Connecting Contact Lenses and Digital Technology

Asthenopia Clinical Trial

Official title: Connecting Contact Lenses and Digital Technology

Status Completed

Clinical Trial Summary

This study seeks to address whether or not different types of daily disposable soft contact lenses may be a beneficial option for patients complaining of eye strain and visual discomfort while using digital devices.

Clinical Trial Description

This was a prospective, single site, randomized, double-masked, crossover pilot study. Subjects were randomized to begin with either multifocal or single vision distance contact lenses. The lenses used in this study were the 1-Day Acuvue (AV) Moist spherical single-vision soft contact lenses (SSCL) in the 8.5 base curve and the 1-Day AV Moist Multifocal (MFSCL) in the low ADD (etafilcon A, 58% water content). The preferred viewing distance on digital devices for a similar age group to our study was 63 cm which would require a near ADD of +1.59D. A low addition (ADD) yielding up to +1.25D was selected to provide an intermediate near addition without compromising distance vision as much as would be expected with higher add powers. The multifocal lens utilizes an aspheric center-near design. Subjects wore the lenses on a daily wear, daily disposable schedule. Following one week (± 2 days) of lens wear, subjects were evaluated and the alternate lenses dispensed. Adverse events were collected and assessed at each study visit. ;
