ARTICLE Effectiveness and safety of femtosecond laser–assisted lens fragmentation and anterior capsulotomy versus the manual technique in cataract surgery Kasu Prasad Reddy, MB, DO, MRCOphth(UK), Jochen Kandulla, PhD, Gerd U. Auffarth, MD, PhD, FEBO PURPOSE: To evaluate the effectiveness and safety of cataract surgery using femtosecond laser–assisted lens fragmentation and anterior capsulotomy versus manual cataract surgery. SETTING: MaxiVision Eye Hospital, Begumpet, Hyderabad, India. DESIGN: Randomized controlled open-label multisurgeon prospective trial. METHODS: Patients (at least 18 years old) were randomized to femtosecond laser–assisted lens prefragmentation and capsulotomy or manual capsulorhexis and standard phacoemulsification. Measured outcomes were effective phacoemulsification time (EPT), surgeon-assessed ease of phacoemulsification, mean phaco energy, mean phaco time, balanced salt solution volume, capsulotomy precision, and adverse event rates. RESULTS: Fifty-six eyes had the femtosecond laser procedure, and 63 had manual cataract surgery. The mean EPT was significantly lower in the laser group (5.2 seconds G5.7 [SD]) than in the manual group (7.7 G 6.0 seconds) (P Z.025). There was a significant difference in the mean phaco energy between the 2 groups (13.8% G 10.3% in laser group; 20.3% G 8.1% in manual group) (P.001). There were no significant between-group differences in the ease of phacoemulsification, mean phaco time, or balanced salt solut
