About this study

The purpose of this study was to evaluate the clinical performance of three differing contact lens care solutions when used in conjunction with three contact lenses.

Read the detailed description

This study was conducted as three separate studies based on the contact lens brand dispensed. In each study, the contact lens was evaluated in conjunction with three solutions: Opti-Free Replenish, ReNu MultiPlus, and Clear Care. The total enrollment number of 75 represents a combined enrollment of the three studies, with some subjects participating in more than one study.

Conditions
Contact Lenses
Being tested
Opti-Free RepleniSH multi-purpose disinfecting solution, ReNu MultiPlus multi-purpose solution, Clear Care cleaning and disinfecting system, Senofilcon A contact lens (ACUVUE OASYS), Lotrafilcon B contact lens (AIR OPTIX AQUA)

What is being measured

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

  1. Modulus

    Modulus is a measure of the stiffness of a contact lens material. Modulus is determined from the slope of the stress-strain curve created during tensile tests conducted on a sample of the material. Modulus is measured in mega Pascals (MPa). A higher modulus indicates a stiffer contact lens.

    Measured: 2 weeks

  2. Bulbar hyperemia

    Bulbar hyperemia is the injection (or redness) of the blood vessels in the tissues overlaying the white of the eye. Bulbar hyperemia is measured on a 0-4 scale, with 0=none, 1=trace, 2=mild, 3=moderate, and 4=severe. Half-grades are allowed.

    Measured: 2 weeks

  3. Corneal staining type

    An ophthalmic dye is used to highlight dead or degenerated corneal epithelial cells. The type of staining is measured over the five sectors of the cornea on a 0-4 scale, where 0=none, 1=micropunctate, 2=macropunctate, 3=coalesced macropunctate, and 4=patch (1mm). The five sectors are averaged to give a single score.

    Measured: 2 weeks

  4. Upper palpebral roughness

    The roughness of the inner lining of the upper eyelid is measured on a 0-4 scale, where 0=uniform appearance, 1=trace, 2=mild, 3=moderate, and 4=severe. Half grades are allowed.

    Measured: 2 weeks

  5. High contrast visual acuity

    High contrast visual acuity is a measure of the clearness of vision with full room illumination. Visual acuity is measured with a computer-generated, high contrast logMAR (logarithm minimum angle of resolution) chart.

    Measured: 2 weeks

  6. End of day comfort

    As assessed by the subject as a measure of the comfort of the contact lenses at the end of an average day. End of day comfort is recorded on an 11-point scale where 0=poor and 10=excellent.

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Opti-Free RepleniSH multi-purpose disinfecting solution, ReNu MultiPlus multi-purpose solution and Clear Care cleaning and disinfecting system in people with Contact Lenses, run by Alcon Research at 1 site in United Kingdom.

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 6 inclusion and 6 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 16 Nov 2016. 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 United Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Modulus (time frame: 2 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00982046, which also lists 1 linked publication.

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 16 Nov 2016.
