Brief Summary
The objective of the study is to determine if habitual or adapted contact lens wearers of Omafilcon A can be confidently refit into Somofilcon A lenses and be successful after one week of daily wear. The primary outcome variables for this study are:
- Investigator responses to refit questions;
- Lens fit.

Outcome Measures
Primary Outcomes (10)
Investigator Opinion On Overall Patient Refit From Omafilcon A to Somofilcon A: Does Somofilcon A Provides Easy and Quick Refit From Omafilcon A?
Investigator level of agreement using a Likert scale on refitting participants from omafilcon A to somofilcon A at Visit 1 (Strongly Agree, Agree, Slightly Agree, Slightly Disagree, Disagree, Strongly Disagree)
1 week
Investigator Assessment to Refit- Based on the Investigator Opinion and Lens Fit Outcomes, Would the Investigator Refit the Subject Into Somofilcon A From Omafilcon A?
Investigator level of agreement on the ease of refitting participants from omafilcon A to somofilcon A using Likert scale (Strongly agree, Agree, Slightly Agree, Slightly Disagree, Disagree, Strongly Disagree)
1 week
Investigator Assessment to Refit - Does Somofilcon A Performs Better Than Omafilcon A Day?
Investigator level of agreement on the ease of refitting participants from omafilcon A to somofilcon A using Likert scale (Strongly agree, Agree, Slightly Agree, Slightly Disagree, Disagree, Strongly Disagree)
1 week
Investigator Assessment to Refit - Does Somofilcon A Provides an Upgrade From Omafilcon A?
Investigator level of agreement on the ease of refitting participants from omafilcon A to somofilcon A using Likert scale (Strongly agree, Agree, Slightly Agree, Slightly Disagree, Disagree, Strongly Disagree)
1 week
Lens Fit - Post-blink Lens Movement
Graded on a scale of 0-4, 1 step, 0=Insufficient, unacceptable movement, 4=Excessive, unacceptable movement.
Dispense and 1 Week
Lens Fit - Lens Tightness
Graded using 0-100 scale (5% steps) where 0 = extremely loose and 100 = extremely tight.
Dispense and 1 week
Lens Fit - Lens Deposition
Graded on a scale of 0-4, with 0.25 increments, 0=no deposits; 4=deposit ≥ 0.5mm or film \>75% surface.
Dispense and 1 week
Lens Fit - Centration
(3 point scale: optimum, decentration acceptable, decentration unacceptable)
Dispense and 1 Week
Lens Fit - Lens Wettability
Graded on a scale of 0-4 with 0.25 increments, 0=excellent; 4=severely reduced.
Dispense and 1 Week
Overall Lens Fit Acceptance
Graded on a 0-4 point scale (where 0 = should not be worn, 4=perfect), providing a reason if Grade 2 or less
Dispense and 1 Week
