Journal of Cataract & Refractive Surgery: March 1994 - Volume 20 - Issue - p 229-233 doi: 10.1016/S0886-3350(13)80758-4 Buy Metrics Abstract We evaluated the results of photorefractive keratectomy (PRK) with an excimer laser on 45 consecutive myopic eyes (23 patients) that were followed two years or more. The myopic range was from -2.00 diopters (D) to -6.00 D with astigmatism less than 1.50 D. Uncorrected visual acuity better than 20/25 was achieved in 88.9% of all cases two years postoperatively. Best corrected visual acuity was equal to or better than preoperatively in 95.6% of eyes. The difference between the attempted and achieved correction was within ±1.00 D in 91.1 % two years postoperatively. Keratometric readings and central comeal thickness showed a gradual restoration until six months postoperatively and then stabilized. The cornea was clear in 66.7% of the eyes. The most common subjective complaint was decreased night vision two years after PRK. From our experience, excimer laser PRK is a predictable and effective surgical method to correct myopia up to -6.00 D in a single-step procedure. © Williams & Wilkins 1994. All Rights Reserved.
