Pak J Med Health Sci Jan ;12(3):1192-4.

Aim: To compare surgically induced astigmatism with injector delivery in AC and in Capsular Bag of intraocular lens after phacoemulsification. Methods: It is Quasi experimental study. It was done at Central Park Teaching Hospital, Lahore. 70 consecutive patients were randomly divided in two groups. Both groups were implanted with foldable Iols with injector. In AC group the lens was deliver in Anterior chamber and in Bag lens was deliver directly in capsular bag by passing the full nozzle through wound in anterior chamber. Pre and postoperative keratometric reading of the patients were taken by Goldman keratometer. Surgically induced astigmatism was calculated by vector method. Results: Mean preoperative astigmatism in AC group was 0.1618(+/-0.1834) and in Bag group was 0.1929+/-0.2107. Post-op first week Ast in AC group was 0.1929+/-0.2193 and in Bag group was 0.2500+/-0.2268. At fourth week Astigmatism in AC group was 0.1857+/-0.2375 and in Bag group, was 0.2286+/-0.1952. AT thirteenth week, Astigmatism in AC group was 0.1714+/-0.1795 and in Bag group was 0.2429+/- 0.1766. Conclusion: Statistically insignificant difference was found between two groups. However, values were more in Bag then the Ac group. Maneuver of delivering the IOL in Ac should be considered during Toric and multifocal IoLs implantation.
