Visual Rehabilitation After RK
The PERK study demonstrated that people who undergo RK continue to drift toward hyperopia ("farsightedness"). Additionally, many of these people have reached the age where presbyopia occurs. Some also develop cataracts. Their vision can still be restored with epilasik, photorefractive keratectomy, LASIK or phakic lens extraction, or cataract surgery. The corneal curvature has to re measured and modified by history, central keratometry, or contact lens method. Recently, Dr. Fuentes-Páez et al.reported short term clinical and statistically significant improvement in RK patients treated with CROSSLINKING.

Famous quotes containing the word visual:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
