Clinical Trial: Volumetric Visual Fields at Intermediate and Near Distances in Presbyopic Patients Using Occupational and General-Purpose Progressive Addition Lenses

U.S., June 2 -- ClinicalTrials.gov registry received information related to the study (NCT07617090) titled 'Volumetric Visual Fields at Intermediate and Near Distances in Presbyopic Patients Using Occupational and General-Purpose Progressive Addition Lenses' on May 14.

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 Zoom 1.5 FWD 4 m and Vimax PC 1.5 FWD 4 m 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 extent of clear...
