# What is LASIK eye surgery?

LASIK is a laser eye surgery that reshapes the cornea to correct short-sightedness, long-sightedness, and astigmatism. It is one of the most commonly performed vision correction procedures worldwide.

## How LASIK works

A thin flap is created on the surface of the cornea, then a precise excimer laser is used to reshape the underlying tissue. The flap is then repositioned, allowing for rapid healing and a quick visual recovery.

- Usually suitable for people with stable prescriptions
- Both eyes are commonly treated on the same day
- Most people return to normal activities within a few days
