Simultaneous bilateral versus sequential bilateral cataract surgery: Helsinki Simultaneous Bilateral Cataract Surgery Study Report 1.

摘要

PURPOSE: To evaluate the refractive outcomes, complication rates, and changes in patients' functional state and satisfaction with simultaneous compared with sequential bilateral cataract surgery. SETTING: Helsinki University Eye Hospital, Helsinki, Finland. DESIGN: Clinical trial. METHODS: Consecutive patients scheduled for bilateral cataract surgery were enrolled based on appropriate inclusion criteria and randomized to be operated on in 1 session (study group) or sequentially (control group) 4 to 6 weeks apart. RESULTS: Four hundred ninety-one (94.4%) of the 520 patients completed the study. Of the eyes, 493 (247 patients) had bilateral surgery in 1 session and 506 (257 patients) in separate sessions. In the study group, 240 patients (96.0%) were treated per protocol. In the control group, 250 patients (97.3%) were treated per protocol. The refraction was within +/- 0.50 diopter (D) of the target in 67.2% of eyes in the study group and 69.2% of eyes in the control group and within +/- 1.00 D in 91.0% and 90.3%, respectively (P = .92). The only complication that affected postoperative visual acuity was chronic cystoid macular edema, which occurred in 1 eye in the study group (0.2%) and in 2 eyes (0.4%) of 1 patient in the control group (P = .57). Ninety-five percent of patients in both groups reported being very satisfied with surgery. CONCLUSION: The refractive outcomes, rates of complications, and patient-rated satisfaction were similar whether bilateral cataract surgery was performed simultaneously or sequentially.
