Study Details

Study Description

Brief Summary

This study aims to compare the short-term clinical performance of the three contact lenses (Methafilcon A IV, Ocufilcon B 1-day and Omafilcon A 1-day daily disposable).

Condition or Disease Intervention/Treatment Phase
  • Device: Methafilcon A IV
  • Device: Ocufilcon B
  • Device: Omafilcon A

Detailed Description

This will be a randomized, double-masked, crossover, bilateral non-dispensing study, controlled by cross-comparison. Forty subjects will wear each lens brand for approximately one hour, on three separate study days in random order. Lenses will only be worn during study visits.

Outcome Measures

Primary Outcome Measures

  1. Visual Acuity Using logMAR [Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn]

    Assessment of visual performance using the Bailey-Lovie logMAR visual acuity test chart and procedures for carrying out an over-refraction

  2. Lens Fit - Horizontal Centration [Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn]

    Assessment of horizontal centration of lens on eye

  3. Lens Fit - Vertical Centration [Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn]

    Assessment of vertical centration of lens on eye

  4. Lens Fit - Corneal Coverage of Lens [Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn]

    Assessment of corneal coverage of lens on eye

  5. Lens Fit - Movement of Lens [Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn]

    Assessment of movement of lens on eye

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years to 40 Years
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
Yes
Inclusion Criteria:
  • They are of aged 18-40 and have 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 have a contact lens spherical prescription between -1.00 to - 6.00D (inclusive)

  • They have a spectacle cylindrical correction of -0.75D or less in each eye (based on the ocular refraction).

  • They can attain at least 0.10 logMAR distance high contrast visual acuity in each eye with the study lenses within the available power range.

  • They currently use soft contact lenses or have done so in the previous six months.

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 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 lactating.

  • They have any ocular abnormality which would, in the opinion of the investigator, normally contraindicate contact lens wear.

  • 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.
