Abstract

Impact of Capsulorhexis Morphology on the Predictability of Intraocular Lens Power Calculations

Purpose: To study the impact of capsulorhexis (CCC) morphology on predictability of intraocular lens (IOL) calculations. Setting: Private group ophthalmology practice. Study Design: Non-randomized, masked, retrospective study. Methods: 175 random cataract surgery videos (acrylic IOL) were reviewed (observer masked). CCC morphology in relation to the IOL was graded. Haigis and SRK-T formulae were used to determine IOL power. Prediction errors (1 month refraction) were calculated and variances analyzed. Results: Mean prediction errors were +0.24+0.50D (Haigis) and +0.25+0.47D (SRK-T). The “worst” CCC group had the lowest mean prediction error (p=0.01). No statistically significant difference in variance was identified. Conclusion: Within the range of CCC morphology examined, there appears to be no relationship between CCC morphology and IOL calculation predictability.
