Paper Abstract

We have performed excimer laser photorefractive keratectomy operations with a Schwind Keratom 2F to correct near- sightedness. 613 eyes of 348 patients were treated by this ablation method. We have selected 318 case, where the follow-up was at least 6 months long. The intended corrections were in the range of -1.75 D to -9.0 D for myopia. The optical zones were 5.5 and 6.0 mm. We present various results of the treatments: change of visual acuity, residual spherical refractive error, time valuation of healing, and ablation speed. We have found that the ablation speed of human cornea is depends on the age of patients. An equation is also presented to describe the relation between age and ablation speed.
