ABSTRACT
PURPOSE:
To report intraoperative performance and postoperative outcomes of femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification (PE) in the hands of junior surgeons.SETTING:
Iladevi Cataract & IOL Research Centre, Ahmedabad, Gujarat, India.DESIGN:
Prospective single-masked randomized controlled trial.METHODS:
320 eyes (320 patients) undergoing cataract surgery for uneventful cataracts in the hands of junior surgeons were randomized to Group 1-FLACS or Group 2-PE. Intraoperatively, cumulative dissipated energy (CDE) and fluid used were compared. Postoperatively, the following were compared central corneal thickness (CCT) on day 1, 1 week, and 1 month; corneal clarity (day 1 and 1 week); anterior chamber inflammation (day 1 and 1 week); change in endothelial cell density (ECD) at 6 months postoperatively; and corrected distance visual acuity (CDVA) at 1 week and 1 month postoperatively.RESULTS:
157 and 158 patients in groups 1 and 2 analysed. Intraoperatively, CDE (5.41 ± 2.73 vs 8.83 ± 4.28 in Groups 1 and 2, P = .0001) and fluid used (79.33 ± 33.46 vs 101.82 ± 32.23 mL in Groups 1 and 2, P < .0001) were significantly lesser in Group 1. CCT was significantly higher in Group 2 on day 1 (550.96 ± 33.64 vs 587.70 ± 55.76 µm in Groups 1 and 2, P < .0001) and at 1 week postoperatively (527.94 ± 30.78 vs 545.11 ± 35.17 µm in Groups 1 and 2, P = .001). 72% of eyes had clear corneas on day 1 in Group 1 compared with 39% in Group 2 ( P = .01). Anterior chamber inflammation and CDVA were comparable. Change in ECD was significantly lower (9.3%) in Group 1 vs 12.7% in Group 2, P < .0001.CONCLUSIONS:
FLACS showed lower intraoperative CDE, fluid usage, lesser increase in CCT, better early postoperative corneal clarity, and lesser change in ECD at 6 months postoperatively in the hands of junior surgeons during standard cataract surgery.
