About this study

Official title: A Randomized, Masked Comparison of Topical Ketorolac 0,4% Versus Placebo in Cataract Surgery.

The purpose of this study is to compare effects of preoperative and postoperative use of topical ketorolac tromethamine 0.4% versus placebo in uncomplicated cataract surgery.

Patients scheduled to undergo phacoemulsification will be randomized to receive either topical prednisolone acetate 1% 4 times daily (QID) plus dextran 70/hypromellose QID (placebo group) or topical prednisolone 1% QID plus ketorolac tromethamine 0.4% QID (ketorolac group) for three days preoperatively and four weeks postoperatively. The primary outcome 5 weeks after surgery will be angiographic cystoid macular edema.

Purpose:

To compare effects of preoperative and postoperative use of topical ketorolac tromethamine 0.4% versus placebo in uncomplicated cataract surgery.

Methods:

This will be a masked single-center, randomized clinical study comprising 80 patients undergoing phacoemulsification cataract surgery. Patients scheduled to undergo phacoemulsification and with no recognized cystoid macular edema (CME) risks (diabetic retinopathy, retinal vascular disease or macular abnormality) will be randomized to receive either topical prednisolone acetate 1% 4 times daily (QID) plus dextran 70/hypromellose QID (placebo group;n=40) or topical prednisolone 1% QID plus ketorolac tromethamine 0.4% QID (ketorolac group;n=40) for three days preoperatively and four weeks postoperatively. In both groups topical gatifloxacin will be administered to the treated eye QID, starting three days before surgery and continuing for seven days. The primary outcome 5 weeks after surgery will be angiographic cystoid macular edema. Other included outcomes will be best corrected visual acuity (BCVA), intraocular pressure (IOP), CME incidence, retinal thickness as measured by spectral-domain optical coherence tomography (OCT).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ketorolac Tromethamine in people with Cystoid Macular Edema Following Cataract Surgery, Bilateral, run by University of Campinas, Brazil at 2 sites in Brazil.

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 1 inclusion and 9 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 4 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Brazil. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

cystoid macular edema (time frame: 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01542190, which also lists 8 linked publications.

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 Dec 2014.
