ABSTRACT
Reoperation of Photorefractive keratectomy(PRK) may be considered for regression, corneal haze, topographic irregularity, and a combination of these complications. We have studied the results of reoperation after myopic PRK in 113 eyes. Between 1992 and 1994, we observed 3,053 eyes of 1,583 patients who underwent PRK over year follow-up. We analysed 113 eyes which showed regression with or without opacity and underwent reoperation over one year follow-up. For reoperation, we used the VixX Twenty/Twenty excimer laser. Of the 72 eyes on regression, 53 eyes(73.6%) showed successful result(spherical equivalent within +/-1.0D), but 19 eyes(24.6%) showed repeated regression after the reoperation. Of the 33 eyes with corneal opacity and regression, 14 eyes(42%) showed good results. Of the 8 eyes with a central island, the results was good in all of the cases. No complications were observed. In conclusion, the reoperation rate was 3.7%(113/3053). The main cause of reoperation was regression, and the best result of reoperation was central island. 75 eyes out of 113 eyes(66%) showed good results(spherical equivalent within +/-1D). Reoperation may be considered for regression with or without corneal haze and central island in PRK.
