- Refractive Errors
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lens A (ocufilcon D)Device
15 minutes of daily wear.
Lens B (fanfilcon A)Device
15 minutes of daily wear.
| Study group | Role | What they receive |
|---|---|---|
| Lens A (ocufilcon D) | Experimental | All participants will wear lens A for 15 minutes (Period 1). Receives: Device: Lens A (ocufilcon D) |
| Lens B (fanfilcon A) | Experimental | All participants will wear lens B for 15 minutes (Period 2). Receives: Device: Lens B (fanfilcon A) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Lens Fit Acceptance Ratings
Overall lens fit acceptance was measured on a scale from 0-4 (0=Should not be worn and 4= Perfect)
Measured: At the end of 15 Minutes of wear
