Clinical Trial: Volumetric Visual Fields at Different Distances in Presbyopic Patients Using Occupational (PC-133 and PC-200) and General-Purpose Progressive Addition Lenses

U.S., Oct. 14 -- ClinicalTrials.gov registry received information related to the study (NCT07870785) titled 'Volumetric Visual Fields at Different Distances in Presbyopic Patients Using Occupational (PC-133 and PC-200) and General-Purpose Progressive Addition Lenses' on Oct. 06.

Brief Summary: This single-center, randomized, double-blind, crossover clinical trial aims to compare the volumetric visual fields provided by two occupational progressive addition lenses (OPLs) optimized for intermediate and near vision in presbyopic patients. The study evaluates Vimax PC 1.5 FWD 133 cm and Vimax PC 1.5 FWD 200 cm lenses and Vimax Fit FRM, all of them with plano distance power and a +2.00 D near addition, in order to determine differences in the e...
