Abstract: 

Introduction: 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.
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 hyperopia, 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 group especially in high hyperopia group.
Conclusion: Utilization of such non-invasive non-pharmaceutical tools as blindfolds and earplugs are recommended in cardiac intensive care units since they are cost effective and non-complicating and that they result in an improvement in sleep quality of the patients who are suffering from cardiac complications.
