Pilot Evaluation of a New Galyfilcon A Contact Lens Compared to a Marketed Galyfilcon A Contact Lens

Inclusion Criteria: * The subject must be at least 18 years of age and no more than 39 years of age. * The subject is a current spherical soft contact lens wearer (defined as a minimum of 6 hours of daily wear (DW) for a minimum of 1 month prior to the study) and willing to wear the study lenses on a daily wear basis (defined as a minimum of 6 hours of wear per day at least five days of the week) for the duration of the study. * The subject's optimal vertexed spherical equivalent distance correction must be between -1.00 and - 9.00D. * Any cylinder power must be ≤ -0.75D. * The subject must have visual acuity best correctable to 20/25+3 or better for each eye. * The subject must read and sign the Statement of Informed Consent. * The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol. Exclusion Criteria: * Ocular or systemic allergies or disease which might interfere with contact lens wear. * Systemic disease or use of medication which might interfere with contact lens wear. * Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear. * Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear. * Any ocular infection. * Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear. * Pregnancy or lactation. * Diabetes. * Infectious diseases (e.g. hepatitis, tuberculosis) or an immuno-suppressive disease (e.g. HIV). * Habitual contact lens type is toric, multifocal, or is worn as extended wear.
