Visual Outcome

This is a prospective, multicenter, parallel groups, non-interventional, examiner masked, comparative clinical study. Patients that participated in previous Hoya studies, and patients previous implanted with Hoya non-toric monofocal IOLs (sub-study only) will be enrolled in the study. The sample size for this study is based on demonstrating the non-inferiority of the mean distance-corrected intermediate visual acuity (DCIVA) in Group 1 (Site 1) compared with Group 2 (Site 2).

The purpose of this study is to evaluate the long-term visual outcome of the cataract surgery using a large-scale and comprehensive database of high myopic cataract and age-related cataract patients. The investigators will further investigate into the various genetic and environmental factors that may contribute to the pathogenesis of high myopic cataract.

The purpose of this study is to evaluate the long-term visual outcome of the cataract surgery using a large-scale and comprehensive database of pediatric cataract participants, including congenital and traumatic cataract. The investigators will further investigate into the various genetic and environmental factors that may contribute to the pathogenesis of pediatric cataract.
