Myopia Treatment

[kiyakiashita]

Nearsightedness may be corrected with eyeglasses, contact lenses or eye surgery. Depending on your vision problem, you may need to wear your glasses or contact lenses all the time or only when you need distance vision, like driving, seeing a chalkboard or watching a movie. If you're nearsighted, your prescription is a negative number. The higher the numeral, the stronger your lenses will be.

Refractive surgery can reduce or even eliminate your need for glasses or contacts. The most common procedures are performed with an excimer laser.

1. In PRK the laser removes a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina.
2. In LASIK — the most common refractive procedure — a flap is cut through the top of the cornea, a laser removes some corneal tissue, and then the flap is dropped back into place.
