title: [Experience with excimer laser photorefractive keratectomy].
abstract: The correction of refractive errors based on superficial ablation of the cornea has a couple of years long history. Authors performed photorefractive laser surgery with the Aesculap Meditec MEL 60 ArF excimer laser in 221 eyes of 147 patients. The follow-up time varied between 2-24 months, average 8 months. They have treated the following groups: 1. group: 0-6.0 D; 2. group: -6.5-9.0 D; 3. group: eyes with refractive error above -9.5 D; 4. group: hypermetropic eyes; 5. group: eyes with astigmatism.
  
  
  RESULTS
  In the 1. group the average -4.58 +/- 1.25 D refractive error decreased to -0.19 +/- 0.53 D in the follow-up time; 2. group: from -7.46 +/- 1.22 D to -0.45 +/- 0.83 D; 3. group: -13.76 +/- 5.46 D to -1.52 +/- 1.74; 4. group: +428 +/- 1.6 D to +0.91 +/- 2.41 D; 5. group; from -6.74 +/- 2.81 D sph -2.3 +/- 1.54 cyl to -0.51 +/- 1.3 D sph -0.54 +/- 1.06 D cyl. According to their experiences they conclude: the best results have been achieved in the first two groups and in eyes with astigmatism (1., 2., 5. groups). In severe myopia cases postoperative correction is usually needed, which is significantly smaller than the preoperative spherical correction. The method is able to change the refractive power of the cornea and provides an efficient alternative to the spectacles and contact lenses.
