New Algorithm Allows Doctors to Predict Corneal Power after LASIK

Corneal Power after LASIK - Mobile, AL Your cornea is the clear, protective outer layer of your eye that, along with the sclera (white of the eye), serves as a barrier to dirt, germs, and other things that could damage your eye. The cornea also is part of the mechanism responsible for your vision, bending the light entering your eye. The curvature of your cornea helps determine how well your eye focuses on objects far away and close up.

One way ophthalmologists have measured corneal power and predicted it in LASIK patients is by using historical patient data. But this method is rather useless if the doctor can’t obtain the data. A new algorithm uses a variable keratometric approach, measuring the anterior (forward) curve of the cornea. A study comparing this method with traditional methods showed no statistical difference in the results. The study concluded that this adjusted keratometric method “can be considered (an) appropriate method … for estimating the corneal power in corneas with previous myopic laser refractive surgery when posterior corneal surface data are unknown in clinical practice.”

In other words, when a doctor doesn’t have your previous corneal measurements, this method can be used for predicting corneal power just as well as methods requiring those measurements, giving ophthalmologists one more tool to make sure your LASIK results are as accurate as possible.
