Clinical Validation of DACP Digital Design

May 28, 2019 updated by: Alcon Research
The purpose of this study is to evaluate the visual performance of DAILIES® AquaComfort Plus® (DACP) Digital lenses by assessing distance visual acuity (VA) as compared to DACP sphere contact lenses after one week of wear.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Distance Visual Acuity (VA) (logMAR, OU)
Time Frame: Day 7, each product
VA was tested under photopic (well-lit) conditions using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart positioned 6 meters from the subject. VA was collected bilaterally (OU) and measured in logMAR (logarithm of the minimum angle of resolution), with 0.1 logMAR increment corresponding to 5 letters, or 1 line, on the ETDRS chart. A lower numeric value represents better visual acuity.
Day 7, each product

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Vision
Time Frame: Day 7, each product
Subjective rating of overall vision on a scale of 1 (Poor) to 10 (Excellent). Both eyes contributed to the analysis.
Day 7, each product
