Lasek / PRK
An excellent alternative to SMILE or LASIK.
PRK/LASEK procedures remove a thin cell layer from the top of the eye so the laser can reshape the underlying cornea. This surgery may be an option for those who are not eligible for LASIK, SMILE or refractive laser surgery.
Effective. A Great alternative.
What is Lasek/PRK?
PRK, Photorefractive keratectomy, was the first laser eye surgery method, beginning in the late 1980s. Thousands of patients were treated with PRK before the invention of LASIK. PRK/LASEK procedures continue to be an option for people with mild nearsightedness (myopia), farsightedness (hyperopia), as well as astigmatism .
Some people choose PRK/LASEK over LASIK, despite the longer recovery period and discomfort after surgery, to avoid the flap.
PRK is often thought to be synonymous with LASEK, but they slightly differ in the first step. Both surgeries remove the outer top layer of cells (epithelium) on the eye with an alcohol solution to expose the sub-layer of the cornea to the laser. In PRK, this layer is completely removed. In LASEK, it is pushed to the side and put back on the eye after surgery.
When the eye is exposed, a laser reshapes the front of the eye so that light passing through is focused properly onto the back of the eye. Finally, a protective bandage lens is placed over the eye until the epithelium grows back, usually within a few days. Full vision recovery takes approximately one month or longer and is longer than alternative Laser Vision Correction methods.
Increased eligibility: This procedure can also be suitable for thinner corneas. PRK/LASEK only removes the very top outer layer of the eye leaving the maximum amount possible of remaining tissue for the laser to shape.
No flap complications: Possibilities of flap-related complications during and after surgery are eliminated with PRK/LASEK: There is no risk of flap displacement.
Epithelium removal: An alcohol solution will loosen the thin, outer layer of the eye.
Surface reshaping: A pre-programmed laser removes corneal tissue to correct the refractive error.
Long visual recovery: After surgery, the doctor will apply a bandage contact lens to assist the healing process, which is typically removed within a week. Vision may take a month or more to stabilize.
