NCT07595432
The Purpose of This Clinical Study is to Evaluate Optimized Maximum Plus for Maximum Visual Acuity (MPMVA) Refractive Technique and Its Effect on Visual Performance.
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).
