Replicating the remnant iris using an optometry trial frame: A clinical technique.

Anophthalmia, resulting from trauma, carcinoma, or congenital causes, necessitates orbital rehabilitation to address both psychological and cosmetic needs. Traditional methods for positioning ocular prostheses have frequently been inaccurate because of errors caused by parallax and differences in facial symmetry. A novel technique is described for replicating the remnant iris using an optometry trial frame to improve the precision and efficiency of custom orbital prosthesis fabrication. The described technique uses a trial framework for precise iris alignment, facilitating measurement transfer from the healthy eye to the wax pattern for the prosthesis. This technique ensures accurate, symmetrical iris positioning by aligning facial midline landmarks and simplifying the clinical workflow. It is cost-effective, less time-consuming, and accessible even for the less experienced, making it advantageous for patients who cannot afford more complex or expensive treatments like surgical or implant-retained fixed prostheses. The technique has been successful in restoring esthetics and self-confidence for individuals with exenterated or enucleated eyes, addressing gaps in traditional techniques.
