About this study

Official title: Prospective Study Comparing the Effectiveness of Zymar and Vigamox for Preoperative Antibiotic Sterilization of the Ocular Surface After Loading Dose

The purpose of this study is to analyze the effect of Zymar and Vigamox on ocular surface bacteria. We believe that Zymar will eradicate more ocular surface bacteria than Vigamox.

Read the detailed description

Topical antibiotics are frequently used before surgical procedures with the intent of targetting and reducing the number of bacteria on the surface of the eye. These bacteria serve as potential sources for post-operative infection. One commonly used method is the administration of antibiotic drops 3 times: 1 hour prior to surgery at intervals of 5 minutes. Studies in the lab have shown that the preservative benzalkonium chloride 0.005%, part of the Zymar antibiotic drop preparation, allows the antibiotic to act more effectively than the antibiotic Vigamox, which does not include this preservative.

Comparison: The effect of Zymar antibiotic eye drops on conjunctival cultures compared to the effect of Vigamox on conjunctival cultures as measured by conjunctival cultures taken prior to treatment and then one hour after administration of eye drops 3 times, at 5 minute intervals.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Moxifloxacin ophthalmic solution 0.5% and Gatifloxacin ophthalmic solution 0.3% in people with Eye Infection and Infection, run by Ophthalmic Consultants of Boston 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 3 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: status not confirmed, as of the sponsor's last update on 4 Jul 2006. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Evidence of growth and number of colonies of bacteria on chocolate agar prior to antibiotic administration, t=0 hrs. The study lists 4 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 4 Jul 2006.
