A Comparative Cohort Study of Visual Outcomes in Femtosecond Laser-Assisted versus Phacoemulsification Cataract Surgery.

摘要: Purpose To evaluate visual outcomes after femtosecond laser-assisted cataract surgery (LCS) with phacoemulsification (PCS). Design Prospective, multicenter, comparative case series. Participants Consecutive patients undergoing LCS or PCS intraocular lens insertion. Methods A total of 1876 eyes 1238 (422 male and 772 female) who underwent between January 2012 June 2014 were included in the study: 1017 from center 859 B. Cases clinico-socioeconomic selection. Patients absolute contraindications assigned to PCS; otherwise, all offered elected on basis their decision pay (the out-of-pocket cost for LCS). Demographic postoperative data collected determine differences groups. Main Outcome Measures Six-month refractive outcomes. Masked subjective refractions performed 2 6 months postoperatively. Results There 988 group 888 group. Baseline best-corrected acuity (BCVA) was better compared (20/44.0 vs. 20/51.5; P  = 0.0003) a greater proportion cases achieving BCVA >20/30 (LCS 89.7% 84.2%; 0.0006) 20/40 96.6% 93.9%; 0.0077). However, had more letters gained (13.5 12.5 letters; 0.0088), reflecting baseline differences. Mean error higher (0.41 diopters [D] 0.35 D; Conclusions Femtosecond did not demonstrate clinically meaningful improvements over conventional PCS.
