8 months post op of LASIK, my vision went from -6.5, -4.0 to -1.5, -1.0. Is this normal?

Question

I'm currently 32 years old and had LASIK 8 months ago. My vision before the surgery was (-6.5, -4.0). After, it went to (-1.5, -1.0), not what the doctor had anticipated. What concerns me is: is it usual to see that amount of under correction? Could it be that is just my eyes that didn't respond well to the surgery?

Brian Davis, MD · Answer

Under correction is probably the second most common adverse effect of Lasik surgery. Dry eye is the most common adverse  effect. Under correction is not necessarily normal but it is relatively common. It is more common if the prescription is unstable prior to the surgery which tends to occur with patients under 30 years old. Prior contact lens use also can make the prescription inaccurate prior to the surgery and cause under correction.it sounds like you may need an enhancement assuming your prescription is now stable and your surgeon feels it is safe. Most patients can do very well with an enhancement.
