A Look Into LASEK

In recent years, millions of patients and surgeons have chosen Laser in situ Keratomileusis (LASIK) over Photorefractive Keratotomy (PRK) because of the quick recovery time, less pain and a decreased risk of haze in the cornea. LASIK is able to deliver these results because the laser reshapes the cornea under a protective flap. However, not all patients are candidates for LASIK. Some patients have corneas that are too thin for their required prescriptions or pupil sizes. These patients would normally require PRK. Dr. Lin has pioneered a technique called, MICRO-LASIK, in which a significantly thinner flap is created, and enables most of these patients to safely achieve natural vision. For patients that have extreme refractive errors, very thin, or abnormally shaped corneas Laser Epithelial Keratomileusis (LASEK) may be the only option. Dr. Lin is one of the first surgeons in the Los Angeles area to offer LASEK.
How it Works
STEP 1 - Mark edges of corneal epithelium (outer layer) and soften the corneal epithelium with solution.

The LASEK Procedure

Laser Epithelial Keratomileusis (LASEK) is an innovative procedure virtually identical to PRK that has improved recovery time and safety profile. PRK was FDA-approved over 20 years ago and involves removing the epithelial layer of the cornea and then utilizing the excimer laser to reshape the cornea. The LASEK procedure is similar to PRK, except that instead of scraping or lasering the epithelial layer away, it is preserved as a replaceable flap.

A cool beam excimer laser is then used to reshape the cornea to correct the refractive error. The epithelial flap is then replaced without sutures and a bandage contact lens is placed over the cornea to secure the flap. Most patients do not experience any discomfort during the 15-minute procedure. After 4 days, most patients achieve driving vision and no longer experience any of the mild discomfort felt during the initial recovery period.
