Clinical Trial 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.


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.

Age group 18 Years to 35 Years
Eligibility Inclusion Criteria: - They are between 18 and 35 years of age (inclusive). - 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 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.
