Effect of sceral buckling surgery on accommodation amplitude in Rhegmatogenous Retinal Detachment patients

Abstract

Presbyopia Is an unescapable process. There have been efforts to restore near vision and the more desire to overcome presbyopia has led to new surgeries and inventions in recent decades. Scleral buckling is a Procedure performing to save vision in rhegmatogenous retinal detachment and it is Reported to help accommodation and improve near sight. This study is conducted to measure accommodation Accurately by using a clinical abberometer(itrace) in buckled RRD patients and to compare Accommodation Amplitude(AA) in operated eye versus fellow eye and also inspect changes in non-operated eye AA before and after surgery.

methods and Materials :41 eyes from 21 Participants enrolled in this study, operated group (20), conroll group (20) and pseudophakic group (1),participtants could look at far target and and 50,45,33,25,22.5cm targets through instrument and sphere refraction difference used to calculate accomodation, using itrace aberrometry AA was measured in control group preoperatively and 7.6 ±4.5 months post operatively AA in all groups were measured in the same manner

Results: study participants 13 male and 8 female, mean age 32.6±9.1, pseudophakic patient revealed 0.06±0.13 diopter AA,mean AA in operated group was 1.85D and in the fellow eye group was 1.69D, difference was not statically significant(pvalue:0.61) Maximum AA was 4.30D and minimum AA was 0.11 There were no statically significant changes in AA in control group after surgery induce myopia 2.93D post operatively was confirmed.
