LASEK laser eye surgery
Introduction
LASEK laser eye surgery is a newer surgery that combines many of the benefits of older vision correction surgeries, explain doctors at The Cleveland Clinic.
Laser epithelial keratomileusis, or LASEK, combines benefits of the two most commonly performed procedures -- LASIK and PRK. LASEK laser eye surgery is used to treat astigmatism, nearsightedness or farsightedness.
In LASEK laser eye surgery, the epithelium, or outer layer of the cornea, is cut not with the microkeratome cutting tool used in LASIK, but with a finer blade called a trephine and a 20% alcohol solution.
What Are the Advantages of LASEK Laser Eye Surgery?
- Complications associated with cutting and reattaching
the flap in the cornea are avoided.
- LASEK laser eye surgery causes dry eye less frequently than LASIK laser eye surgery.
What Are the Disadvantages of LASEK Laser Eye Surgery?
- Longer visual recovery time compared to LASIK laser
eye surgery. Many LASEK patients will not fully recover functional vision for
1 to 2 weeks while their eye heals, which is similar to the healing time
experienced in PRK laser eye surgery. LASIK laser eye surgery patients often
have good vision by the day after surgery.
- LASEK laser eye surgery may cause more pain and
discomfort than LASIK , but less pain than PRK laser eye surgery. Most LASEK
laser eye surgery patients say the discomfort lasts about 2 days or less.
- Patients need to wear a "bandage contact lens" for
about 3 or 4 days after LASEK laser eye surgery to serve as a protective layer
between your blinking eyelids and the treated eye surface, which is not
necessary after LASIK.
- Patients must use topical steroid drops for several weeks longer than that used after LASIK laser eye surgery.
- Questions To Ask Before Surgery - Surgery questions to ask prior to having a procedure are important. Your surgeon should be available to answer your surgery questions prior to the procedure.
- Astigmatism - Astigmatism is a common form of visual impairment in which part of an image is blurred, due to an irregularity in the curvature of the front surface of the eye, the cornea.
