About this study

Official title: Single-Center Clinical Evaluation of Daily Disposable Contact Lenses

The objective of the study is to compare the overall subjective preference of filcon II 3 daily disposable silicone hyrogel contact lenses compared to etafilcon A and nelfilcon A daily disposable conventional hydrogel contact lenses.

Read the detailed description

Double-masked, randomised, controlled crossover trial. Subjects were randomized to wear one or the other of the conventional hydriogel lenses; all subjects wore the filcon II 3 lenses. The first randomly assigned lens type was worn for 3 days, with daily replacement, followed by 3 days of wear of the other lens type, with daily replacement.

Conditions
Myopia
Being tested
filcon II 3, etafilcon A, nelfilcon A

Questions about this trial

What is this clinical trial studying?

A study testing filcon II 3, etafilcon A and nelfilcon A in people with Myopia, run by CooperVision, Inc. 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 12 inclusion and 15 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 31 Jul 2020. 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 15 Feb 2016). 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?

Overall Lens Preference - All Study Lenses (time frame: Study Exit). The study lists 2 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 31 Jul 2020.
