A simplified approach for placing the iris disc on a custom made ocular prosthesis: report of four cases.

This case report describes a series of four cases of different age group, in which a simplified approach was applied for positioning the iris disc on a custom made ocular prosthesis. For each of the patient, a pre-fabricated eye was selected; whose iris and pupil closely matched that of the natural eye. This was duplicated for use as a tray in impression procedure. Iris portion of the stock eye was trimmed out and oriented on the cast according to previously transferred pupillary mark. This stock eye-wax pattern combination was tested in the eye socket, modified accordingly and finally cured in transparent heat cured acrylic resin. The technique to fabricate ocular prosthesis in present case reports modifies pre-fabricated eye prosthesis to a custom-made fit and aesthetics. This helped us to overcome the disadvantages of poor fit, inadequate movement and complex painting procedure and technique involved in making a custom-made ocular prosthesis. It can be concluded that close adaptation of the custom-made ocular prosthesis to the tissue bed provides maximum comfort and restores full physiologic function to the accessory organs of the eye.
