Is there some drug treatement (pills, eye drops) to treat corneal scars I developed from having LASEK 12 years ago?

depends if the scar is clinically significant ie decreasing your vision, often we can see it on slit-lamp but it's mild so no need to treat. if it is decreasing vision you can have a PTK as that other MD said, but i would suggest a long course of topical steroids, that usually works, of course you need to be checked regularly to monitor IOP/make sure you aren't developing glaucoma

PTK, a laser treatment to remove superficial corneal scars like yours, have been used for 3 decades for this.Mitomycin C is a safe medicine that is used at the time of the surgery. It is applied the by the surgeon once at the time of surgery and helps avoid scarring afterwards.If you smoke. Stop now. Use preservative free lubricant drops starting now. Take vitamin C and wear polarized sunglasses when outside. Start all of that before the treatment and continue it and follow the direction on steroid drops which are used for a few months afterwards. Stopping the drops too soon will negate the effect of the treatment.
