Abstract Details

Purpose:

To compare the Nd:YAG posterior capsulotomy rates after Cataract Surgery performed using a femtosecond laser (Lensx) vs Manual technique.

Setting:

Coastal Vision Medical Group, California, USA

Methods:

Retrospective chart analysis study of 1422 eyes that underwent cataract surgery between August 2011 and August 2013. The cases were divided into two groups depending on surgical technique FLACS (n=813) and Manual (n=609). The rate of Nd:YAG posterior capsulotomy was assessed for these two groups, and then stratified by type of IOL implanted (accommodating, monofocal and multifocal).

Results:

The overall YAG rate was 10.4%; when stratified by surgical technique, FLACS rate was lower than Manual surgery (8.8% vs 12.6%). Accommodating IOLs had the highest Nd:YAG rates amongst all IOL groups, and there was no difference by technique (FLACS 20.1%, Manual 21.2%). Patients with multifocal IOLs operated with FLACS (6.2%) had significantly lower YAG rates than Manual (15.4%). Similar situation for Monofocal IOLs (7.4% vs 11.8%).

Conclusions:

Femtosecond laser assisted cataract surgery creates a perfectly round, small, overlapping over the IOL edge, which enhances shrink-wrapping around the IOL, thus reducing the rate of PCO that requires Nd:YAG laser posterior capsulotomy in eyes implanted with IOLs with square edge (multifocal and monofocal IOLs)
