An Innovative Method for Iris Positioning in a Prosthetic Eye

Aim An apparatus named "laser pointer apparatus" is proposed for accurate iris positioning in a prosthetic eye. Background Loss of an eye leads to significant psychological stress due to functional disability and societal response to the facial disablement. Custom-made eye prosthesis is a good option to rehabilitate such defects. Inaccurately positioned iris in a prosthetic eye results in squint eye appearance leading to poor esthetics and poor psychological impact among such unfortunate patients. Technique A new apparatus called a laser pointer apparatus, which is an assembly of an occlusal plane analyzer, web camera, laser pointer, and software, has been introduced for iris positioning in a prosthetic eye. Conclusion Iris positioning is one of the key steps in fabricating an eye prosthesis. Laser pointer apparatus is a reliable method for iris positioning in a prosthetic eye. Clinical significance Positioning the iris to the ideal symmetrical position is a cardinal step in the fabrication of an ocular prosthesis. This article aims to introduce a "laser pointer apparatus" to orient iris in a prosthetic eye objectively to overcome the subjective errors.
