Abstract

From March in 1991, central photorefractive keratectomy(CPRK) have performed to correct the 700 myopic eyes. With the example of 310 eyes posibly observed over 6 months after CPRK, studed whether it was corrected by retrospective examining. Especilly in the study of 150 patients collected by answering sheet then studied how discomfort they took through complication, and analyzed the cause of change and Indivisual degree of sansfaction with their myopic degree and postoperative permd. This study led to a conclusion that the milder myopia and the longer postoperative period, the more patients sansfaction increased. This is because the change of refractive power become stable and corneal haze decresase with time, Futhermore we dunk that corneal haze and regression occur more frequently in higher myopla, The CPRK is promising surgical treatment for patients with higher myopia but considerable further investigation and longer-term studies are needed to increase satisfaction.
