Abstract

Purpose: To investigate if the larger capsulorhexis (7mm) is associated with a stable post-operative refraction with Acrysof IQ one-piece IOL (SN60WF, Alcon USA) implantation from 1month to 2 years after cataract surgery. Method: Retrospective chart review was made on 31 eyes of 20 patients. All eyes had uncomplicated phacoemulsification by the author with 7mm capsulorhexis and Acrysof one-piece IOLIQ (SN60WF, Alcon USA) implantation between 4/2007 and 7/2008. IOL Master was used to select the IOL and target refraction was recorded. Refraction data by manifestation in spherical equivalent (SE) at one month, 3 month and 2 years were recorded and input to SPSS19. Result: The mean refractions in spherical equivalent (SE) were statistically significant and excellent positively correlated among the preoperative target refraction (IOL master), one month post-op, three months post-op and two years post-op. P<0.01, Pearson correlation coefficient: r>+0.9 (95%CI 0.91 to 0.98) Conclusion: The 7mm capsulorhexis with Acrysof one-piece IOLIQ (SN60WF, Alcon USA) implanted eyes demonstrated refractive stability from 1 month up to 2 years post operation.
