[Excimer laser photorefractive keratectomy in myopia].

The authors present an account on excimer laser photorefractive keratectomy on 254 myopic eyes with a minimal follow-up period of 6 months. The mean preoperative refraction -6.31 +/- 4.02 D was reduced to -0.92 +/- 1.3 D. A difference between the planned and achieved correction of less than 0.5 was recorded in 33.5% eyes, less than 1.0 D in 59.4% eyes and less than 1.5 D 77.6% eyes. As to complications the following were recorded: astigmatism more than 0.5 D (7.9%), problems with epithelialization (5.5%), steroid induced increased intraocular pressure (3.9%), corneal turbidity higher than 2 (1.2%). Based on the results the authors revealed that excimer laser photorefractive keratectomy is safe and effective refraction surgery for low and medium myopia with the possibility to predict the resulting postoperative refraction.
