A COMPARATIVE STUDY OF POST OPERATIVE ASTIGMATISM IN SUPERIOR VERSUS TEMPORAL APPROACH OF MANUAL SMALL INCISION CATARACT SURGERY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2014, Vol 3, Issue 26
Abstract
[b]BACKGROUND: [/b]Manual small incision cataract surgery is a simple and less expensive technique of cataract surgery but gives visual result almost equivalent to Phacoemulsification. PURPOSE: To compare surgery induced astigmatism in manual small incision cataract surgery through superior and temporal approaches. [b]METHODOLOGY[/b]: One hundred and thirty eyes were included in this study. Eyes with steeper vertical keratometric reading were subjected to superior small incision cataract surgery (SICS) and those with a steeper horizontal keratometric reading were subjected to temporal small incision cataract surgery (SICS). Eyes with no astigmatism were randomly subjected to either type of surgery. Each group had 65 eyes. All the patients were followed up on 1st, 7th, 30th and 90th postoperative days. During each follow up, UCVA and BCVA were recorded, slit lamp examination was performed; autorefractometry and keratometric examinations were also performed. [b]RESULTS[/b]: Out of 65 in the temporal incision group only 55 completed follow up till 90th day. The mean surgery induced astigmatism was found to be 1.45 ± 0.4 D in superior and 0.70 ± 0.3 D in the temporal incision group. Amount of surgery induced astigmatism was found to be significantly lower among the temporal incision group (t = 11.444, p = 0.000). [b]CONCLUSION:[/b] SICS through temporal approach provides a better stabilization of refraction with significantly lesser amount of SIA than superior approach
