Abstract Details

Purpose:

To compare between Femtosecond Laser Assisted Cataract Surgery (FLACS) and Conventional Phacoemulsification in post vitrectomized eyes

Setting:

Dr R P Centre, AIIMS, New Delhi

Methods:

One group underwent standard phacoemulsification (control group) and the other group underwent FLACS (study group), both with intraocular lens implantation. Pulsed ultrasound energy was used for phacoemulsification using Centurion machine and balanced 45 degree ABS phaco tip. FLACS was performed using LenSx platform. Intra-operative phaco energy (CDE) was noted. Visual acuity, Non-contact endothelial cell microscopy, corneal pachymetry were performed preoperatively and 1 day, 1 week, 1 month and 3 months postoperatively

Results:

The mean phaco energy used was 15.83 ± 13.17 (SD) percent seconds in the control group and 8.11 ± 6.42 percent seconds in the study group. The mean endothelial cell loss was 9.08% ± 3.5% (SD) 1 week postoperatively and 11.94% ± 8.7% 3 months postoperatively in the control group and 4.46% ± 2.6% and 5.35% ± 3.19%, respectively, in the study group. The mean change in corneal thickness from the preoperative values was 1.89% at 1 day, 1.42% at 1 week in the control group and 0.78% at 1 day, 0.65% at 1 week, respectively, in the study group

Conclusions:

The FLACS had significantly lesser intra-operative energy use leading to lesser endothelial damage and decreased post-operative corneal edema compared to the conventional phacoemulsification. This might be beneficial in eyes with low preoperative endothelial cell values like post vitrectomized eyes
