Area of Science:

  • Ophthalmology
  • Prosthodontics
  • Medical Device Design

Background:

  • Anophthalmia requires orbital rehabilitation for psychological and cosmetic needs.
  • Traditional ocular prosthesis methods suffer from parallax and facial asymmetry errors.
  • Existing treatments can be costly and inaccessible for some patients.

Purpose of the Study:

  • To introduce a novel, cost-effective technique for precise ocular prosthesis fabrication.
  • To improve the accuracy and efficiency of custom orbital prosthesis positioning.
  • To enhance patient self-confidence and esthetics through improved prosthesis fit.

Main Methods:

  • Utilizing an optometry trial frame for accurate remnant iris replication.
  • Employing facial midline landmarks for precise iris alignment.
  • Transferring measurements from the healthy eye to the prosthesis wax pattern.

Main Results:

  • Achieved accurate and symmetrical iris positioning in custom orbital prostheses.
  • Demonstrated a simplified and efficient clinical workflow for prosthesis fabrication.
  • Successfully restored esthetics and self-confidence in patients with anophthalmia.

Conclusions:

  • The novel technique offers a precise, accessible, and cost-effective solution for orbital prosthesis fabrication.
  • This method addresses limitations of traditional techniques, particularly for patients with limited resources.
  • Improved ocular prosthesis fabrication enhances patient quality of life and psychological well-being.
