Key Facts About Lasik

What is Lasik?

Lasik stands for “laser-assisted in situ keratomileusis”. It is an irreversible refractive surgical procedure done by laser. Its goal is to restore vision by reshaping the cornea - the crystalline lens through which we see.

Who is Lasik for?

Lasik eye surgery can help you if you are myopic (nearsighted), hyperopic, or if you are astigmatic (images both far and near are distorted due to asymmetrical cornea). You must be over 18 as before that the cornea is still developing.

It is not suitable if you have presbyopia - sometimes known as aging eyes.This is a condition that arises at the age of 40 and up due to a stiffening of the lens and a weakening of the eye muscles. As presbyopia is not caused by the shape of the cornea, Lasik cannot help this condition except via a procedure known as monovision in which one eye is optimized for far vision and the other for near vision.

There are also various contraindications which your doctor will test for and tell you about.

Why should I undergo Lasik?

Lasik is a quick, painless, safe procedure that can free you from the need for glasses and contact lenses. Results are immediate You will be able to see very clearly without glasses directly after the operation, or at least the next day.

How is Lasik performed?

When you are under local anaesthetic, the surgeon creates a very thin circular flap in the cornea with a special knife or a laser. He then folds the flap back and removes some corneal tissue with an excimer laser. Finally he replaces the flap.

For nearsighted people the target is to flatten a too-steep cornea, while for the farsighted, the objective is to steepen the cornea. To correct astigmatism, the surgeon smoothens the irregular cornea into a normal shape.

Where is Lasik performed?

When looking to have Lasik performed, you should consider a well-known, and trusted center. This will require thorough search and study as there are hundreds of centers in each state and city, all with different prices.
