What is Lasik Eye Surgery?
Lasik eye surgery is one of the most common forms of surgeries to obtain clearer, sharper vision. The process includes rectifying certain vision issues, minimizing or eradicating the need of corrective lenses. LASIK as we understand is the short form for laser-assisted in-situ keratomileusis meaning surgical procedure. The surgery transforms the shape of the cornea. The desired outcome of a Lasik eye surgery is to bend light rays to focus specifically on the retina rather than some point other than retina.
Why is it required?
If you are suffering from the following vision problems, then Lasik surgery may be an option:
- Myopia: when your eyeball is a ted longer than usual or when the cornea curves sharply, light rays focus in front of the retina and affect distant vision. You can see objects that are close but find difficulty in seeing that are far.
- Hyperopia: When you have a shorter than normal eyeball, light tends to focus behind the retina resulting in distant and near objects blurry.
- Astigmatism: When cornea flattens patchily, the result is astigmatism which disrupts the focus of near and distant vision.
- Presbyopia: It is a natural process and related to the age factor. As we become old, there is certainly some loss of vision making vision blurry.
What are the risks associated with Lasik Surgery?
Most of the surgeries involve risks and Lasik surgery is one of them. Here is a look at some of them:
- You may not get the desired clear vision if the laser removes too little tissue from your eye. In clinical terms it is known as Undercorrection. You may require another enhancement surgery to get positive results.
- Since there is a possibility of Undercorrection, there is also a possibility of overcorrection. The laser subsequently may remove too much tissue from your eye.
- As your eyes heal after the Lasik Treatment, you might feel unusual dryness in them in the first six months or so.
The results of Lasik surgery are more on the brighter side. People having undergone Lasik Treatment have experienced improved vision without further need of glasses or contact lenses.
