LASIK (laser-assisted in situ keratomileusis) and advanced surface ablation procedures like LASEK and PRK are all laser vision correction techniques used to correct nearsightedness, farsightedness, and astigmatism. They each use a computer-controlled excimer laser to reshape the cornea.
LASIK involves the creation of a thin corneal flap and the use of the laser on the internal tissue of the cornea. The surgery takes only a few minutes per eye and is generally painless. Afterwards, there is very little discomfort, and patients are often able to return to work the next day. Post-operative care typically involves at least three office visits.
Unlike LASIK, PRK and LASEK do not involve the creation of a flap. With PRK and LASEK, the epithelium (skin layer of the eye) is either removed (PRK) or moved gently aside (LASEK), and the laser operates on the surface of the cornea rather than internally. Again, surgery takes only minutes per eye and is generally painless. Post-operative recovery for PRK and LASEK, however, takes a little longer than recovery from LASIK. To assist healing after PRK/LASEK surgery, a clear bandage contact lens is placed over the cornea during the 3-5 days needed for the epithelium to re-grow. Additionally, LASEK/PRK patients typically use steroid drops for 3-6 months, and there is somewhat more discomfort during the healing process.
There are some patients who prefer LASEK/PRK, as well as some medical conditions that make advanced surface ablation more suitable. Dr. Gulani will help you determine which procedure is best for you.
