.

All in all, most of the common problems with laser eye surgery are self-limiting and with time, the eye will successfully heal itself. For some other patients, this may not be the case and regular contact with the doctor or surgeon can help monitor the progress of your eyes and whether or not any action needs to be taken to resolve certain complications.

How to Choose the Right Frame Type

Glasses frames come in different shapes and sizes and also different materials. These variations are not there purely to make the frames look different, there are practical considerations to take into account also. The makers of designer glasses not only have to make the frames look trendy and modern; they have to make sure they are practical enough to be used as eyeglasses. I will briefly look at the differences in this article.

Plastic frames are good for people that are sensitive to some of the metals used to make spectacle frames, such as nickel and steel. They can be light and made of different colors. These colors are part of the frame and can not flake off like painted metal frames can. Plastic frames hold the lenses in well so if the lenses are fitted correctly they wont fall out without you drop them or push them out. They can be very comfortable on the nose if they fit nicely across the bridge. They are however more difficult to adjust if they do not fit well straight away.

Metal frames can be made thinner than plastic frames so can produce different shapes and styles. Plastic frames have to have an amount of thickness to make them strong enough. Metal frames can also be painted, giving rise to many patterns that can but put on them. Large chunky metal frames tend to be heavy but metal frames can be made thin and light.

Titanium is a common material to make frames from as it is light and strong. It also has the advantage of being hypoallergenic. Its down side is that it is more expensive. It is also harder to adjust due to its strength.

Supra frames are those specs that have a rim on the top and a thin nylon cord at the bottom. These reduce weight and also make the glasses look more minimalistic; if that's what you're after. They do tend to hold the lenses very well also.

Rimless frames are very popular but also tend to be expensive. This is because of the labor involved in drilling the holes that the sides attach to. Rimless eyeglasses are very light and look very smart. They are more delicate and the lenses should be made from the tougher 1.6 material. They can work them loose if not handled correctly so you must look after them well. They typically have one of two types of fitting, either two prongs and plastic plugs or a nut and bolt design. I favor the plastic plugs as they can be more easily refitted when loose.

LASIK Eye Surgery Complications and How To Deal With Them

LASIK eye surgery will inevitably involve some form of risk or danger, as it permanently alters the eye. However, this applies equally to all kinds of surgery, not just eye surgeries, and a candidate should be aware of such complications and how to deal with them, rather than just dismiss this potentially liberating opportunity. This will article will explain what LASIK eye surgery complications you can expect and what how you should deal with these complications.

The most commonly reported side effect of LASIK eye surgery is dry eyes. Your symptoms can be that of painful, itchy, gritty eyes as well as a sensation of something in your eyes. The best remedy is to simply use the eye drops that you were given after the surgery, which should help lubricate your eyes and treat your dry eyes. If you still experience dry eyes 6 months after the initial surgery, then the odd ones are that it is permanent and there really is not anything you can do about it. Remember, eye surgery is a risk, and it is a risk that you have to be willing to take. Thankfully, the getting dry eyes for that long is quite rare as many precautions are taken by the surgeon to ensure that you are a suitable candidate for LASIK surgery and that you are producing a sufficient tear film.

The second most commonly reported LASIK eye surgery complication is the loss of night vision. This does not mean being blind at night but experiencing visual disturbances, such as haloes, starbursts and glare, which are accentuated at night that can impair your vision, especially when you're driving. You may also experience ghosting or double vision, which can be worsened at night as well. These symptoms should normally heal by themselves and practically gone over the course of a few months. Once again, if it is unusually persistent you should go back to your surgeon to get an enhancement surgery to address these symptoms.

A loss of contrast sensitivity can also be a caring LASIK eye surgery complication as it can make it harder to discriminate differences in shades and colors. This, in turn, can make it more difficult to read, watch TV or the movies clearly without having the mental irritation of knowing that something is not quite right with your vision.

Continued intensive research and testing, eye surgeons themselves are human and prone to mistakes which can lead to under or over correction of your eyes. Most of the times that it is over corrected, the eye surgeon has certainly done this in order to factor in possible sight regression. However, when it is under corrected, this is almost always a mistake because sight regression can make surgery a complete waste of money because you'll be back to where you started. This kind of mistake is not common and this is why you should regularly visit the doctor to monitor the progress of your vision.

The final LASIK eye surgery complication that I'd like to mention is sight regression. As previously mentioned, this can be due to under correction of the eye but sometimes, it could have due to the fact that your eyes heal more quickly than other people. In this specific case, you will want to wait until your vision has stabilized before undertaking further LASIK surgery in order to correct this regression in vision. This may be several months to a year, but once again, this is highly dependent on your eyes.

LASIK Corrective Eye Surgery

Laser eye surgery can provide a means for some people to see clearly without the burden of having to wear glasses or contact lenses. One of the most well known variants of this is LASIK corrective eye surgery. There have also been many rumors and horror stories that is causing more harm than good, but this is likely due to those who have not been so fortunately or those who did not properly plan things out. This article will detail what LASIK eye surgery is and what you can do to avoid becoming the next LASIK horror story.

First of all, LASIK (Laser Assisted in-Situ Keratomileusis) corrective eye surgery is a very well known procedure having been performed by many eye surgeons around the world. The actual method behind LASIK surgery is this:

1. A central portion of the outer eye is cut out into a flap

2. A laser is fired into the eye

3. The surgeon replays the flap back to its original location

Prior to the LASIK corrective eye surgery, the eye surgeon would apply a retainer like tool to hold your eyelids open. Then, the surgeon would instil some eye drops into your eye in order to numb eyes, to prevent your eyes from getting dry and to act as an antibiotic. Once this preparation is complete, the eye surgeon would then proceed to cut open the flap using a microkeratome. You should feel no pain during this step as the numbing drops should have already taken effect. At the very worst, you will feel a pressure being placed onto your eye. After this, the surgeon carefully opens the flap and at this point, your vision will become very blurry. The eye surgeon or the assistant will turn on the laser, which will reshape the outer surface of your eye. At this point, you will see flashing lights, or blurs, and you will hear a snapping sound. This is very fast and takes less than 1 minute to do. Once the laser eye surgery is complete, the surgeon will rewet, smoothen the eye and also replace the flap back onto the eye.

Through the LASIK corrective eye surgery, the eye surgeon will regularly add drops into your eyes so that you will not be uncomfortable. As a matter of fact, you should feel any physical discomfort through the surgery. Once that is all done, the surgeon will give you a plastic bandage to cover the activated eyes so that it is protected from infection, being rubbed by you and also to allow your eyes to heal.

You should not engage in any physical activity for at least 4 weeks after LASIK corrective eye surgery. You should not expose your eyes to water, like in hot tubs, swimming in pools, the beach, the spa and so on for 1 to 2 months after surgery. You should also not apply any kind of lotions or creams near your eyes for about 2 weeks after the surgery. All in all, you should continue to use medications given to you by doctor after the surgery and to regularly consult with your doctor to monitor the progress of your eyes and your vision. If the worst comes to worst, as in repeating symptoms of dry eyes, visual disturbances such as glare and sensitivity to light, or infections, you should go to your surgeon immediately to see if you can get an enhancement surgery or antibiotics to treat the infection .

How Safe Is Laser Eye Surgery Anyway?

Laser eye surgery has been tried and tested over its 23 years of existence. Over 36,000,000 LASIK procedures have been performed throughout the world, and nobody has lost an eye from having the procedure. The risk associated with laser eye surgery is less than that associated with contact lenses, and as far as infection goes, it represents a small one-time risk, as opposed to the ongoing risk of infection with contacts.

Laser eye surgery's safety has been experienced with and assessed by government and military organizations such as the US Navy, the Australian Army, and NASA. Their investigations show that blade-free LASIK (ie creating a corneal flap with a femtosecond laser) is safe and approved for the SAS, Top Gun pilots and NASA astronauts.

Professional sportspeople also have used laser eye surgery to ensure their best performance on the field. This includes sportspeople such as Tiger Woods and David Beckham, whose vision correction procedures unduly allows them to perform at their peak.

Despite having such an exceptional safety profile however, laser eye surgery is still surgery, and therefore will always have the potential for complications. Such complications are generally rare and always manageable though, which I will discuss below.

Enhancement:
LASIK surgery is performed on the eye, an organic tissue. Although the procedure is extremely accurate, there is an average 3-4% risk the correction will be decent but not absolutely optimal. In these cases, I usually wait around 3 months to ensure the stability of the residual glasses prescription, then lift the same corneal flap created earlier to “fine tune” the procedure's outcome. These enhancements are minor corrections, and are there before more accurate. A great advantage of laser eye surgery is that, although very stable in the long term, should anyone experience any refraction shift in their vision, improvements such as these can be at almost any time in the future.

Risk of infection:
As mentioned before, the rate of infection as a result of laser eye surgery procedures is extremely low, far less than infections resulting from contact lenses. Corneal scarring resulting from infection occurs even less than this, at a rate of less than 1 in 20,000. Even if this occurs, it is correctible with a corneal transplant. As a corneal subspecialist, I've performed a lot of corneal transplants, but have never had to perform one for this reason.

Corneal flap issues:
Blade LASIK introduced the risk of creating an abnormal flap (such as a buttonhole flap). However, blade-free (femtosecond laser) LASIK eliminates this risk altogether, and due to this enhanced safety, it is the only form of laser eye surgery I perform.

With blade-free laser eye surgery, inflammation under the flap can sometimes occur (this is called diffuse lamellar keratitis), and can be managed by an increase in anti-inflammatory eye drops. If cells on the cornea grow (epithelium – a very rare occurence), they will generally absorb and disappear. If they ever proliferate, the flap can be lifted and the offending cells removed.

Dry Eye:
Temporary dry eye phenomenon is created when the nerves of the cornea are cut, which occurs during laser eye surgery. It can take about 3 months for these nerves to regenerate. During this time I would advise replenishing the tear film with lubricating drops.

Ectasia:
Ectasia is quite a very rare occurrence in which laser vision correction causes the cornea to become too pliable, and therefore bulges forward over time. Extreme cases of ectasia have been corrected by corneal transplantation, although unfortunately pre-operative screening of patients has increased in accuracy, meaning candidates unsuitable for laser eye surgery are almost always identified before the procedure. Recent advances in the technique of collagen cross-linking also allows us to stop this rare complication from progressing further, and lets the patient maintain their vision while avoiding a cornea transplant. I am one of few eye surgeons in Australia who is experienced in this and can perform it in my surgery, however I have never needed to perform it on my own patients.

Glaring and Halos:
After the procedure, patients sometimes see starbursts or halos around lights in the night. This is most often due to the corneal flap dehydrating and stabilizing, and it is rare to see this phenomenon persist longer than about a week.

Quality of vision:
The majority of patients feel that their vision after laser eye surgery is better than their vision with glasses or contacts before the operation. There is always a very small minority who experience visual quality less crisp than their pre-operative vision, but this situation is generally rectified by laser enhancement.

Laser eye surgery's proven and maintained track record of safety, accuracy and efficiency make it the clear treatment for becoming independent from glasses or contact lenses. Recent advances in blade-free femtosecond LASIK takes this to new levels, and certainly represents the height of eye surgery and vision correction.

Top 5 Health and Safety Reasons Why You Should Wear Sunglasses

Sunglasses are now conspiratorial with high fashion. They can change your image and attitude with most of us from the western world owning a few pairs. Fashion side, wearing 100% UV protected sunglasses is key to your eyes health and safety.

1. Damaging UV Light – The Science Behind It All

On a sunny day the diameter of a pupil will be around 3 mm. When wearing dark lenses in sunglasses the pupil will increase dilation up to 4.5mm diameter. That's about 2.5 times more light reflected into your eyes, traveling through the pupil to your retina.

Thank goodness that wearing top end sunglasses with good lenses only a tenth as much light reaches your eyes and pupils. The light actually reaching the retina is diminished by a factor of around 4. Even though your pupil dilates when wearing sunglasses, if you're wearing the best quality then your eyes will still benefit from them.

2. UV Light is Harmful to Your Retina

If you're not wearing premium grade sunglass lens ultraviolet light can easily travel through a pair of sunglasses into your dilated pupils, extremely causing long-term damage to your retinas. Thinking about eye safety when purchasing a set of sunglasses is crucial, particularly if your wearing sports sunglasses for sporting events that expose your eyes to UV light for long periods of time.

3. Reducing Headaches and Eyestrain

Migraines, tension, and headaches can be brought on or exacerbated by direct sunlight. This can be caused by the pupils being diluted for a long time when exposed to intense UV rays. Cornea damage can be a side affect of long periods of sun exposure. Again, premium grade 100% UV rated lenses can greatly reduce these symptoms and alleviate headaches and may even prevent them.

4. Reducing 'Dry Eye' Syndrome for Comfort and Safety

Uncomfortable dry eyes is very annoying and at worst dangerous, especially when driving in high glare situations. Wearing sunglasses can repel some heat and direct sunlight and help keep eyes moist by reducing the evaporation of tears. The eyes need moisture to focus and perform correctly; This is why good quality sunglass lenses are key to eye comfort and safety.

5. Increasing Driver Safety by Reducing Road Glare

Driving in bright sunlight can be dangerous for the driver and their eyes. Ultraviolet light that is refracted off a road can be more intense than being outside of the car and requires good quality lenses, better polarized to help prevent distracting and dangerous road glare.

Research has shown that purchasing the premium quality sunglass lenses will give your eyes the best protection from the sun while increasing both your comfort and safety. Polarized lenses are common among sports sunglasses and also the safest choice when driving. With a large range of sunglass lenses available to buy sunglasses online is a practical option, even if you upgrade to polarized lenses to ensure you have the safeest option while driving. Always check that sunglass lenses meet US standards and block 100% of UV light.

Surprising Claims Prove Adults May Need a Contact Refresher Course

Contacts have become second nature to most lens-wearers, which is a gift to most and a curse to those in the eye care profession. After getting acquainted to the world of contact lenses, each person adopts a contact routine that works perfectly for them. The application steps and contact lens hygiene that used to be taken with precision and care are now an after thought in people's every day routines. A recent study by Bausch and Lomb, a large contact lens company, show that the patients may have become too relaxed when it comes to their contact lens hygiene routeine.

Two thousand adult contact wearers were surveyed on their contact routine and the results were unusual and surprising to say the least. Twenty percent of the lens-wearers reported that they use abnormal solutions from time to time if they are without contact solution. Abnormal is one thing but the list of replace solutions confirmed by the respondents, include household items including soda, fruit juices, butter, or anything else within reach in crisis time.

After such a study it is clear that after a while contact lens wearers become too lenient and undiscriminating when it comes to the hygiene of their contacts and most importantly the health of their eyes. The alternatives listed are harmful to the eye and will potentially denigrate the contacts themselves.

Aside from the unusual solution alternatives, the respondents reported that most are likely to use saliva or water lubricate or clean their contacts. These alternatives, may seem better than the above reported soda and butter but still carry huge risks of infections. The bacterial level in saliva is a breeding ground for infections; most infections that patients do not have treated until they are severe. Moreover, tap water and bottled water and may include microbes that can cause injury to the eye and have been linked with infections resistant to treatment, such as Acanthamoeba keratitis .

Contacts lens are a safe and viable substitute to glasses when used correctly. The purpose is to enhance vision and give patients options. To ensure that contacts are used safely, there are guidelines for hygiene and application. The most important piece to the puzzle is eye care; and unfortunately it may come second to convenience. Even as an adult, it is essential to refresh on contact lens hygiene and application practice to be a safe contact wearer.

To aid in crisis situations it is encouraged to keep a contact case near, along with small bottle of contact solution. Many patients may find it easy to keep spare items in their car, at work, at home, and anywhere in between. Some of the key contact tips are to: wash your hands before application, change contact case regularly, always use contact solution. Patients are welcome to make an appointment for a refresher course or watch this video to refresh at home.

Will I See Better After Laser Eye Treatment Than With My Eyeglasses?

Your optometrist will make sure that you have the clearest possible vision both at distance and up close when prescribing glasses. An autorefractor or retinoscope, phoropter, and trial frames will be used to appraise the eyes.

As with spectacles prescription, your ophthalmologist should also offer you the best possible vision with laser eye treatment.

Your sight, however, may not be as clear after surgery as compared with your spectacles.

There are times when your optometrist will not give you the prescription which gives you the clearest sight and there are a few reasons why this is so.

If your eyes have alternately dramatically compared to your previous eye exam and eyeglasses, a large change in your spectral prescription can cause dizziness, nausea, headaches, and anxiety. To alter your Rx, your optometrist may then lower it somewhere between your last and last prescription for ease at the expense of clarity. As a consequence, you may need to modify eyeglasses over and over again because this is just a temporary prescription to what you really should be wearing.

Modest changes in your astigmatism may not be included in your eyeglass Rx if your optometrist chooses to do so. Small variations in astigmatism do not really improve vision but can cause your new specs to be distressing.

If your glasses are for near work, a starting point for your optometrist would be to optimize your vision for a working distance of 40cm. This is the standard distance for reading. Should you be using your images for computer work, it should be modified properly to make the computer screen more comfortable as well.

When it comes to laser eye treatment, your ophthalmologist aims to completely rectify your sight, giving you the greatest clarity. An increasing prescription rather than changing your prescription to plano (no Rx) is the common cause of discomfort when using “new prescriptions” after having laser eye surgery.

You will also discover that after laser eye treatment, you still have unhampered peripheral vision. Unhindered peripheral sight can also be caused by a high Rx or small and thick-templed frames. Your peripheral sight will be the same with wearing contact lenses.

You may think this would indicate that your vision after laser eye treatment is better to your spectacle sight.

Regrettably, not everyone is contented with their vision after having laser eye surgery. Unfortunately, even if a lot of successful patients can see 20/20 after the surgery, this is not the situation for everyone.

Of those who do see 20/20, other optical factors can result in disappointments. One effect is glares and nighttime halos that happen when the pupils enlarge in the night, enlarging past the surgical area with the peripheral of the flap causing the optical symptoms.

Near sight may also not be fully corrected with presbyopia because eyeglasses may still be needed for reading even after the laser eye treatment. Because of today's technological advances like PresbyLasik, this is becoming less of a worry already.

It's always best to discuss with your local ophthalmologist or optometrist before proceeding with laser eye operation. They should be able to give you professional advice about the expected results based on the data they collected from your eye exams. With their guidance, you can make an informed judgment as to whether laser eye treatment is right for you or not.

Surgery Versus Anti-Ageing Creams: Weighing the Benefits

When you look at yourself in the mirror, do you still like what you see? If the answer is no, thenhaps you wanted to take an immediate course of action to cross the bridge between ageing painfully to aging gracefully. Now that you have the willpower to bloom younger and recount the days back to your youthful times, it is now time to assess the tons of possibilities that you can explore in order to come up with the best solution to your aging look. Now, the two most popular ways are surgery and anti-aging creams.

Most people are aware of the risks, discomfort, long recovery stages and of course, high cost that might be in for you when you succumb to surgery. Another thing to consider is the skills of the surgeon. Not all surgeons are equally skilled and have equal due to patient care during the process of surgery and the recuperation stage. Not to mention the discouraging looks of women we see on TV what faces looks like wax or fake or anything unsuitable for that matter. There have been cases of wrong administration of general anesthetic to the surgery itself which led women to be hospitalized and recovery stages dragging longer than they should be.

Moving on to anti-aging creams, the difficulty lies in the point of choosing which cream is the best for you. Considerations in choosing anti-aging cream are efficiency, immediacy and safety. Sure, there are a lot of brands out there, but how do you know if it is effective or not? But the good thing in this which most people actually overlook when it comes to effective anti-aging creams is that these creams are not only taking effect in your skin the moment you apply it, but its effects will also continue fighting skin aging as long as you are using it. Thus, investing in a very good set of anti-aging application products can be very practical and safe.

Putting these things together, it is safe to say that both surgery and anti-aging creams can provide you with a youthful skin, but the only question now is which method will provide you a young-looking skin longer? Surgeries are generally effective, but ant-aging cream does the same thing as well minus the high-expenses, and most importantly, the high risks and undesirable characteristics of surgery. And besides, there is no guarantee that you will come out from a surgery with a natural youthful skin. Unlike anti-aging creams which offer youthful skin in a non-invasive process, you get to improve your skin without compromising your health.

LASEK Vs LASIK Eye Surgery

There may be some of you out there who are more knowledgeable than others when it comes to laser eye surgery. Of course, there are many variations such as LASIK, LASEK, PRK, wavefront custom LASIK, epi-LASEK and much more but in reality, you can only choose one. Some potential candidates may want an alternative to LASIK eye surgery, due to the horror stories that they might have heard so may want some information on LASEK eye surgery instead. This article will help elucidate the differences between LASEK vs LASIK surgery.

LASIK (Laser Assisted in-Situ Keratomileusis) is a laser eye surgery where a flap of the outer eye is cut out by a blade known as a microkeratome. In some surgeries that you might have seen or heard about, it may look like a can opener, but this is simply a circular blade. In some other instances, a laser can be used for greater accuracy, but would result in a slightly more expensive procedure. In any case, this flap is cut out so that a laser can burn the inner layers of the eye. This reshapes the eye so that light rays can focus on one point on the retina, which results in a clear, undistorted image.

In an actual LASIK procedure, a sort of retainer like tool is placed onto the operated eye in order to hold the eyelids open. Afterwards, the surgeon squeezes some eye drops in, to numb the eyes prior to the surgery, to prevent the eyes from becoming dry and also to act as an antibiotic. The surgeon will then proceed to operate on the eye with the blade or laser, and then pull the flap away to use the laser on the inner layers of the eye. You will see see flashing lights which should last about 1 minute. After that, the surgeon will replace the flap back onto the eye. Through the whole procedure, the surgeon is continuously rewetting your eye with the drops and smoothing the outer surface of the eye. Because numbing drops were instilled into your eye, you should not feel pain through the entire procedure. The most intense sensation that you will ever feel is pressure on your eye when the surgeon is cutting the flap.

On the other hand, LASEK (Laser Assisted Epithelial Keratomileusis) is also a laser eye surgery very similar to LASIK. It is actually a variation of PRK surgery, but instead of direct laser energy, a flap of the most outer layer of the eye, known as the epithelium, is cut out. Prior to this, the eye surgeon would ordinarily add numbing drops to your eyes, followed by putting in the retainer to hold your eyelids open. The surgeon would then proceed to cut open the corneal epithelium and add an alcohol solution to your eyes in order to loosen the edges. Once it is adequately loosened, the eye surgeon would pull back the flap after which the laser would then be fired into the eye, just like in LASIK surgery. Once this is done, the surgeon would add eye drops to rewet then eye, smoothen the eye and then replace the epithelial flap back onto the eye.

To conclude, the debate of LASEK vs LASIK eye surgery all comes down to whether or not you are eligible to LASIK surgery in the first place. This is because LASEK surgery has quite a long recovery time, even longer than PRK, and often suggested as a second option if the patient is not eligible for LASIK eye surgery.

Eye Vision Nutrition – How It Can Help Clear Blurry Vision

Recently, there has been a lot of discussion about reversing blurry vision naturally. Can regaining 20/20 vision back with natural eye exercises really eye achieved?

New studies are now confirming a connection between what you eat in relation to how your eyes perform.

Increasing your physical activity and maintaining a well-balanced diet will indeed improve the quality of your life and help preserve and improve your eye sight.

Keep in mind, anything you do that affects your cardiovascular system has the potential to damage or repair your eyesight. This includes exercises and eye vision nutrition. Any change in blood supply to the eyes can cause blockage, resulting in blurry or loss of vision. Improper diet and lack of exercise has been the catalyst for many with Type 2 diabetes which can then lead to diabetic retinopathy and eyesight loss.

A balanced diet containing the 3 major sources of fuels are proteins, fats and carbohydrates. These are necessary to keep our bodies, minds and eyes healthy and strong. Omega 3 fatty acids in fish, low fat proteins in chicken and legumes, whole grains and plenty of fresh fruits and vegetables are necessary for optimal vision.

Proper eye vision nutrition requires adequate amount of micronutrients, 50-60% complex carbohydrates, 20-25% proteins, and 20-25% fats ideally containing omega-3 fatty acids.

To help improve bad vision, follow the diet recommendations below and incorporate simple eye exercises into your lifestyle. Also, consider taking vitamin supplements to insure that you are receiving good amounts of micronutrients that are important to maintaining eye health.

Bad Eye Vision Nutrition

Saturated Fat

Fatty Meats and Whole Dairy Products

Fast Foods which are high in trans-fatty acids

Snack Foods which are high in saturated fats

Soft Drinks diet or otherwise

Candy

High Amounts of refined Sugar

Good Eye Vision Nutrition

Plenty of Fruits And Vegetables – Organic is preferred

8 Large Glasses of Water Daily

Vitamin Supplements A, B, C and D

Lutein, Beta-Carotene, Bilberry Extract

Fruits and Vegetables

Polarized Motorcycle Sunglasses: The Pros and Cons

Polarized glasses have been around for decades, contrary to what many consumers believe. The first polarized glasses were sold in the 1930's, developed especially for pilots.

The technology changed the market, and today polarized lenses are used by all kinds of people. They're especially popular with outdoors enthusiasts and athletes. They are also growing increasingly trendy in motorcycle sunglasses.

The History of Polarized Glasses

Polarized glasses were first developed and invented for use in the military, specifically by pilots. Sunglasses themselves had only been on the market for a few years, but were well-received by consumers. Military pilots found them beneficial when flying in bright sunlight, with the exception of one problem: reflective glare.

When light from the sun travels through the atmosphere, it is dispersed evenly (polarized) when the light wave hits the retina. Reflected light, however, does not disperse (polarize) evenly.

Rather, it becomes horizontally polarized as it reaches the human eye. The result is a glare that is uncomfortable at best, and temporarily blinding at worst.

This temporary blindness can be fatal when piloting an aircraft. The Poloroid Corporation saw this problem as an opportunity to make money. They began working on polarization technology to solve the glare problem when flying.

The world's first polarized aviator shades were born in 1936 and distributed to military pilots. They became available for public sale the following year.

How Polarized Glasses Work

The lenses of polarized glasses of today are like ordinary lenses, with one extra component. A very thin film is placed inside each individual lens. This film is polarized so that when reflected light hits the lenses, it becomes dispersed more like regular light waves. This reduces glare from reflected light.

Naturally, this reduction in glare makes activities like flying an airplane or driving a car or motorcycle safer. It only takes a split second of temporary blindness to result in a fatal error or accident.

Polarized glasses revolutionized first the military and then the airline industry. Today it makes life easier and safer for all kinds of sports and outdoor lovers as well as drivers and cyclists.

What to Beware of When Wearing Polarized Motorcycle Sunglasses

As with any product, even a revolutionary one, polarized glasses have a few drawbacks. These must be considered carefully if you're thinking about purchasing motorcycle sunglasses with polarization film in the lenses.

When airplane instrument panels began to become digitized, pilots began noticing problems with their high-tech aviator shades. Their polarized glasses made it difficult to read their LCD displays. The same thing can happen to motorcycle drivers if they happen to have LCD displays on their bikes.

Another problem, though minor, is that of contrast between snow and shadows. Polarized glasses can sometimes make snow and shadows blend together. A motorcycle driver that mistakes snow on the road for a shadow could end up in a skid.

Of course, another potential problem is that a driver may tilt his head at too sharp an angle. This causes some horizontal light to enter the eyes over, under or through the sides of the frames and lenses. The result is bright spots that may pose a driving hazard.

Overall, it seems that the benefits of polarized motorcycle sunglasses outweigh the drawbacks. It may take cyclists some time to get used to wearing them.

It's suggested that motorcyclists start out by wearing them for short periods of time on short, low-speed trips. Bikers may also want to practice on back roads when they first start wearing polarized glasses. Doing so will give the rider time to adjust to some of these potential issues and compensate for them in regular, highway-speed driving.

Simple Treatments for Blepheritis

Blepheritis is a simple condition that affects a large number of people to varying degrees. It basically means inflammation of the eyelids. Sometimes the problem goes by unnoticed but at other times it causes significant discomfort. The symptoms range from mild redness and itching to very red, sore eyes. Some people feel they need prescription glasses when driving or watching the television to cure the problem. This is usually not the case.

The problem with Blepheritis is that it is incurable, you can only treat the symptoms, if you stop treatment, it usually comes back. It is often said that we can send a man to the moon but we cant cure Blepheritis.

It is usually caused by the natural bacteria that live in and around your eye lids, growing out of control. The natural chemistry in your eyes changes, for various reasons, encouraging excess bacterial growth. Your body responds with an inflammatory reaction causing warmth and irritation. Wearing or not wearing your eyeglasses makes no difference at all, although some people feel their glasses help hide the redness and puffiness.

There are various eye drops that may help, along with other products you can buy that may help. This article though will explain how to help in a very cost effective way.

The first thing to do is to get your meibomium glands working properly again. These glands secret the oily part of your tears and help prevent your eyes drying out. Often they become blocked and do not work properly.

You need to get a bowl of warm water, not hot enough to burn yourself, dip a clean flannel in the water and wring it out. Now hold the flannel over your eyes, remember to take your spectacles off! When the flannel cools, dip it back in the water, wring it out and hold it over your eyes again. Repeat this process for about 3-5 minutes. At this point your are just heating your lids up, the heat is melting the oil in these glands.

Next you need to gently massage your lids in a direction toward the eye opening. This means massaging from top to bottom of your upper lids and from bottom to top of your lower lids. Be careful to use the pads of your fingers and not to scratch your eyes with your finger nails.

You now need to clean your lids. Get a saucer of water mixed with a few drops of no tears baby shampoo. Dip in a piece of cotton wool and wipe along your lids. You need to try and clean the thin flat part of your eye. Not the inside or outside of the lids but the flat part just behind your lashes. At the same time make sure the roots of your lashes are cleaned as they often become very crusty.

Repeat this process 2-3 times a day for a month, and if your eyes feel better, reduce it to once every other day to keep on top of it.
