Abstract

Many studies have shown the effectiveness of PHOTOREFRACTIVE KERATECTOMY (PRK) in correction of vision in low and moderate myopia. To evaluate the results of 193 – nm exeimer laser PHOTOREFRACTIVE KERATECTOMY for highly myopic eyes, we reviewed refractive outcome of 43 eyes of 30 patients. Most eyes were treated with 1 – step operation, using a 6 mm optical zone. Forty three eyes were treated for myopia, which were between – 6.40 and – 16.90 diopters. The mean preoperative refraction was – 9.50 D. All eyes were followed for at least 12 months.At 12 th month visit, 30.2 % and 60.5 % of eyes achieved correction within 1 and 2 D of attempted correction, respectively. At this time, 62.7% of eyes obtained 20/40 visual acuity or better uncorrected. At 1 year, 13 % and 8 % of eyes lost 3 and 4 lines of best – corrected visual acuity, respectively. Also 13 % of eyes lost 2 lines. 12 months after PRK, 5 eyes developed corneal haze grade 2 and 2 eyes, grade 3 (0 – 5 scale). There was much under correction seen in this group compared with patients undergoing PRK for low and moderate myopia.PHOTOREFRACTIVE KERATECTOMY for HIGH MYOPIA, though effective, is not a safe and accurate procedure and is less predictable and stable than performing it for low and moderate myopia.
