Clinical Performance Evaluation of Two Frequent Replacement Silicone Hydrogel Multifocal Toric Contact Lenses

Clinical Performance Evaluation of Two Frequent Replacement Silicone Hydrogel Multifocal Toric Contact Lenses

The purpose of this study is to evaluate on-eye clinical performance of the investigational contact lenses following 30 days of wear in the intended population.

Subjects will wear two different contact lens study products in a cross-over fashion. Each study product type will be worn for approximately 30 days. A washout period of 2-4 days will occur prior to the first wear period and between the two wear periods. Subjects will be expected to attend 5 office visits. The total duration of study participation is approximately 66 days.

Key Inclusion Criteria:

• Habitual wearer of biweekly/monthly replacement soft multifocal or multifocal toric contact lenses in both eyes for a minimum of 5 days per week and 8 hours per day during the past 3 months;
• Manifest cylinder equal to or greater than 0.75 diopter (D) in each eye at Screening;
• Willing to not use readers while wearing study contact lenses for duration of the study;
• Other protocol-defined inclusion criteria may apply.

Key Exclusion Criteria:

• Use of topical ocular medications and artificial tear or rewetting drops that would require instillation during contact lens wear;
• Wears habitual contact lenses in an extended wear modality (routinely sleeping in lenses for at least 1 night per week) over the last 3 months prior to enrollment;
• Monovision contact lens wearers and wearers of contact lens in one eye only;
• Other protocol-defined exclusion criteria may apply.
