What is being measured

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

  1. Percentage Change From Baseline of Corneal Swelling 8 Hours Post Fit

    Central corneal thickness was measured at baseline and 8-hour post fit with a modified optical pachometer on a Zeiss biomicroscope, interfaced to a PC. The pachometry measurement included seven readings; the computer is programmed to remove the high and low readings and to calculate the average of the remaining five readings. Only a single central corneal thickness measurement, the average of the 5 readings, was recorded by the investigator in the eCRF. The average percent change from baseline of corneal swelling was reported and was calculated as: ((Post fit - Baseline)/ Baseline) X 100.

    Measured: 8 hours post fit

Questions about this trial

What is this clinical trial studying?

A study testing etafilcon A with Lacreon, etafilcon A with Lacreon with print and etafilcon A with print in people with Corneal Swelling, run by Johnson & Johnson Vision Care, Inc. at 1 site in Canada.

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 10 inclusion and 14 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 19 Jun 2018. 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 Canada. 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 20 Jul 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?

Percentage Change From Baseline of Corneal Swelling 8 Hours Post Fit (time frame: 8 hours post fit). 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 19 Jun 2018; AzTrials last refreshed its copy on 8 Nov 2026.
