The LASEK method (Laser Epithelial Keratomileusis) is a proven alternative to the LASIK method. First, the eyes are prepared for the treatment with anesthetic eye drops. Afterwards, the outermost cell layer of the cornea (epithelium) is detached and removed. Once the epithelium is removed, the corneal layer to be reshaped is exposed, and the actual laser eye correction can begin.
The corneal tissue is shaped with the excimer laser to achieve the correct curvature. The refractive error is corrected. The eye is now able to properly focus incoming light, allowing a sharp image to form on the retina. After the laser procedure is completed, a therapeutic contact lens is inserted into the eye. It protects the eye after the epithelium has been removed and aids in the healing of the wound surface. The contact lens remains in the eye for approximately 3 to 5 days.
