What this trial studies

This study investigates the use of endoscopic assistance for peeling the anterior hyaloid membrane during Boston keratoprosthesis type 1 surgery. The goal is to reduce postoperative complications such as retroprosthetic membrane formation and glaucoma progression. By performing pars plana vitrectomy (PPV) concurrently with keratoprosthesis surgery, the study aims to improve visual outcomes and decrease the incidence of complications. The methodology involves a complete PPV with endoscopic assistance to enhance visualization during the peeling process.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 who are suitable for both Boston keratoprosthesis and pars plana vitrectomy.

Not a fit: Patients who are not candidates for keratoprosthesis or those requiring repeat surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce vision loss and complications for patients undergoing keratoprosthesis surgery.

How similar studies have performed: Previous studies have shown that combined surgeries can reduce complications, suggesting this approach may be beneficial.
