RK & AK (Radial Keratotomy - Astigmatic Keratotomy)

The cornea and lens combine to focus visual images on the back of the eye. When the overall shape of the eye is incorrect or the curvature of the cornea is abnormal, visual images are out of focus. The cornea accounts for approximately 2/3 of the focusing power of the eye. By surgically changing corneal curvature, most or all of the blur can be overcome.

Astigmatic Keratotomy (AK) is used to help people with astigmatism. Astigmatism is an uneven curvature of the cornea, but which is symmetrical and not irregular. It also has an axis. (00 at the right horizontal progressing counter-clock-wise to 900 at the top to 1800 at the left horizontal while looking at the eye). It is curved more in one direction than the other, causing a distortion in vision. During AK, one or more surgical incisions are made in the cornea. These incisions help eliminate the uneven curvature and "round out" the cornea. A rounder cornea means objects no longer appear blurred or distorted. AK is sometimes performed at the time of cataract surgery, in order to reduce or eliminate the patient's preexisting astigmatism.

RK

Radial Keratotomy (RK) is a surgical procedure that can help people with mild to moderate myopia. The technique has been in existence for more than thirty years. During RK, tiny spoke-like incisions are made in a "radial" pattern around the cornea. These cuts in the cornea serve to change the curvature of the cornea. To correct for nearsightedness, the cuts are used to flatten the cornea.

As with laser vision correction, the vast majority of patients have had their vision corrected to 20/40 or better. It is most effective when treating low to moderate levels of nearsightedness.
