Background and objectives: A cross sectional study was conducted at New Civil Hospital, Surat to evaluate changes in corneal curvature 1,1½ &2 years after on axis phacoemulsification surgery incisions. Method: 50 patients having undergone clear corneal phacoemulsification with astigmatism friendly incisions and foldable intraocular lens implantation 1 to 2 years back with detailed preoperative data were seen. They were grouped as 1(Group A) ,1½(Group B) and 2years (Group C) post surgery follow ups. Their postsurgery corneal curvature and refraction was observed at time of study and was compared to same at 40th day after surgery. Results: Mean post op astigmatism in group A (0.50±0.25), Group B (0.51 ± 0.30) and Group C (0.75±0.29) were observed. The mean change in corneal curvature as compared to baseline was not significant statistically in Group A (p=0.6) and Group B (p = 0.6).In Group C the change corneal curvature of 0.22 D was statistically significant by t tests. The mean change in refraction was not significant statistically in all three groups. Conclusion: Against the rule change in corneal curvature , independent of type of incision seen after 2 years of surgery which can be age related. Thus reassessment of refraction is not required frequently in astigmatism friendly incisions. [Foram D NJIRM 2017; 8(3):75-77]
