Myopia surgery is an option for treatment for people who are nearsighted and rely on glasses or contact lenses to see objects far away. One of the causes of myopia, occurs when the eye is longer than normal, causing the eye to focus in front of the retina instead of on it, creating a blur.
Refractive eye surgery is one of the most popular and widely used treatments for myopia. There are four types of refractive surgery: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), laser epithelial keratomileusis (LASEK) and epithelial laser in situ keratomileusis (epi-LASIK).
Such myopia treatment uses a laser to reshape the curvature of the cornea, and the results allow people to stop using glasses or contact lenses to correct their myopia.
PRK using a solution of alcohol, or laser energy to remove the epithelial cells of the cornea in order to access the surface of the cornea, known as the stroma, to reshape the eye. Doctors recommend PRK for people with dry eyes or thin corneas would be prone to problems and complications associated with LASIK surgery, which is very similar.
A LASIK procedure requires the surgeon to cut a flap of several layers of the cornea to be able to reshape the tissue underneath. Recovery time after PRK surgery is longer than LASIK because the eye has to regenerate the epithelial layer is removed during the procedure.
LASEK is similar to LASIK and PRK. For a LASEK procedure, the outer layer of cells weakens and then a thin layer is removed to reshape the cornea using a laser. The layer is placed in its original position. Epi-LASEK also requires a piece of the epithelial layer is created, but it is a blunt instrument, plastic, and a flap is created.
The other two types of surgery for myopia make use of implants to permanently repair nearsightedness. Intraocular lens implants are contact lenses that are placed either between the iris and the lens, or between the cornea and iris. The intraocular lens implants can not be felt or seen, and these implants can be removed if the eye of the person continues to change.
