Results The mean change in logMAR best-corrected visual acuity from baseline at the long-term post-implantation follow-up visit was 0.01, 0.04, and -0.01 in the AcrySof, silicone, and PMMA groups, respectively. The upper limit of 97.5% one-sided confidence interval of the difference in the change in best-corrected visual acuity between the AcrySof group and each control group was +0.01 logMAR for the silicone group and +0.07 logMAR for the PMMA group, both of which were lower than the non-inferiority margin of +0.1 logMAR.

Other related information Prospective adverse events were observed in the target eye for efficacy analysis of 1 subject (3.2%) in the AcrySof group and in the contralateral eye of 1 subject (3.3%) in the PMMA group. None of these events were considered to be related to the IOL.
Retrospective adverse events were observed in 1 subject (3.2%) in the AcrySof group, 3 subjects (8.1%) in the silicone group, and 4 subjects (13.3%) in the PMMA group. None of these events were considered to be related to the IOL.
A retrospective adverse reaction was observed in 1 subject (2.7%) in the silicone group. The causal relationship between this event and the IOL was considered unknown by the investigator, and the event was therefore classified as an adverse reaction.
No device failures were observed.
