Clinical Performance of Two Frequent Replacement Silicone Hydrogel Multifocal Contact Lenses

The purpose of this study is to evaluate the on-eye multifocal clinical performance of investigational LID233309 contact lenses and Oasys multifocal (MF) contact lenses in a daily wear dispensing trial.

Subjects will wear two different contact lens study products in a cross-over fashion. Each study product type will be worn for approximately 14 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 7 office visits. The total duration of study participation is approximately 40 days with approximately 28 days of lens wear.

Key Inclusion Criteria:

• Current wearer of biweekly/monthly replacement multifocal soft contact lenses in both eyes for a minimum of 5 days per week and 10 hours per day during the past 6 months.
• Manifest cylinder equal to or less than 0.75 diopter (D) in each eye.
• Able to wear contact lenses within the available power range with a near ADD of +0.75 D to +2.50 D in each eye.
• Other protocol-defined inclusion criteria may apply.

Key Exclusion Criteria:

• Currently pregnant or lactating.
• History of amblyopia, strabismus, or binocular vision abnormalities.
