Imaging of boston keratoprosthesis type 1

Boston keratoprosthesis is an important surgical alternative for visual rehabilitation in patients with end-stage corneal or ocular surface disease. However, due to potential postoperative complications including inflammation, infection, and scarring, frequent examination and monitoring are required. Clinical examination techniques such as slit lamp biomicroscopy and gonioscopy provide limited observation of the anterior segment and angle anatomy. Recent advances in imaging techniques including ultrasound biomicroscopy and optical coherence tomography (anterior segment, optic nerve head, macula) are valuable and noninvasive tools that provide detailed visualization of ocular anatomy and augment current clinical examination methods. Thus, evaluation and monitoring of postoperative complications such as infection, corneal melt, retroprosthetic membrane formation, glaucoma, and macular edema may be improved. Furthermore, these imaging modalities may play an important role in evaluating and improving current device design and surgical technique as further details of KPro-anterior segment dynamics become better understood.
