Study summary

The purpose of this study is to compare the long-term visual acuity (VA) with an acrylic IOL to a silicone or polymethylmethacrylate (PMMA) IOL in cataract patients. This study will take place in Japan.

What researchers measure

Primary outcomes

  1. Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) at the Long-Term, Post-Implantation Visit

    Measurement of best corrected (with spectacles or other visual corrective devices) visual acuity (at both near and distance). Visual Acuity (VA) is measured in logMAR (logarithm of the minimum angle of resolution). A lower logMAR value indicates better visual acuity. One eye (study eye) contributed to the analysis.

    Time frame: Baseline (up to and including 3 months after implantation), long-term post-implantation visit (14-20 years after implantation)

Adverse events

Collected over Adverse events (AEs) were collected for the duration of a subject's participation in the study; retrospectively 14 to 20 years and prospectively for a single visit. This analysis group includes all subjects who used the study devices and underwent the long-term post-implantation visit examination. Ocular adverse events are presented for both study eye and non-study eye combined.. Non-serious events are listed at a 5% frequency threshold.
