In recent years, the heightened success of the Boston Keratoprosthesis type I (KPro) has broadened its indications and also uncovered new complications, the most common being retroprosthetic membrane formation, endophthalmitis, progression of glaucoma and infectious keratitis.1 This study reports on the development of delayed appositional suprachoroidal haemorrhage in two aniridic patients, a rare complication post-KPro surgery.
A 69-year-old woman with aniridia and glaucoma presented 3 days post-KPro surgery OD with pain and decreased vision. Ocular history included an extracapsular cataract extraction with vitrectomy OD and a KPro surgery OS. Medical history was non-contributory. On exam, visual acuity was light perception (CF (counting fingers) preop and HM (hand motion) on postop 1 day) and the intraocular pressure (IOP) on manual palpation was 5 mm Hg OD and 15 mm Hg OS. Biomicroscopy revealed an injected conjunctiva, a formed anterior chamber, intact sutures and a well-placed KPro covered by a soft contact lens. B-scan confirmed the presence of a suprachoroidal haemorrhage. …
