Comparison of Hyperopic Photorefractive Keratectomy and LASIK in the Treat-ment of Hyperopia by Excimer Laser

Overview

The aim of this work is to compare results of the correction of hyperopia by methodof hyperopic photorefractive keratectomy (HPRK) with method of laser assistedkeratomileusis known as LASIK.We evaluate group of 129 eyes operated by excimer laser Keracor 117 manufactu-red by Technolas company. 77 eyes underwent HPRK and 52 eyes hyperopic LASIK(HLASIK). The patients were divided to two groups, the first of which comprised47 eyes with low hyperopia to +3,5 Dsph and the second 82 eyes with highhyperopia. Follow-up period was 12 months results were statistically evaluatedby Student t-test.One year after treatment, in the first group was 62 % eyes with hyperopia to +1,0Dsph after HPRK and 70 % after HLASIK. In the second group it was 32 % and44 %, respectively. No statistically significant differences have been found be-tween the two groups. In spite of that, we consider HLASIK method better thanHPRK from the point of view of stability of results, occurence of complicationsand estimated resulting refraction, expecially in the eyes with low hyperopia.
