About this study

The purpose of this study is to evaluate the lipid uptake, wetting characteristics, and visual performance of AIR OPTIX® AQUA and ACUVUE® OASYS® with HYDRACLEAR® contact lenses when used in conjunction with two contact lens care systems.

Read the detailed description

This study will be divided into two phases. In the Pre-Investigational Phase (Phase 1), participants will wear PureVision contact lenses for 30 days and use ReNu® Multiplus® for contact lens care. Eligible participants will continue into the Investigational Phase (Phase 2) and be randomly assigned to wear AIR OPTIX® AQUA contact lenses or ACUVUE® OASYS® with HYDRACLEAR® contact lenses for a total of two months. For contact lens care, participants will use OPTI-FREE® PUREMOIST® MPDS and BIOTRUE® for 30 days each.

What is being measured

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

  1. Mean Ex-Vivo Total Lipid Uptake Per Lens

    The contact lens was aseptically removed from the eye. Lipids were extracted and analyzed using a proprietary High Performance Liquid Chromatography technique. A lower value indicates a cleaner lens surface. One eye (study eye) contributed to the mean.

    Measured: Day 30

Secondary outcomes (6)
  1. Mean Non-Invasive Pre-Lens Tear Film Break Up Time (NIBUT)

    The pre-lens tear film is the layer of tears located on top of the contact lens between the eyelid and the contact lens. NIBUT (i.e., the time elapsed between eye opening after a blink and the appearance of the first dark spot within the tear film) was measured using a diffuse illumination source (Tearscope) and videotography. A longer NIBUT indicates a more stable tear film and greater on-eye lens wettability. One eye (study eye) contributed to the mean.

    Measured: Day 30

  2. LogMAR Time-Controlled Visual Acuity (TCVA)

    Visual performance was measured binocularly (both eyes together) at two contrast levels using a validated Time Controlled Visual Acuity test (TCVA). TCVA was recorded in VA units (1 VA unit=1 VA line=0.1 logMAR), with positive (+) values corresponding with VA better than 20/20 and negative (-) values worse than 20/20.

    Measured: Day 30

  3. Overall Comfort Measured With Visual Analog Scale (VAS)

    The participant rated overall comfort on a 100-millimeter analog scale by marking a line that best corresponds to their eye comfort (0=very poor, 100=excellent). Both eyes were rated together as a single, retrospective evaluation of the previous 3 days of wear.

    Measured: Day 30

  4. Overall Dryness Measured With Visual Analog Scale (VAS)

    The participant rated overall dryness on a 100-millimeter analog scale by marking a line that best describes how dry their eyes feel (0=not at all dry, 100=very dry). Both eyes were rated together as a single, retrospective evaluation of the previous 3 days of wear.

    Measured: Day 30

  5. Average Exposure Speed

    Exposure speed (rate of increase in exposed lens surface % (areas not protected by tear film) after the first tear film break and before the second blink) was measured with a diffuse illumination source (Tearscope) and videotography. Higher speeds indicate worse tear film dynamics. One eye (study eye) contributed to the mean.

    Measured: Day 30

  6. Minimum Protected Area

    Minimum protected area (i.e., minimum area of the lens (%) covered by the tear film during the interblink period) was measured using a diffuse illumination source (Tearscope) and videotography. A higher value indicates a larger area of the tearfilm spread evenly over the lens (i.e., less area of tear film breakage). One eye (study eye) contributed to the mean.

    Measured: Day 30

Questions about this trial

What is this clinical trial studying?

A study testing Lotrafilcon B contact lenses, Senofilcon A contact lenses and OPTI-FREE® PUREMOIST® MPDS in people with Myopia and Astigmatism, run by Alcon Research at 1 site in United States.

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 8 inclusion and 12 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 8 Dec 2014. 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 States. 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 8 Dec 2014). 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?

Mean Ex-Vivo Total Lipid Uptake Per Lens (time frame: Day 30). 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 8 Dec 2014.
