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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |

Outcome results
Incidence of Ocular Discomfort Device-related Adverse Events (AE)
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.
