What Happens During Lasik Correction

Lasik or laser-assisted in situ keratomileusis has been around long enough for the doctors and patients to trust the procedure. The apparatuses used in Lasik correction have evolved by so much that the procedure is now embraced by almost all eye doctors. But what really is involved when you undergo a Lasik procedure?

There are three basic steps that are involved in Lasik:

1. Creation of a flap in your cornea,
2. Destruction of the stroma to reshape the cornea, and
3. Repositioning of the flap back to the eyeball.

The first step involves cutting a portion of your cornea in perfect circular motion leaving a hinge to hold the flap in place. This is done in either of two ways: using a mechanical instrument called a microkeratome, or using a laser assisted cutting procedure, thus the birth of IntraLase. The latter is preferred more than the other for several reasons. Once the flap is made, the destruction of the stroma can begin.

To correct vision problems (astigmatism, hyperopia, and myopia), Lasik reshapes the cornea by destroying a very thin layer of the inner cornea or the stroma. An Excimer laser is used for this purpose. Highly controlled and refined laser beams are fired to the stroma, which touches the cells in quadrillionth of a second, to destroy them. The destruction leaves a dent that permanently reshapes the cornea, and thus correcting the problem.

The last step in Lasik vision correction is the repositioning of the flap. The flap is carefully lifted and covered over or put back to its original position. Although this step is relatively straightforward, this can be the source of some post-procedural problems when done carelessly. For instance, doctors are very careful not to leave debris or pockets of bubbles inside the cornea before placing the flap back.

If you are asking if something serious could go wrong during any of these steps, then the answer is a resounding yes. However, with the development of the apparatuses used, training and research invested on Lasik correction, etc., the possibilities of a mishap are greatly reduced. Lasik is still considered a safe vision correction procedure. Just choose your eye doctor carefully though.
