title: An analysis on follow-up results of photoreactive keratectomy for treatment of myopia.
abstract: A prospective study of excimer laser photorefractive keratectomy (PRK) was performed with the aim of correcting a range of myopic errors between -1.00 and -10.00 diopters on 422 myopic eyes that were followed for more than one year. At postoperative one year, 91.4% of the eyes had uncorrected visual acuity of 20/20 or better, and 97.4% were within +/- 1.00 diopter of the desired emmetropia, and the corneal haze disappeared in most of the eyes. Elevated intraocular pressures were observed in 20.4% of the eyes. The decrease of one line of the best corrected visual acuity occurred in 7.6% and of two lines in 0.5% of the eyes. We think that the excimer laser PRK is a very predictable, safe, stable, and effective method to correct myopia up to -10.00 D, and longer follow-up will be necessary.
