LASEK eye surgery is an alternative laser vision correction procedure for people who are not good candidates for LASIK. It is something of a compromise procedure between LASIK and PRK and designed to avoid the limitations created by the LASIK flap, but preserve the outermost layer of the cornea, unlike PRK, which ablates it away. LASEK eye surgery utilizes a flap that is created only in the outermost layer of the cornea and because the flap is shallower, it can be an option for people with thin or steep corneas who may not be candidates for LASIK.
Typical recovery requires more time compared to LASIK. The vision results of LASEK vs LASIK are very similar.
