Abstract

Background and Aims: The previous studies have shown and with the knowledge of the complications of surgeries and improvements in the field of surgeries, customized photorefractive keratectomy(PRK) as a new method of surgery.This study is a comparative assessment of changes in High Order Aberration in Hyperopic and Hyperopic Astigmatism Patients pre- and post- customized ablation photorefractive keratectomy..

Materials and Methods: This cross-sectional study,20 eyes of 12 patients (8 female and 4 male) were underwent customized PRK technique by technolas 217p. The patients were divided into three groups based on the amount of subjective hypropia,hyperopia between +0.50 and +1.75D have been as the mild hyperopia group,hyperopia between +2.00 and +3.00D as moderate and high hyperopia group were included hyperopia between +3.25 and +5.00D. Subjective refraction ,best corrected visual acuity(BCVA) and high order aberration with 6 millimeter pupil was measured pre- and postoperatively.

Results: High order aberrations(HOA) was increased in each hyperopic groups especially in high hyperopia group.

Conclusion: Customized PRK surgery can be used as an effective, secure and predictable method of surgery for correction of hyperopia up to 3D but for patients with higher than 3 diopter of hypriopia it doesn’t seem like an effective method.
