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 .50 and .75D have been as the mild hyperopia group, hyperopia between .00 and .00D as moderate and high hyperopia group were included hyperopia between .25 and .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 noncomplicating and that they result in an improvement in sleep quality of the patients who are suffering from cardiac complications.
