Modern day developments in the medical field have made treatments for many illnesses and diseases easier and safer to carry out. These advances have made a significant difference especially in the field of eye surgery. All surgeries are delicate procedures, however eye surgeries in particular need a great deal of expertise and precise treatment.
Involving the correction of minute cells and tissues, the equipment used in these procedures need to be state-of-the-art. LASIK treatment, PRK and LASEK are some of the treatments in the forefront of vision treatment and correction.
LASIK treatment during it's injection performed surgeries through the aid of a blade. The blade method although effective to some estimated was risky and took longer to heal as well as resolved in other complications. Some clinics offering LASIK treatment still offer this as an option. However, the discovery of the laser made a revolutionary change in this field. This means far more precipitate results, ease of surgery and a reduction in possible post-surgery complications. The laser option for LASIK treatment spread like wildfire spurred on by its comparatively more positive hits as opposed to its predecessor the blade.
There are a variety of different lasers that are used in LASIK treatment. In general, these are known as excimer lasers and are widely used to correct abnormalities in the corneal tissue. To be accurate, they remove problematic tissues in the stromal layer which is the underlay layer in the cornea. Vision correction for issues such as myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism is dependent on LASIK treatment which in turn uses the excimer laser for accurate medical attention. There are several different types of lasers available on the market, and which one is used depends on the surgeon as well as the clinic and how up-to-date they are with the current equipment in the industry.
As each person is different, the same laser may not suit everyone for LASIK treatment. The decision of which laser is suitable for you is made for your surgeon. However, for the sake of information it is good to get to know the different types of lasers. These are:
Spot scanning lasers: Also known as 'flying spot' lasers, these lasers are the most common in LASIK treatment. As they have small diameter beams, treatments done with the use of these lasers are known to be highly effective in accuracy and is popular for treating astigmatism.
Slit-scanning lasers: This laser is tricky to use and can be dangerous in the hands of an inexperienced surgeon. These lasers are linked to a device with holes that enlarge and it is through these laser that does its work. However, there is the risk of overcorrection.
Wavefront-guided lasers: Lasers can be divided into spot and slit lasers. Most are connected to a device that is able to map the eye and identify the problem area. As each person's issue is different to each other however minute, they are able to detect refraction of light in the eye.Spot and slit treatments are both possible in the wavefront method.
You will need to have an initial consultation to firstly determine your eligibility for LASIK treatment, and if put through to discus your options and which method is suitable to you. Having your research done beforehand can greatly help in understanding everything in the procedure.
