Clinical Evaluation of the Safety and Efficacy of a New Multifocal Contact Lens
Study Details
Study Description
Brief Summary
The purpose of this study was to demonstrate substantial equivalence of the new DAILIES® AquaComfort Plus® Multifocal (DACP MF) contact lens to the commercially available Focus® DAILIES® Progressives (FDP) contact lens.

Outcome Measures
Primary Outcome Measures
- Subjective Overall Vision [Up to Day 30]
The participant was instructed to, "Please rate the aggregate of distance, intermediate, and near vision quality. Fill in the circle below the number that indicates your selection. Rate eyes together, marking only 1 circle for both eyes. Higher numbers mean better vision." The response was recorded on a continuous scale from 1-10 (1=poor, 10=excellent).
Secondary Outcome Measures
- Binocular Snellen Visual Acuity (VA) at Distance With Study Lenses [Up to Day 30]
Visual Acuity was tested while reading a chart at 20-foot equivalent distance from the participant with both eyes together. The Snellen fraction compares the participant's result to the result expected from the 'normal' visual system. The numerator represents the distance between the participant and the chart, and the denominator represents the distance at which a person with 'normal' vision would be able to discern the same letter size. 20/20 is considered to be 'normal' vision, whereas visual acuity of 20/40 means the participant is able to read a certain size letter 20 feet away that a person with 'normal' vision would be able to read from 40 feet away. A larger denominator, therefore, indicates a lower visual acuity.
- Binocular Snellen Visual Acuity (VA) at Near (40cm) With Study Lenses [Up to Day 30]
Visual Acuity was tested while reading charts at a distance of 40 cm from the participant with both eyes together. The Snellen fraction 20/20 represents 'normal' near vision. A larger denominator indicates a lower visual acuity.
Eligibility Criteria
