Abstract

Ocular prosthesis has been a popular rehabilitation modality ever since their introduction in 1960s for patients with congenital or acquired ocular defect and patients with conditions like phthisis bulbi or sunken non-functional eye. Various advancements in materials, techniques and technology to fabricate a customized prosthesis including use of implants, Magnetic dilating pupil and others aims to satisfy patient’s expectations and improve quality of life. Function however, still remains a challenge when using conventional or modified ocular prosthesis. Concepts of treatment used for ophthalmic patients with poor or complete absence of vision includes retinal prosthesis such as bionic eye, durette implants are promising alternatives for restoring partial vision in cases with interrupted visual pathway. Concepts of biomedical engineering such as optogenetics, photovoltaic stimulation, gene based therapies holds potential for revolutionizing the treatment modalities to restore form, esthetics and function for such patients.
