Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical trial, led by Dr. Enitan A. Sogbesan at the Hamilton Regional Eye Clinic, St. Joseph's Healthcare Hamilton, aims to compare the efficacy and safety of non-steroidal anti-inflammatory drug (NSAID) ketorolac alone versus a combination of ketorolac and the corticosteroid fluorometholone, and a control group receiving no postoperative treatment. The trial will evaluate these treatment strategies following Selective Laser Trabeculoplasty (SLT) in patients with open-angle glaucoma. The primary objective is to determine the most effective postoperative management strategy to reduce inflammation, improve patient comfort, and control intraocular pressure (IOP). Participants will be randomly assigned to one of the three groups, with follow-up visits scheduled at 1 hour, 1 week, 1 month, 3 months, 6 months, and 1 year post-SLT. The study's findings aim to guide clinicians in optimizing postoperative care for better patient outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Selective Laser Trabeculoplasty (SLT) is a widely used procedure introduced by Latina and Park in 1995 for the management of various forms of glaucoma, including open-angle glaucoma (OAG), pigmentary glaucoma, pseudoexfoliation glaucoma, and ocular hypertension. SLT helps prevent irreversible blindness by effectively managing these conditions. However, postoperative management strategies vary among practitioners, with some prescribing NSAIDs, a combination of NSAIDs and steroids, or no treatment at all. There is no consensus on the most effective and safest approach.

This phase 4 single-centre randomized controlled trial seeks to address this knowledge gap by comparing the postoperative effects of ketorolac alone, a combination of ketorolac and fluorometholone, and a no treatment control group on inflammation and patient comfort following SLT. The hypothesis is that treatment with ketorolac alone or in combination with fluorometholone will show superior results in reducing inflammation and improving patient comfort compared to no treatment.

The study will enroll patients undergoing SLT at the Hamilton Regional Eye Clinic. Participants will be randomized into either one of two treatment groups or one control group (no treatment) and monitored for changes in IOP, visual acuity, patient comfort, and the occurrence of any complications over a one-year period. Data collected from these assessments will be analyzed to determine the comparative efficacy and safety of the three strategies.

Inclusion criteria include adults diagnosed with open-angle glaucoma, IOP greater than 16 mmHg, and visual acuity of 20/200 or better. Exclusion criteria include recent ocular surgeries, allergies to ketorolac or fluorometholone, and pregnancy. The primary outcome measure is the change in IOP from baseline, while secondary outcomes include visual acuity, anterior chamber inflammation, and patient-reported discomfort.

The trial follows CONSORT guidelines to maintain transparency and reproducibility. Ethical approval will be obtained from the Hamilton Integrated Research Ethics Board (HiREB), ensuring compliance with ethical and legal requirements.

The results of this study will inform postoperative care decisions following SLT, potentially leading to improved patient outcomes and satisfaction. This trial also aims to contribute to a more standardized postoperative management protocol for SLT, enhancing clinical practice and patient care in glaucoma treatment.

Intervention Model

SINGLE_GROUP

This study is a Phase 4 single-centre randomized controlled trial (RCT) at the Hamilton Regional Eye Clinic, St. Joseph's Healthcare Hamilton. It aims to compare postoperative treatments following Selective Laser Trabeculoplasty (SLT) in open-angle glaucoma patients. Participants are randomly assigned to one of three groups: ketorolac alone, ketorolac with fluorometholone, or no treatment (control). The primary outcome is the change in intraocular pressure (IOP) from baseline to one year post-SLT, with secondary outcomes including visual acuity, inflammation, and patient-reported discomfort. Follow-up assessments occur at 1 hour, 1 week, 1 month, 3 months, 6 months, and 1 year. The study follows CONSORT guidelines and has ethical approval from the Hamilton Integrated Research Ethics Board (HiREB). The goal is to provide reliable data on effective postoperative management strategies, enhancing clinical practice in glaucoma treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ketorolac Alone

Participants in this arm will receive ketorolac 0.5% eye drops administered twice daily for one week following Selective Laser Trabeculoplasty (SLT). Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) that helps reduce inflammation and alleviate pain. The purpose of this intervention is to assess the efficacy and safety of ketorolac alone in managing postoperative inflammation and patient comfort compared to other treatment strategies.

Group Type EXPERIMENTAL

Ketorolac 0.5% Eye Drops

Intervention Type DRUG

Participants in this arm will receive ketorolac 0.5% eye drops, administered twice daily for one week following Selective Laser Trabeculoplasty (SLT). Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) that works by inhibiting cyclooxygenase (COX) enzymes, which play a key role in the inflammatory process. This intervention aims to reduce postoperative inflammation and pain, promoting patient comfort and potentially improving outcomes following SLT.

Ketorolac with Fluorometholone

Participants in this arm will receive a combination of ketorolac 0.5% eye drops administered twice daily and fluorometholone 0.1% eye drops administered four times daily for one week following Selective Laser Trabeculoplasty (SLT). Fluorometholone is a corticosteroid that reduces inflammation by stabilizing capillary permeability and inhibiting inflammatory cell activation. This arm aims to evaluate the combined efficacy and safety of ketorolac and fluorometholone in postoperative care.

Group Type EXPERIMENTAL

Ketorolac 0.5% and Fluorometholone 0.1% Eye Drops

Intervention Type DRUG

Participants in this arm will receive a combination of ketorolac 0.5% eye drops and fluorometholone 0.1% eye drops. Ketorolac will be administered twice daily and fluorometholone four times daily for one week following SLT. Fluorometholone is a corticosteroid that reduces inflammation by stabilizing capillary permeability and inhibiting inflammatory cell activation. The combination aims to maximize anti-inflammatory effects and enhance patient comfort, potentially leading to better postoperative outcomes compared to ketorolac alone or no treatment.

No Treatment Control

Participants in this arm will not receive any postoperative treatment following Selective Laser Trabeculoplasty (SLT). This control group is included to provide a baseline for comparison against the treatment groups receiving ketorolac alone or a combination of ketorolac and fluorometholone. The purpose is to assess the natural course of postoperative inflammation and patient comfort without intervention.
