Abstract Details

Purpose:

The aim of this study was to compare the efficacy of laser-assisted cataract surgery (LACS) when lens fragmentation is performed before or after capsulotomy.

Setting:

Oftalvist CIO Jerez, Jerez de la Frontera, Spain

Methods:

LACS was performed with the Centurion Vision System (Alcon, Fort Worth, Texas) and a low energy femtosecond laser (LDV Z8, Ziemer Ophthalmic Systems AG, Port, Switzerland). There were two groups in this study: 21 eyes underwent LACS in which the lens fragmentation was performed before capsulotomy. In other 21 eyes, lens fragmentation took part after capsulotomy. Once surgery was completed, cumulative dissipated energy (CDE), ultrasound (U/S) total time, total aspiration time (TAT), and estimated fluid usage (EFU) were evaluated in both groups and compared against each other.

Results:

Data were first tested for normality using a Shapiro-Wilk test and since the data were found not to be normally distributed, a Wilcoxon signed rank test was performed. The mean difference in CDE, U/S, TAT, and EFU between performing lens fragmentation first and using capsulotomy first was −1.71±4.99 (p = 0.181), −6.05±17.51 (p = 0.211), 0.67±41.40 (p = 0.862), and 0.67±11.62 (p = 0.861), respectively. No significant differences were found in any of the parameters assessed.

Conclusions:

Performing lens fragmentation before or after capsulotomy in LCAS with a low energy femtosecond laser does not seem to have a significant effect on energy, time, or fluid usage in this type of procedures.
