Using laser treatment to manage glaucoma in patients receiving a Boston keratoprosthesis

The Role of Transscleral Cyclophotocoagulation in Patients Undergoing a Boston Keratoprosthesis

Not applicable Interventional Centre hospitalier de l'Université de Montréal (CHUM) · NCT04232982

This study is testing a laser treatment to see if it can help manage glaucoma in patients who have received an artificial cornea to improve their vision.

What this trial studies

This clinical trial investigates the effectiveness of transscleral cyclophotocoagulation (TS-CPC) in patients undergoing a Boston keratoprosthesis, an artificial cornea used for vision restoration. The study aims to address the high prevalence of glaucoma in these patients, which can lead to significant vision loss post-surgery. By employing advanced laser techniques, the trial seeks to reduce intra-ocular pressure and improve glaucoma management in this specific patient population. Participants will be monitored for their response to the laser treatment and its impact on their overall eye health.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients who are scheduled to receive a Boston keratoprosthesis and can provide informed consent.

Not a fit: Patients who have had prior glaucoma surgeries or those with severe ocular surface disease or terminal glaucoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve glaucoma management and preserve vision in patients receiving a Boston keratoprosthesis.

How similar studies have performed: While the use of TS-CPC has been explored in other contexts, this specific application in conjunction with the Boston keratoprosthesis is relatively novel.
