About this study

Official title: Comparison of a New AMO MPS to Existing Contact Lens Regimens

Crossover clinical evaluation three contact lens care regimens used for one month with Acuvue Oasys lenses.

Read the detailed description

This is a three-arm crossover clinical evaluation of 40 subjects who will use each of three contact lens care regimens for one month with Acuvue Oasys lenses. The subjects will be randomized on the order of solutions used: Investigational MPS, ClearCare, and Opti-Free RepleniSH MPS.

Being tested
Multi-purpose disinfecting solution, Clear Care, Opti-Free RepleniSH

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Clear CareDevice

    Peroxide-based regimen for cleaning and disinfecting soft contact lenses.

  • Opti-Free RepleniSHDevice

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Corneal Staining

    Corneal staining will be assessed with sodium fluorescein dye on the ocular surface. The cornea is split into 5 sections, each section is evaluated by staining type, depth, and extent is graded on a 0 to 100 scale with higher scores indicating more staining. The possible total range for the total score per eye is 0 to 50,000 (100x100x100=10,000 per section) with values higher than 1200 being clinically relevant.

    Measured: 4 weeks

Secondary outcomes (2)
  1. Subjective Lens Wearing Comfort

    This will be assessed by a questionnaire on patient-perceived lens comfort and any symptoms of discomfort on a 0 to 100 scale.

    Measured: 4 weeks

  2. Dryness

    This will be assessed by the tear break-up time on the lens surface, measured in seconds.

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Multi-purpose disinfecting solution, Clear Care and Opti-Free RepleniSH in people with Normal Contact Lens Wearers, run by Abbott Medical Optics at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 May 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Corneal Staining (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2017; AzTrials last refreshed its copy on 7 Nov 2026.
