Abstract
Introduction: Small incision cataract surgeries may be performed using various surgical incisions,
namely, superior, supero-temporal and temporal. Each method has its own advantages and
disadvantages. Supero-temporal incision is considered the best as it produces least induced astigmatism.
The purpose of this study was to compare the postoperative induced astigmatism in superior and
superotemporal incision group in small incision cataract surgery.
Material &Method- This study was conducted on cataract surgery patients admitted in M.R.A Medical
College, Ambedkarnagar. Fifty patients were selected for study, out of which 30 received superior and
20 received superotemporal incision. Preoperative keratometric and post operative 6 weeks keratometric
readings were analysed.
Results-Superior incision is better for with the rule astigmatism and worst for against the rule
astigmatism, while superotemporal incision is equally good for both with the rule and against the rule
astigmatism.
Conclusion-Superotemporal incision is better than superior as it produces least astigmatism with good
visual acquity.
