To assess safety and efficacy of a cohort undergoing LCS and to discuss techniques to improve surgical and visual outcomes.
We retrospectively assessed the initial 1500 consecutive cases by all surgeons across various safety parameters.
We compared the initial 200 eyes (group 1) with the following 1300 eyes (group 2) across all parameters. Groups were comparable for baseline demographic parameters. Anterior capsule tears occurred in 4% and 0.31% eyes; posterior capsule tears in 3.5% and 0.31% eyes; and posterior lens dis-location in 2% and 0% eyes in group 1 and group 2 respectively (p < 0.001 for all comparisons). No differ-ence was observed in complication rates in group 2 between surgeons with and without prior experience with a refractive FS laser (p = 0.860, 0.237 and 1.000 respectively). Number of docking attempts per case (1.5 vs. 1.05), incidence of post-laser pupillary con-striction (9.5% vs. 1.23%) and anterior capsular tags (10.5% vs. 1.61%) were significantly lower in group 2 (p < 0.001 for all comparisons). Conclusion: Early results suggest that there is a learning curve associated with the introduction of new technology. Experience combined with surgeon-driven software changes have markedly reduced the inci-dence of complications and laser assisted cataract removal appears as safe, if not safer, than manual surgery.
