Study Groups

galyfilcon A prototype lens / lotrafilcon B lens

The galyfilcon A prototype lenses will be worn during the first period and lotrafilcon B lenses will be worn during the second period. Each period consists of daily lens wear for one week.

Eligibility Criteria

Inclusion Criteria

1. The subject must be at least 18 years of age and no more than 39 years of age.

2. The subject is a current spherical soft contact lens wearer (defined as a minimum of 6 hours of 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.

3. The subject's optimal vertexed spherical equivalent distance correction must be between -1.00 and - 9.00D.

4. Any cylinder power must be ≤ -0.75D.

5. The subject must have visual acuity best correctable to 20/25+3 or better for each eye.

6. The subject must read and sign the Statement of Informed Consent.

7. The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.

Exclusion Criteria

1. Ocular or systemic allergies or disease which might interfere with contact lens wear.

2. Systemic disease or use of medication which might interfere with contact lens wear.

3. 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.

4. Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear.

5. Any ocular infection.

6. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.

7. Pregnancy or lactation.

8. Diabetes.

9. Infectious diseases (e.g. hepatitis, tuberculosis) or an immuno-suppressive disease (e.g. HIV).

10. Habitual contact lens type is toric, multifocal, or is worn as extended wear.
