A Study for Manufacturing Light Artificial Eye

ABSTRACT

PURPOSE: To manufacture a light artificial eye that is lighter in weight than a conventional artificial eye and to correct the problems resulting from the long-term use of artificial eyes in anophthalmic patients. METHODS: The light artificial eyes were manufactured by substituting their posterior portions with a lightweight material, polystyrene. The conventional artificial eyes manufactured with polymethylmethacrylate (PMMA) and sold by the American Optical Corporation were used as the control. The control was grouped according to 3, 4, and 5 grams in weight with 8 sets in each group. The light artificial eyes that have the same volume and shape as the conventional ones was compared in terms of the reduction rates of weight with each group. RESULTS: The reduction rates of weight in the light artificial eyes were 22.6%, 40.2%, and 46.7% in the 3-, 4-, and 5-gram groups, respectively. In addition, the light artificial eyes showed significant statistical differences from the conventional ones. CONCLUSIONS: The light artificial eye, the posterior portion of which was substituted with a lightweight material, showed a significant reduction in weight, and the rate of weight reduction was higher with the heavier groups. Therefore, the lightweight artificial eye, which has fewer side effects to the orbit and adnexa, could contribute to the rehabilitation of the anophthalmic patients.
