Investigation of the Clinical Performance of Silicone Hydrogel Contact Lenses During Continuous Wear

The primary purpose of this study is to investigate the clinical performance of a new silicone hydrogel contact lens during continuous wear (up to 30 nights) over a period of 24 months.

Inclusion Criteria:

• Has had an oculo-visual examination in the last 2 years.
• Is correctable to at least 6/7.5 distance visual acuity in each eye with spherical contact lenses.
• Is a current soft contact lens wearer.
• Has no clinically significant anterior eye findings.
• Has no other active ocular disease.

Exclusion Criteria:

• Has any systemic disease that might interfere with contact lens wear
• Is using any systemic or topical medications that will affect ocular health.
• Has any pre-existing ocular irritation that would preclude contact lens fitting.
• Has any ocular pathology or severe insufficiency of lacrimal secretion (dry eyes) that would affect the wearing of contact lenses.
• Has undergone corneal refractive surgery.
• Is pregnant, lactating or planning a pregnancy.
