Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Area of Science:

Ophthalmology
Surgical Education
Biomedical Engineering

Background:

Surgical skills training requires realistic simulation models.
Current methods may lack adequate tactile feedback and globe manipulation capabilities.

Purpose of the Study:

To develop and evaluate a novel globe-fixation system for animal eye surgical training.
To enhance the versatility and realism of ophthalmic surgical simulators.

Main Methods:

Designed a globe-fixation system with an adjustable aperture cup utilizing vacuum for globe capture.
Incorporated a hollow base with spurs for cup movement and a ballast for tactile feedback and primary position return tendency.
System allows for adjustable globe pressure, stability, rotation, and modifiable orbit size.

Main Results:

The system provides stability, rotation, and a tendency to return to the primary position.
Adjustable globe pressure and modifiable orbit size enhance training versatility.
The design facilitates practice of various anterior segment surgical procedures.

Conclusions:

The developed globe-fixation system offers significant advantages for ophthalmic surgical skills training.
It provides a versatile platform for simulating anterior segment procedures with enhanced realism.
This system can improve trainee proficiency in animal eye surgery.
