Abstract :

 Aim:To analyze the postoperative astigmatism after phacoemulsification and intraocular lens implantation through a superior vs. temporal clear corneal incision. Methods: This prospective observational study included 85 patients. A superior clear corneal incision was made in 42 eyes and a temporal incision in 43 eyes, for phacoemulsification using 3 mm incision. The keratometry reading taken in the preoperative assessment by a Bausch and Lomb keratometer was compared to the values on day 1, week 1 and 6 weeks postoperatively to assess the change in astigmatism(if any). Results: Surgically induced astigmatism was <0.5 Diopters in 93.02% cases in the temporal group, whereas in the superior group it was 83.81%. Conclusion: The temporal clear corneal incision group had statistically significant lower induced astigmatism. It gives a substantial improvement in surgical exposure, especially in those with deep set eyes or prominent eyeows
