Study Details

Study Description

Brief Summary

The aim of this work is to investigate the clinical performance and subjective acceptance of the comfilcon A asphere contact lens when compared to single-vision spectacles in subjects who have never worn contact lenses and who use digital devices (such as phones, tablets, laptops, desktop computers) for at least 4 hours per day on at least 5 days per week.

Detailed Description

The aim of this clinical work is to compare the clinical performance and subjective acceptance of comfilcon A asphere contact lens when compared to single-vision spectacles in subjects who use digital devices (phones, tablets, laptops, desktop computers) for at least 4 hours per day on at least 5 days per week. Subjects will be randomized to use either their habitual spectacles or the study contact lenses for two months.

    • They are willing and able to follow the protocol.

    • They are a 'neophyte' (i.e. someone who has not worn contact lenses previously, with the exception for the purposes of a trial fitting, lasting up to one week).

    • They have a contact lens spherical prescription between -1.00 to -6.25D (inclusive) based on the ocular refraction.

    • They have a cylindrical correction of -0.875DC or less in each eye based on the ocular refraction

    • They own and habitually wear single vision spectacles used for both distance and near vision, including computer and digital device use.

    • Their single vision spectacles have a mean sphere equivalent within ±0.50D of that of the refraction found in the study for each eye (after having taken lens effectivity into account).

    • They are willing to be fitted with contact lenses and understand they may be randomized to either group.

    • They are willing to wear the contact lenses (if relevant) or spectacles for at least 8 hours per day, 5 days per week.

    • They typically use digital devices for a minimum of 4 hours per day, 5 days per week.

    • They agree not to change the spectacles they will wear for digital device use for the duration of the study.

    • They agree not to participate in other clinical research for the duration of the study.

    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 are using any topical medication such as eye drops (including comfort drops) or ointment on a regular basis.

    • The spectacles they use for digital device viewing on the study have been made with specialist features for computer use, digital eye fatigue or are multifocal/bifocal.

    • They are aphakic.

    • 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 breastfeeding.

    • 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 evidence of a heterotropia or decompensating heterotropia on cover test.

    • They have a history of having been prescribed prism in their spectacles (by self report).

    • They have taken part in any other contact lens or care solution clinical trial or research, within two weeks prior to starting this study.
