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:
“Unlike any other visual image, a photograph is not a rendering, an imitation or an interpretation of its subject, but actually a trace of it. No painting or drawing, however naturalist, belongs to its subject in the way that a photograph does.”
—John Berger (b. 1926)
