Loss of Corrected Visual Acuity - Beware
Lots of info on the web, but one contribution from me ...
A friend had the lasik surgery done, and though his eyesight improved in terms of needing less strong glasses, he did experience some glare from lights at night, and also **lost** about 1 lines worth of visual acuity between his before and after corrected vision.
I've heard this is fairly typical.
