Augmented reality filters for iris positioning in orbital prosthesis: A clinical report

Mid-facial defects involving the eye can result in severe emotional and psychological trauma for the affected individual, apart from the loss of vision. Prosthetic rehabilitation with an orbital prosthesis can camouflage such defects when surgical treatments are limited. The fabrication of an orbital prosthesis requires precise positioning of the iris for an optimal esthetic outcome. Different techniques for accurate iris positioning in orbital or ocular prostheses have been described, but they have been subjective or require elaborate equipment. This clinical report describes a novel and digital solution for iris positioning with the help of augmented reality filters using a smartphone and Instagram app.
