Abstract :
OBJECTIVE: To compare surgically induced postoperative astigmatism results between superior and temporal clear corneal incisions phacoemulsification SETTING: Tertiary eye care center at asram medical college hospital. PATIENTS AND METHODS: This prospective randomised clinical study comprised 100 eyes with grade2 to 3 nuclear cataract (LOCS III classification) who were randomly assigned to two groups of 50 eyes each. Group A underwent superior and group 2 underwent temporal clear corneal approach in phacoemulsification. The patients were examined on day 1, 1week, 1month and 6 weeks postoperatively. Surgically induced astigmatism (SIA) was calculated using vector method. RESULTS: Out of 50 patients in Group A– 30% developed WTR astigmatism with a mean astigmatism of 1.18D and 56% developed ATR astigmatism with a mean astigmatism of 1.13D, 14% had no SIA. In Group B– 50% developed WTR astigmatism with a mean astigmatism of 1.14D and 22% developed ATR astigmatism with a mean astigmatism of 0.91D, 28% had no SIA. The average surgically induced astigmatism in patients who underwent phacoemulsification with PC IOL with superior clear corneal incision was 0.99 D and 0.75 D with temporal clear corneal incisions. The difference between the two groups was statistically significant (p value= 0.024, chi–square). By 6 weeks, 96% eyes in both groups had visual acuity between 6/12 to 6/6. CONCLUSION: The average surgically induced astigmatism is less with temporal clear corneal incision as compared to superior clear corneal incision phacoemulsification with foldable intraocular lens implantation.
