Initial Performance of a Daily Disposable Contact Lens Featuring Molded Marks

Not Applicable

Completed

Interventions: Device: Delefilcon A Multifocal Contact Lenses with Molded Mark
Device: Delefilcon A Multifocal Contact Lenses

Brief Summary: The purpose of this study is to evaluate the impact of back surface molded marks (MM) applied to delefilcon A contact lenses as measured by the incidence of ocular discomfort device-related adverse events with DAILIES TOTAL1® Multifocal contact lenses with molded marks (DT1 MF MM) and current DAILIES TOTAL1® Multifocal contact lenses (DT1 MF).

Arm && Interventions

Group	Intervention	Description
DT1 MF MM	Delefilcon A Multifocal Contact Lenses with Molded Mark	Delefilcon A multifocal contact lenses with molded marks on back surface worn bilaterally (in both eyes) for 9 hours
DT1 MF	Delefilcon A Multifocal Contact Lenses	Delefilcon A multifocal contact lenses worn bilaterally for 9 hours

Primary Outcome Measures

Name	Time	Method
Incidence of Ocular Discomfort Device-related Adverse Events (AE)	Day 1 at Hour 9	An AE was defined as any untoward medical occurrence, unintended disease or injury, or untoward clinical signs in subjects, users or other persons, whether or not related to the investigational medical device (test article). Ocular discomfort device-related AE was defined as an ocular AE classified as "Related" to study device and deemed to be related to ocular discomfort.

Secondary Outcome Measures

Name	Time	Method
Ocular Staining	Day 1 at Hour 9	Assessed by the Investigator through slit-lamp examination and graded on a 5-point scale, where 0=none and 4=severe. Ocular staining was categorized by corneal staining, conjunctival staining, and limbal staining. Both eyes contributed to the analysis.
Limbal Hyperemia	Day 1 at Hour 9	Hyperemia (excess of blood) was assessed by the Investigator through slit-lamp examination and graded on a 5-point scale, where 0=none and 4=severe. Both eyes contributed to the analysis.
