A Range of Contact Lenses and Care System Combinations

Subjects were randomized to wear fanfilcon A soft contact lens in one eye and comfilcon A soft contact lens in the other eye with each lens having been soaked overnight in the Hy-Care contact lens solution and Lite contact lens solution.

Inclusion criteria

• They are of legal age (18) and capacity to volunteer.
• They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent.
• They are willing and able to follow the protocol.
• They agree not to participate in other clinical research for the duration of this study.
• They can be satisfactorily fitted with the study lens for a period of approximately 2 hours.
• They can attain at least 0.20 logMAR distance high contrast visual acuity in each eye with their habitual spectacles.
• They currently wear daily disposable soft contact lenses or have done so in the previous six months.
• They are willing to comply with the wear schedule (approximately 2 hours on two different days)
• They own a wearable pair of spectacles and agree to bring these to study visits.

Exclusion criteria

• They have an ocular disorder which would normally contra-indicate contact lens wear.
• They have a systemic disorder which would normally contra-indicate contact lens wear.
• They currently wear reusable soft contact lenses in both eyes.
• They are using any topical medication such as eye drops or ointment.
• They have had cataract surgery.
• They have had corneal refractive surgery.
• They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
• They are pregnant or breast-feeding.
• They have any ocular abnormality which would, in the opinion of the investigator, normally contraindicate contact lens wear.
• They have Type 2 or greater corneal staining prior to lens application at Visit 1 or 2
• They have corneal staining covering greater than 20% in any corneal region at Visit 1a or 2a
• They have any infectious disease which would, in the opinion of the investigator, contraindicate contact lens wear or pose a risk to study personnel; or they have any immunosuppressive disease (e.g. HIV), or a history of anaphylaxis or severe allergic reaction.
• They have taken part in any other contact lens or care solution clinical trial or research, within two weeks prior to starting this study.
