Lasik for Hyperopia

Laser in-Situ Keratomileusis (LASIK) can be used to treat low to moderate levels of farsightedness (hyperopia) with the goal of reducing or eliminating dependence on corrective lenses. Farsightedness occurs when the cornea is too flat or the eye is too short. This causes the focal point of light to fall behind the retina, rather than on the retina, resulting in blurry near vision. LASIK uses the computer-controlled precision of the Excimer laser to treat the inner tissue of the cornea.

The procedure is done using eye drop anesthesia, and while you may feel pressure, the technique is not painful. First, an instrument known as a microkeratome makes a protective flap in the outer layer of the cornea. The Excimer laser sculpts the internal corneal tissue to the correct refractive power by steepening the curvature of the exposed corneal tissue. The "steeper" cornea allows light rays to focus more directly on the retina, thereby reducing farsightedness. After a few minutes of drying, the corneal flap is laid back in its original position. Due to the cornea's extraordinary natural bonding qualities, stitches are usually not required.

Although the vast majority of patients see 20/40 or better postoperatively, individual results cannot be guaranteed. The surgery is performed on an out-patient basis and most people return to work within one to three days. As with any surgical procedure, side effects and complications may occur.
