Session Title: FREE PAPERS

Session Time: 4:00 pm - 5:30 pm

Purpose:
To assess safety and efficacy of a cohort undergoing LCS and to discuss techniques to improve surgical and visual outcomes.

Methods:
We retrospectively assessed the initial 1500 consecutive cases by all surgeons across various safety parameters.

Results:
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.
