To assess pain perception in patients undergoing manual cataract surgery versus femtosecond laser-assisted cataract surgery (FLACS) and pain perception of patients receiving anaesthesia at 2 different time points during the FLACS procedure. We also aimed to assess the factors affecting pain perception in these different study groups. Prospective cohort comparison of patient-selected surgical approach. Patients undergoing delayed sequential bilateral cataract surgery at an ambulatory surgical centre in Ontario. Patients were assigned to 3 groups: a manual cataract surgery cohort (n = 30) and 2 FLACS cohorts, those who received neurolept anaesthesia just prior to draping for phacoemulsification (FLACS standard cohort; n = 38) and those who received neurolept anaesthesia prior to the femtosecond laser part of the procedure (FLACS early cohort; n = 35). Outcome metrics included pain scores on the visual analogue scale on postoperative day 0 and at postoperative week 1. Secondary outcome measures included anxiety scores, surgeon or anaesthesiologist patient cooperation scores, ocular metrics, and perioperative systemic vitals. There were no significant differences in pain perception on postoperative day 0 and at postoperative week 1 among the manual cataract surgery and FLACS standard cohorts (p = 0.94 and p = 0.72, respectively) or FLACS early and FLACS standard cohorts (p = 0.76 and p = 0.67, respectively). Patients had higher pain scores during second-eye procedures than first-eye procedures. Cataract surgery technique or timing of anaesthesia for FLACS procedures does not affect pain perception postoperatively. Second-eye procedures are associated with higher pain scores than first-eye procedures.
