Area of Science:

Ophthalmology
Prosthetic Devices
Biomedical Engineering

Background:

Anophthalmia and ocular defects cause significant psychological distress.
Custom-made ocular prostheses are crucial for rehabilitation.
Inaccurate iris positioning in prosthetic eyes leads to poor aesthetics and psychological impact.

Purpose of the Study:

To introduce a novel laser pointer apparatus for precise iris positioning in prosthetic eyes.
To overcome subjective errors in the fabrication of ocular prostheses.
To enhance the aesthetic and functional outcomes of prosthetic eyes.

Main Methods:

Development of a laser pointer apparatus.
The apparatus integrates an occlusal plane analyzer, webcam, laser pointer, and software.
Utilized for objective iris orientation in prosthetic eye fabrication.

Main Results:

The laser pointer apparatus provides accurate iris positioning.
Demonstrated reliability in achieving ideal symmetrical iris placement.
Offers an objective method to counteract subjective errors in prosthesis fitting.

Conclusions:

Iris positioning is a critical step in ocular prosthesis fabrication.
The laser pointer apparatus is a reliable and objective method for iris positioning.
This technique improves the quality and patient satisfaction with prosthetic eyes.
