Trial Outcomes & Findings for Silicone Hydrogel Soft Contact Lens 7-Day Extended Wear Basis (NCT NCT02939950)

NCT ID: NCT02939950

Last Updated: 2019-12-23

Results Overview

For determination of high contrast visual acuity (VA), the participant was seated at the photoropter so that the distance from the participant's eyes to the logMAR chart was 6.5 feet (2.0 meters). The chart was at eye level for each participant. The logMAR charts had two alternative letter sequences from 28 letters (0.3 logMAR) to 62 letters (-0.3 logMAR). The visual acuity was measured through the phoropter using the distance refractive correction with the addition of +0.50 Diopter to compensate for the reduced test distance of 6.5 feet (2.0 meters). A scoring sheet for each eye was provided to keep track of the letters correctly identified by the participants. Scores were recorded as the numbers of letters correctly identified in the eye examination. VA was converted to the Log10 of the Minimum Angle of Resolution (logMAR) by using the score (number of letters).

Participant Flow

A total of 1632 eyes from 816 study participants were enrolled, of which 1612 eyes from 806 study participants were randomized into 1:1 to wear either the Bausch + Lomb samfilcon A soft contact lens or Bausch + Lomb pure vision soft contact lens.

Measure
Bausch + Lomb Samfilcon A Soft Contact Lens
Participants wore Bausch + Lomb samfilcon A soft contact lens in each eye on a 7-day extended daily wear basis for a period of 12 months. The lenses were worn overnight for up to 6 consecutive nights per week. The lenses were removed, cleaned, and disinfected with Biotrue multi-purpose solution on the seventh night and re-inserted the following morning. The lenses were replaced with new lenses on the first monday of each month.
Bausch + Lomb Pure Vision Soft Contact Lens
Participants wore Bausch + Lomb pure vision soft contact lens in each eye on a 7-day extended daily wear basis for a period of 12 months. The lenses were worn overnight for up to 6 consecutive nights per week. The lenses were removed, cleaned, and disinfected with Biotrue multi-purpose solution on the seventh night and re-inserted the following morning. The lenses were replaced with new lenses on the first monday of each month.

Population: Safety analysis set included all dispensed participants.

An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse events were defined as those events that resulted in, or had the potential to cause, either permanent impairment of an ocular function or damage to an ocular structure, and might necessitate medical or surgical intervention. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in reported AE section.
