Ocular prosthetics. Fitting, daily use and complications

Ocular prosthetics make a decisive contribution to the functional, esthetic and psychosomatic rehabilitation of patients after ocular extirpation. This article provides an overview of the fitting, daily care and complications of ocular prosthetics. The study comprised a PubMed literature review and own clinical results. Ocular prosthetics made from cryolite glass or perspex can be manufactured and fitted 5-8 weeks after removal of the eye. During this period a conformer is placed within the conjunctival sac in order to prevent scar formation and shrinking of the socket. Artificial eyes can be worn continuously, only interrupted by a short but regular cleaning procedure. Artificial tears and lid hygiene improve the comfort of wearing. Glass prostheses have to be renewed every 1-2 years, while perspex prostheses need to be polished once a year. Complications, such as giant papillary conjunctivitis or blepharoconjunctivitis sicca are facilitated by poor fit, increased age and inappropriate care of the prosthetic device. In the case of socket shrinkage or anophthalmic socket syndrome, surgical interventions are needed to re-enable the use of an artificial eye. Adequate fitting, daily care of ocular prosthetics and therapeutic management of associated complications are mandatory for a durable functional, esthetic and psychosomatic rehabilitation after ocular extirpation.
