Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older who require corneal transplantation due to previous transplant failures and have poor visual acuity.
✕Probably not a fit
Patients with terminal glaucoma or severe retinal diseases are unlikely to benefit from this study.

What this trial studies
This study investigates the optimal timing for the implantation of a glaucoma drainage device (GDD) in patients receiving a Boston keratoprosthesis (KPro) for corneal transplantation. The KPro is used to replace a damaged cornea in patients with a history of failed corneal transplants, but it can lead to complications such as glaucoma. The study aims to determine the best approach to prevent glaucoma-related vision loss by assessing the timing of GDD placement in relation to KPro surgery. By analyzing patient outcomes, the study seeks to establish guidelines for managing glaucoma in this complex patient population.
Why it matters
Potential benefit: If successful, this study could significantly reduce the risk of glaucoma and associated vision loss in patients undergoing corneal transplantation with KPro.
How similar studies have gone: While the management of glaucoma in KPro patients is challenging, there is limited consensus on the timing of GDD placement, indicating that this approach may be novel and untested.
