Is There Still A Flap About Lasik:
From Waterskiing To Night Vision
_Lasik is the surgery miracle that has allowed many millions of people around the world to correct their vision problems and to see better than before. Still it is necessary to be cautious around certain activities, one in particular being water sports according to some reports.
There are reports of there being a danger of a person dislodging their cornea flap if they are not careful.
The one sport pointed out as being the most dangerous was water skiing. You know, at those fancy lakes where for fun and sport you strap on skis and get pulled around by a motor boat.
Well, the recommendation by doctors is to have the water skier wear a pair of eye goggles all the time when doing this activity.
The flap in the cornea is something that all Lasik patients have to deal with as a potential for concern, whether it was made with a microkeratome blade, or it was done by all-laser bladeless Lasik. It heals but it has been treated and still could be vulnerable under some circumstances.
Another problems that is known to persist at least for some period of time, are problems with night vision after Lasik surgery. These night vision problems could affect a person’s ability to distinguish objects at night.
Though these problems are typically transient and wear off for most patients in a few days, in some patients, the symptoms might persist long after the eye heals.
The source of the problem is that under low light conditions the pupil naturally dilates to be able to receive more light. The larger pupil can then absorb light from around the region of the cornea that had been shaped by the Lasik, also known as the flap, which doesn’t happen during the daytime, since the pupil is smaller, it is not dilated.
This is what causes the rather common phenomenon of glare, starbursts and halos around objects seen at night. It can be a really serious problem for some while driving at night. Fortunately, this problem tends to dissipate over several months to a years time usually at most.
Night vision problems are known to be caused by the differences between the untouched portion of the cornea, and the part of the cornea that has been altered by Lasik surgery.
This can be even more severe if for whatever reasons a patient is required to undergo a second Lasik procedure. This causes the cornea to become even flatter after each procedure.
These problems are reportedly dropping on the one hand as doctors gain more experience with Lasik and pre-operation screening of patients. If a patient with large pupils under dilation is deemed suitable for treatment, then their treatment can be altered accordingly.
Custom Lasik has been found, with its included use of wave-front maps of the eye, to be able to more successfully treat a larger area of the eye, which then can be mapped onto a larger pupil, with better post operative results for night vision.
