20 Years of Advances in Keratoprosthesis

AbstractPurpose of ReviewKeratoprosthesis (KPro) has revolutionized the treatment of patients with severe corneal diseases who do not benefit from allogeneic corneal transplantation. Since the introduction of KPro over 200 years ago, numerous designs and techniques have been suggested. Of these, the Boston keratoprosthesis and osteo-odonto keratoprosthesis (OOKP) are the two most commonly used keratoprostheses worldwide.Recent FindingsOver the past few decades, various improvements in designs, surgical techniques, and postoperative care have expanded the indications for the Boston KPro. With better control of devastating ocular complications, such as endophthalmitis and extrusion, glaucoma has become the most common long-term complication leading to blindness. OOKP involves a more complex surgical procedure compared to the Boston KPro, but has gained traction due to its effectiveness in treating very severe ocular surface diseases.SummaryThe current trend of Boston KPro studies focuses on better intraocular assessment tools to diagnose and manage glaucoma, as well as alternative biomaterials to improve biocompatibility and retention rates. Recent improvements in OOKP mainly focus on augmentation techniques of the biological skirt to prevent or decrease both keratolysis and laminar resorption.
