LASIK Flap Surgery. Since gaining approval for use in the United States in 1995, LASIK surgery remains one of the most popular procedures to correct short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism. During the LASIK procedure, the surgeon carefully creates a thin flap that is gently folded back to expose the corneal surface for a second laser to reshape the cornea.
The flap is then carefully re-folded over the treatment area, acting as a bandage as the eye heals. Most patients see their vision improve within hours after treatment. Many are ready to return to work or their normal activities the following day. The main attraction towards LASIK is its relative comfort, fast visual recovery and short down time away from work.
One concern after LASIK is the potential for the flap to be dislodge following a traumatic injury to the eye. As a result, some patients who may be at higher risk of trauma such as contact sports athletes and members of the security services may choose to avoid LASIK.
