In extremely severe and rare cases, the use of technologies to restore vision, such as the Boston Keratoprosthesis (artificial cornea) or the Osteo-Odonto-Keratoprosthesis (tooth-in-eye), may be necessary. Dr Trinh sees these patients at the dedicated K-Pro Clinic based monthly at the Sydney Eye Hospital with a multidisciplinary team of retina, glaucoma and plastic surgery specialists and referrals for such patients are invited via Mosman Eye Centre.
