Abstract

Purpose: : To assess clinical outcomes in laser cataract surgery when compared to conventional phacoemulsification.

Methods: : Patients electing to undergo routine cataract surgery were recruited onto this study after explanation of the study aims and signing the Ethics Committee approved informed consent. The eye with the most visual compromise was operated on first using the laser procedure. Laser capsulotomy with or without lens fragmentation was followed by cataract surgery using the minimum phaco energy required to aspirate the lens. The fellow eye was subsequently operated on using standard phacoemulsification surgery to act as a control. Standard clinical measures were used to assess patient outcomes.

Results: : 60 laser treated eyes and 45 conventionally treated fellow eyes were included in the analysis. At 3 months postoperative logMAR UCVA was 0.30±0.20 and 0.23±0.16 and logMAR BCVA was 0.05±0.10 and 0.03±0.05 for laser and control eyes respectively. IOP was 14mm±2 Hg for both groups at baseline and was 13±2mmHg at 3 months. 3 eyes in the laser group and 4 eyes in the control group had pressures over 25mmHg at 1 day post-operatively, resolving by 1 week. 4 eyes in each group had a rise in IOP of >10mmHg at day 1 resolving by 1 week. Corneal thickness was 548±38um and 542±57um at baseline and 531±37um and 529±45um at 3 months postoperative for laser and control groups respectively.

Conclusions: : Early clinical data suggest that outcomes with laser cataract surgery show no significant differences in clinical outcomes. If the intended benefits of laser cataract surgery (which include more consistent capsulotomies and reduced phaco energy during lens extraction) can be realized, it appears there will be no adverse effects on clinical outcomes.
