Lasek Eye-Surgery
What is Lasek?
LASEK stands for Laser Epithelial Keratomileusis. It utilizes a laser to help correct nearsightedness, farsightedness, presbyopia, and astigmatism. While both LASIK and LASEK utilize a laser to reshape the eye, the procedures vary in how they get this done.
Understanding Lasek
The first step in the common LASIK procedure is to cut a small flap into the outer layer of the eyeball and then to reshape the eye. The other procedure, LASEK, does not have to cut as deep into the eye and only removes the outer layers of skin (the epithelial tissue). This means that LASEK can be a great option for patients who otherwise would not be a candidate for other laser-assisted vision procedures.
The first step of a LASEK procedure is to make a small incision on the top outer layer of the cornea. Then a special solution is placed on the eye for approximately thirty seconds. This helps to loosen the upper layer of skin, which is then folded to one side. The laser is then used to reshape the stroma or the middle layer of the cornea. Once the stroma has been properly shaped, the epithelium can be replaced and allowed to heal. The results are a clear vision without the need for corrective lenses!
Benefits of Lasek
There are some patients who cannot have LASIK surgery because they have thin, flat, or irregularly shaped corneas. Because LASEK does not cut deeply into the tissue of the cornea, it can be a great fit for many patients who could not have other corrective surgeries.
Some additional considerations are the effects of LASEK on dry eye syndrome. Some patients have faster recovery of the corneal nerves in the eye.
Because these nerves have a role in the body’s response to lubricating the eyes, there is less frequency of dry eyes in patients who have received the LASEK surgery rather than LASIK. This is a common complaint from patients who are just recovering from a LASIK surgery. Finally, there is some concern for LASIK of cutting irregular flaps during the procedure. The approach that LASEK uses can avoid this entirely offering an additional benefit of this surgery.
