Trial Outcomes & Findings for Effect of Contact Lens Wear on Immune Cell Density and Morphology of the Ocular Surface (NCT NCT01250925)

NCT ID: NCT01250925

Last Updated: 2017-01-10

Results Overview

The primary statistical objective is to describe differences in efficacy between regimens, specifically for measures of epithelial immune status. Immune status will be assessed via density of dendritic and non-dendritic immune cells.

Participant Flow

94 Neophyte contact lens wearers were fitted for one of 3 types of contact lenses (Bausch and Lomb PureVision; Vistakon Acuvue Oasys or Cooper Vision Biofinity) and were then randomized into one of three test articles (care regimens): OptiFree RepleniSH Multi-Purpose Disinfecting Solution, Clear Care or ReNu MultiPlus Multi-Purpose Solution.

127 subjects were screened, out of which 94 were successfully enrolled and 35 were screenfailed due to non-normal clinical findings. Of the enrolled, 10 did not complete the study visits.

SECONDARY outcome

Timeframe: Six weeks

Population: Participants who completed the study visits were analyzed.

The safety analysis will be based on slit-lamp findings, corrected visual acuity (Snellen) and adverse events (if any). No inferential statistical analyses are planned for any safety variable.
