You might have heard about LASIK alternatives and if you have been told LASIK eye surgery is not a good option we might suggest you consider speaking to a qualified eye doctor about LASEK. LASEK eye surgery (laser epithelial keratomileusis) is a variation on the techniques for PRK and LASIK. Also called epithelial LASIK, E-LASIK or just plain LASEK is ideally used for people with corneas that are too thin or too flat for traditional LASIK. LASEK decreases the chance of complications that can occur when creating the corneal flap during traditional microkeratome LASIK when the cornea is not the ideal thickness.
What Happens During LASEK Eye Surgery?
In LASEK, the epithelium, or outer layer of the cornea is removed using finer blade called a trephine instead of the microkeratome used in LASIK. The surgeon then covers the eye with an alcohol solution (perhaps one part alcohol and four parts sterile water) for around 30 seconds. The solution loosens the edges of the epithelium. After removing the alcohol solution from the eye, the surgeon then lifts the edge of the epithelial flap and folds it back similar to LASIK. Then the surgeon uses an excimer laser to reshape the corneal tissue underneath and then the epithelial flap is placed back on the eye.
After LASEK Eye Surgery
After LASEK a bandage contact lens is put into the eye to allow the flap edges to heal. As in PRK, the bandage contact lens is worn for about three days. You may feel eye irritation during the first day or two afterward. The patient will need to use eye drops (topical steroid drops) for a few weeks after the LASEK treatment to control healing rate.
LASEK vs LASIK
Typical LASEK recovery requires more time to fully return vision, when compared to LASIK. The LASEK recovery period is usually about four to seven days, which is shorter than typical PRK recovery. The vision results of LASEK vs LASIK are very similar results, though LASEK takes more time than traditional LASIK to achieve full visual clarity.
