Evaluation of Tangible Boost Replenishing System

Evaluation of Tangible Boost Replenishing System

This study will evaluate Tangible Boost, a new contact lens care product which is designed to replenish the hydrogel layer on fluorosilicone acrylate lenses with Hydra-PEG. The Hydra-PEG coating is a poly(ethylene glycol)-based hydrogel that is covalently bound to the lens surface. This coating improves lens wettability, a common cause of patient discomfort. Tangible Boost is designed to maintain the wettability of Hydra-PEG lenses throughout the lens lifetime. Patients can use the Tangible Boost kit to reapply the Hydra-PEG coating each month at home.

Inclusion Criteria:

• Habitual contact lens wear with a group 3 FDA approved rigid lens material, with 20-50% of subjects wearing corneal lenses
• Willing and able to sign the informed consent form
• 18 years or older

Exclusion Criteria:

• Eye injury or surgery within the 3 months immediately prior to enrollment for this trial
• Pre-existing ocular irritation that would preclude contact lens fitting
• Current enrollment in an ophthalmic clinical trial
• Evidence of systemic or ocular abnormality, infection, or disease which is likely to affect successful wear of contact lenses or use of the accessory solutions, as determined by the investigator
• Any use of medications for which contact lens wear could be contraindicated, as determined by the investigator
• Pregnant women and nursing mothers
• Visual acuity less than 20/20 when best corrected with contact lenses
