Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
comfilcon A toric
Arm Description
Participants are habitual toric lens wearers and will be fitted with comfilcon A toric lenses.
Outcomes
Primary Outcome Measures
Overall Comfort
Subjective ratings for overall comfort for habitual lenses assessed 2 weeks prior to baseline and for comfilcon A lenses assessed at baseline and 2 weeks post baseline. Scale 0-100, 0=cannot be worn, causes pain, and 100=cannot be felt ever.
Overall Vision
Subjective ratings for overall vision for habitual lenses assessed 2 weeks prior to baseline and vision for comfilcon A assessed at baseline and 2 weeks post.Scale 0-100, 0=Extremely poor vision all of the time, cannot function, 100=Excellent vision all of the time.
Handling
Subjective ratings for handling for habitual lenses assessed 2 weeks prior to baseline and handling for comfilcon A assessed at baseline and 2 weeks post baseline. Scale 0-100, 0=Very difficult, 100=Very easy
Overall Satisfaction
Subjective ratings for overall satisfaction for habitual lenses assessed 2 weeks prior to baseline and overall satisfaction for comfilcon A assessed at baseline and 2 weeks post baseline. Scale 0-100, 0=Extremely dissatisfied, 100=Extremely satisfied.
Lens Fit - Rotation
Lens Fit (rotation) for habitual lenses were assessed 2 weeks prior to baseline and then refitted with comfilcon A lenses. After refitting with comfilcon A, lens fit rotation was assessed at baseline and 2 weeks. Lens rotation was measured within 10 degrees of the desired 6 o'clock position. Scale 0-180 degrees, 0=no rotation, 180=max rotation.
Lens Fit - Overall Stability

Anterior Ocular Health - Palpebral Hyperemia and Roughness
Palpebral hyperemia and roughness for comfilcon A lenses assessed at baseline and 2 weeks. Scale 0-4, 0=None, 4=Severe
Anterior Ocular Health - Bulbar and Limbal Redness
Bulbar and limbal redness for comfilcon A lenses assessed at baseline and 2 weeks. Scale 0-4, 0=None; 4=Severe injection
Anterior Ocular Health - Corneal Staining
Corneal staining for comfilcon A lenses assessed at baseline and 2 weeks. Scale 0-4, 0=No staining; 4= >45% of area
Anterior Ocular Health - Conjunctival Staining and Indentation
Conjunctival staining and indentation for comfilcon A lenses assessed at baseline and 2 weeks. Conjuctival staining scale 0-4, 0=None, 4=Severe
Visual Acuity
Visual acuity for habitual lenses assessed 2 weeks prior to baseline and for comfilcon A assessed at baseline and 2 weeks post baseline using logMAR.
Subjective Preference - Comfort
Subjective preference for comfort between habitual lenses and comfilcon A lenses assessed at baseline and 2 weeks. Preference choices: Prefers comfilcon A lenses, No preference, Prefers habitual lenses
Preference - Vision
Subjective preference for vision between habitual lenses and comfilcon A lenses assessed at baseline and 2 weeks. Preference choices: Prefers comfilcon A lenses, No preference, Prefers habitual lenses
Preference - Handling
Subjective preference for handling between habitual lenses and comfilcon A lenses assessed at baseline and 2 weeks. Preference choices: Prefers comfilcon A lenses, No preference, Prefers habitual lenses
Overall Preference
Overall subjective preference between habitual lenses and comfilcon A lenses assessed at baseline and 2 weeks. Preference choices: Prefers comfilcon A lenses, No preference, Prefers habitual lenses
Investigator Acceptability
Investigator's preference on acceptability of refitting subjects in to comfilcon A lens based on lens performance assessed at baseline and 2 weeks.Scale 1-5, 1=Strongly agree, 5=Strongly disagree.
