title: [A three-month follow-up study of excimer laser photorefractive keratectomy for myopia].
abstract: In order to evaluate the efficacy of photorefractive keratectomy (PRK) in the treatment of myopia, we summed up and analysed the 3-month follow-up data on 145 cases treated in our hospital. Prior to PRK, refractive dioptal was -1.5 to -11.5; visual acuity was less than 0.1 in 137 cases (94%) and less than 0.5 in 8 cases(6%). One month after operation, the mean refractive dioptal was +0.98 +/- 0.88; visual acuity increased to > or = 1.0 in 95 cases (66%) and to > or = 0.5 in 142 cases(98%). Three months after operation, the mean refractive dioptal was -0.13 +/- 1.09; visual acuity increased to > or = 1.0 in 104 cases(72%) and to > or = 0.5 in 135 cases(93%). There was no severe complication noted in all cases. The results demonstrate that PRK is and effective, safe and predictable treatment for myopia.
