Purpose: To evaluate the post-operative changes in astigmatism in Pseudophakic eyes of children using sutured clear corneal incisions.

Methods: The charts of children who underwent surgery for developmental Cataract using clear corneal tunnel incision at 10’O clock and 2’O clock position were retrospectively reviewed. All the sutures from cornea were removed after 1 month of surgery. Refraction was done at 1 month, 3months 6 months and 1 year interval. Statistical analysis was done by SPSS version 16.

Result: With the rule astigmatism was highest in the study cases. By postoperative 1 month, 3 months, 6 months and 1 year, there was a shift to With the Rule Astigmatism with 73.7%, 76.3%, 78.9% and 86.8% of eyes respectively. Astigmatism became stable after 6 months of surgery. There were no significant changes in astigmatism after 6 months or 1 year of surgery.

Conclusion: Clear corneal incision at 10’O clock and 2’O clock did not significantly influence preoperative existing astigmatism. There was no significant change in astigmatism after 6 months & 1 year of surgery.
