Hi, I recommend to not do lasik unless contacts and glasses don't work. Contacts and glasses give perfect vision without surgery and doesn't leave scars. If you change prescription you jyst buy a new lenses and have perfect vision again. The flap never heals, unfortunately lasik doctors don't inform patients about that.

"Although LASIK remains the most popular refractive surgical procedure, it is becoming apparent that corneal surfaces, cut to create the midstromal flap during surgery, fail to fully reunite postoperatively; surgeons can simply peel back an anterior corneal flap several years later. Such patients... are at risk for progressive visual disability due to general corneal weakness that may progress to ectasia or even traumatic displacement of the insecure flap."

"Your corneal flap will never adhere to the surface of the eye with quite the same strength it did prior to the surgery, so there is a rare but possible risk of the flap becoming displaced with sufficient force." Source (pg 4) Dr. Gary Conrad, Kansas State University Biology Professor: "It was once believed that the flap would re-adhere permanently. However, the unique connective tissue of the cornea and a lack of blood vessels limit its ability to fully heal even years after the procedure." Source "The corneal flap of approximately 160 μm, of one third thickness of the average cornea, has been shown to never heal fully by Seiler and Marshall (personal communication, June 26, 2000). Approximately 22 million corneal fibers are intersected, their severed ends never rejoining, meaning that the flap is held in place only by glycosaminoglycans and peripheral scar tissue. To put it more simply, the corneal flap after LASIK provides no more corneal strength than the wearing of a contact lens." Jory W. Corneal ectasia after LASIK. J Refract Surg. 2004 May-Jun;20(3):286. "Furthermore, if [LASIK] interface transparency is indicative of absent wound healing, one might expect that the interface remains a potential space and flap adhesion is impaired for the lifetime of the flap."
