Novel techniques for precise fixation of gaze in ocular prosthesis - Case series

Abstract

Primary goal in successful rehabilitation of a patient with ocular defect is to fabricate a well-fitted ocular prosthesis that mimics the original shape and position of the residual anatomical structures and restores volume of the defective socket. Adequate palpebral opening, iris-scleral visibility, color and size of iris, centering of pupil, shade of sclera, proper fixation of gaze and characterization of prosthesis are the key aspects that deserve meticulous attention. Fixation of gaze and selection of iris size can be achieved by various techniques. Four techniques involving usage of millimeter markings and numerical values with armamentarium such as spectacles with graphic grid, cassette holder with grid, modified graphic grid ruler, RS-3 Ophthalmic pupil distance meter coupled with digital imaging technique for iris selection are highlighted through these case series.
