I had LASIK in 1997. I am 20:20 but with severe night vision problems. A surgeon suggests having the flap lifted to smooth the cornea and remove scar tissue, then reattach the flap with sutures. She does not know whether this will help the night vision problems. I asked about widening the ablation zone. She says it can't be done to a 20:20 eye.

Anyone have experience with this flap procedure?

"Severe night vision problems" implies an optic zone that is smaller than the dark adapted pupil. 20/20 implies that the optics overlying the ablation zone are fairly regular (i.e., without significant aberrations).

Lifting and suturing the flap would alter the central flap dynamics, essentially where you are NOT having the problem. If your surgeon does not know whether this will help the night vision problem, then it seems rather pointless and potentially risky to your otherwise good acuity.

If your night vision problems are abated with Alphagan (brimonidine) or a weak concentration of pilocarpine, then pupil size is more likely the issue.
