Myopia (Nearsightedness)

Surgery

Several types of surgery for nearsightedness (myopia) are available to change the shape of the cornea and refocus light directly on the retina. However, surgery cannot correct pathological myopia.

The goal of surgery is to allow people who are nearsighted to see clearly without corrective lenses or to be less dependent on corrective lenses. Most doctors consider 20/40 vision or better after surgery a satisfactory result. People with 20/40 vision or better are allowed to drive a car without corrective lenses. Overall, most people who have surgery achieve 20/40 vision or better after surgery.

Laser surgeries include:

• LASIK (laser in-situ keratomileusis), which is currently the most commonly used corrective surgery for nearsightedness in the United States. LASIK has a high success rate and low complication rate for low to moderate nearsightedness. It may also be used to correct more severe nearsightedness. In general, it requires less healing time, is less painful, and offers a faster visual recovery than photorefractive keratectomy (PRK).
• PRK (photorefractive keratectomy) and lasek (laser epithelial keratomileusis), which are similar surgeries. They are another type of corrective surgery for nearsightedness that is used frequently. Like lasik, PRK and LASEK have high success rates and low complication rates for low to moderate nearsightedness. They may be used instead of radial keratotomy (RK) to correct severe myopia………….

Surgery Choices

Laser surgery for nearsightedness changes the shape of the cornea to refocus light directly on the retina. There are three main types of laser surgery used to treat nearsightedness.
LASIK (laser in-situ keratomileusis) makes a small flap in the cornea and removes some of the tissue exposed by the flap.

PRK (photorefractive keratectomy) and LASEK (laser epithelial keratomileusis) use a laser to reshape the cornea. The laser is applied to the cornea after the surface layer has been removed.

Radial keratotomy (RK) uses several incisions on the cornea to change the curve of the cornea over the pupil……………….
