I had PRK about 3 months ago and my vision is currently 20/40. Any suggestions?

50 year olds are certainly candidates for Lasik or PRK, if other things are appropriate. High corrections can be treated up to a certain level. Either the eyes will be adjusted for distance and you will wear reading glasses for close or you can have blended monovision.

Typically, you can not tell just by looking with a microscope that a person has had PRK. In most cases, you can't tell just by looking with a microscope that a person has had Lasik either. Testing with topography will reveal the microscopic curvature changes caused by PRK or Lasik.

Being patient after PRK is by far the hardest part. Unfortunately, PRK healing can be exasperatingly slow in some cases. Most people are seeing a "weak 20/20" after 6 weeks, but many others are behind that schedule. Your progress up to this point does not reflect on how you will eventually see....

Unfortunately, there is no way to increase the thickness of your cornea. Corneal thickness is important for laser vision correction because in order to correct your vision, we need to sculpt/reshape the cornea with the laser - doing this results in the removal of corneal tissue. Larger glasses...

You had a high prescription.   Even though the enhancement rate (retreatment) is less than 2 percent for most surgeons and surgeries in your group it may be double or triple that rate.   As long as glasses corrects you to 20/20 it is likely that with an enhancement yiu will do well if...

Haze after PRK is managed with UV protection (sunglasses) and topical steroid drops. Often surgeons use a topical medicine called Mitomycin C immediately after the procedure to minimize haze formation. Most surgeons employ a post-operative steroid drop taper over weeks to months. Typically I use...
