I had a post lasik enhancement after the doctor made a mistake in adding one next to the axis; however, free enhancement is done four weeks after the original. it has now been three weeks but there is still no improvement. what should i do?

2nd opinion: Sounds like you need a second opinion from another refractive surgeon if your vision does not continue to improve.

Time: I would give it time to stabilize. I think the enhancement should have postponed for 3-4 months after the initial "error." once stable, if there is residual prescription, you may need another touchup.

Not enough info: Would get refracted by your doctor and ask him/her where things stand.

Don't panic: Do not worry. A correction can almost always be found for and rx error after lask. You will be ok. I have done 150, 000 refractive cases since 1979. The usual problem comes when you see another less qualified doctor, who make you worse and blames everything on the other doctor. The tight medical market is causing doctors to be cannibals. They try to put the other doctor out of business, .

Lasik enhancement: It is unclear the extent of the error, but usually enhancements are possible. You should continue to follow up with your doctor and see if there are any other problems -- dry eye, issues with the flap, or perhaps you ended up slightly over or under corrected and you can discuss that with your surgeon, it may be mild, or ask for copies of the report and notes and seek a second opinion.
