- Device: Delefilcon A multifocal contact lensesDevice: Etafilcon A multifocal contact lenses
- Registration Number
- NCT03341923
- Lead Sponsor
- Alcon Research
- Brief Summary
The purpose of this clinical study is to evaluate DAILIES TOTAL1® Multifocal (DT1MF) contact lenses compared to 1-DAY ACUVUE® Moist® Multifocal (AMMF) contact lenses for investigator-graded lens centration in a Japanese population.
- Detailed Description
Subjects will be randomly assigned to one of two sequences of investigational product wear ((DT1MF→AMMF, AMMF→DT1MF). Each product will be worn in both eyes for at least 11 days.

- Primary Outcome Measures
Name Time Method Percentage of Subjects With Investigator-graded Lens Centration of "Optimal" Day 14, each product Lens centration was assessed by slit-lamp microscopy and graded on a 5-point scale, where 0=Optimal/Centered and 4=Severe decentration (with corneal exposure). One target eye was randomly selected for analysis.
