What is being measured

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

  1. Percentage of Subjects With Visibly Clean Lenses

    Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. A lens was considered visibly clean if it had nondetectable films or deposits. One eye (study eye) contributed to the analysis.

    Measured: Day 7, Day 30, Day 60, Day 90

  2. Percentage of Subjects With Crystalline Deposits by Type

    Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered: Type II = films or deposits visible only under special conditions, such as special illumination using an eyepiece of 7-10 times magnification, Type III = films or deposits readily visible on a dry lens under room lighting, with unaided eye, and Type IV = films or deposits obvious under room lighting, with unaided eye, when the lens is wet or dry. One eye (study eye) contributed to the analysis.

    Measured: Day 7, Day 30, Day 60, Day 90

  3. Percentage of Subjects With Film Deposits by Type

    Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered: Type II = films or deposits visible only under special conditions, such as special illumination using an eyepiece of 7-10 times magnification, Type III = films or deposits readily visible on a dry lens under room lighting, with unaided eye, and Type IV = films or deposits obvious under room lighting, with unaided eye, when the lens is wet or dry. One eye (study eye) contributed to the analysis.

    Measured: Day 7, Day 30, Day 60, Day 90

  4. Average Residual Lens Lysozyme

    Worn study lenses were removed and analyzed by high performance liquid chromatography (HPLC) for residual lens lysozyme (protein). Values reported as lower than the limit of quantitation or none detected were imputed as 0.5 μg or 0 μg, respectively. A lower value indicates less lysozyme deposition. One eye (study eye) contributed to the analysis.

    Measured: Day 30/Early Exit

  5. Percentage of Subjects With Change From Baseline in Contact Lens-Corrected Distance Visual Acuity (CLCDVA) by Line Change

    Distance VA was assessed for each eye individually while reading a chart distant to the participant in dimmed room illumination. VA was measured using a Snellen chart, with 20/20 Snellen acuity considered normal distance-eyesight. A line increase indicates an improvement in VA. One eye (study eye) contributed to the analysis.

    Measured: Baseline (Day 0), Day 7, Day 30, Day 60, Day 90

  6. Average Lens Wear Time

    Subject recorded a response to the question, "Averaging over the last 3 days, how many hours per day did you wear your contact lenses?" Lens wear time was measured in hours.

    Measured: Day 7, Day 30, Day 60, Day 90

  7. Number of Unscheduled Lens Replacements by Reason

    A fresh pair of lenses was dispensed on Day 0, Day 30, and Day 60. Lenses replaced at other times were considered unscheduled. The counts in the table represent the total number of unscheduled lenses replaced by reason for any eye, any subject.

    Measured: Up to Day 90

  8. Likert Item - "When I Use This Solution, my Lenses Are Comfortable All Day."

    Lens comfort was assessed by the subject as a single response on a 5-point Likert scale (Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree) to best describe their lens wearing experience over the last 3 days. Responses were summarized by agreement category and presented as percentage of subjects.

    Measured: Day 7, Day 30, Day 60, Day 90

  9. Likert Item - "When I Use This Solution, at the End of the Lens Wearing Day my Vision is Clear."

    Clear vision was assessed by the subject as a single response on a 5-point Likert scale (Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree) to best describe their lens wearing experience over the last 3 days. Responses were summarized by agreement category and presented as percentage of subjects.

    Measured: Day 7, Day 30, Day 60, Day 90

  10. Likert Item - "When I Use This Solution, I Like the Way This Product Feels During Handling."

    Product handling was assessed by the subject as a single response on a 5-point Likert scale (Strongly Agree, Agree, Undecided, Disagree, Strongly Disagree) to best describe their lens wearing experience over the last 3 days. Responses were summarized by agreement category and presented as percentage of subjects.

    Measured: Day 7, Day 30, Day 60, Day 90

  11. Crystalline Deposit Area Covered

    Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. Values were reported as a percentage of lens area covered. One eye (study eye) contributed to the analysis.

    Measured: Day 7, Day 30, Day 60, Day 90

  12. Film Deposit Area Covered

    Worn study lenses were removed and evaluated for deposits. Deposits found on the lenses were defined using a 3-part classification system consisting of general visibility, the specific appearance and area covered. Values were reported as a percentage of lens area covered. One eye (study eye) contributed to the analysis.

    Measured: Day 7, Day 30, Day 60, Day 90

Questions about this trial

What is this clinical trial studying?

A study testing FID 120947A contact lens disinfecting solution, renu fresh multi-purpose solution and Soft contact lenses in people with Myopia and Astigmatism, run by Alcon Research.

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 4 inclusion and 11 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 9 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

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 9 Jun 2015). 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?

Percentage of Subjects With Visibly Clean Lenses (time frame: Day 7, Day 30, Day 60, Day 90). The study lists 12 primary outcomes in all. 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 9 Jul 2015.
