Summary
This study presents a novel eye model using a keratoprosthesis for practicing complex anterior and posterior segment surgeries. The model offers realistic tactile feedback for surgical training.
Area of Science:
- Ophthalmology
- Surgical Simulation
- Medical Education
Background:
- Surgical training requires realistic models for mastering complex procedures.
- Current models may not fully replicate the tactile feedback of live ocular tissues.
Purpose of the Study:
- To develop and evaluate a simple, effective eye model for practicing anterior and posterior segment surgeries.
- To assess the model's utility as a teaching platform.
Main Methods:
- Utilized human cadaver eyes with a Lander wide-field keratoprosthesis as an artificial cornea.
- Performed standard surgical procedures including continuous curvilinear capsulorrhexis, phacoemulsification, intraocular lens insertion, pars plana vitrectomy, and laser panretinal photocoagulation.
Main Results:
- The keratoprosthesis successfully maintained anterior chamber integrity, providing a tight seal.
- All simulated surgical steps, from cataract extraction to retinal laser treatment, were successfully executed.
Conclusions:
- The developed eye model closely mimics the tactile feel of a living eye.
- This model serves as a valuable and realistic platform for surgical practice and education in various ophthalmic procedures.
