Lotrafilcon B, then senofilcon COtherLotrafilcon B contact lenses worn first, followed by senofilcon C contact lenses, as randomized. Each product worn bilaterally (in both eyes) for a total duration of 30 (+ 3) days under a daily wear modality for the specific study period. The lenses will be removed every night and cared for with the subject's habitual lens care solution.

What is being measured

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

  1. Mean Ex-vivo Total Lipid Uptake (Total of Surface and Bulk Uptake) Per Lens

    Contact lens was removed aseptically from the eye. Total lipid (fatty deposits) uptake, defined as total amount of lipids (surface and bulk) absorbed/adsorbed and extracted, was measured in micrograms. A lower value indicates better results. Only one lens from each subject contributed to the analysis.

    Measured: Day 30 after 10 hours of wear, each product

Questions about this trial

What is this clinical trial studying?

A study testing Lotrafilcon B contact lenses and Senofilcon C contact lenses in people with Refractive Error, 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 5 inclusion and 7 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 25 Jul 2019. 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?

Yes. Results are posted in the registry (first posted 25 Jul 2019). 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 (Total of Surface and Bulk Uptake) Per Lens (time frame: Day 30 after 10 hours of wear, each product). 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 25 Jul 2019.
