This study developed a rabbit model for continuous curvilinear capsulorhexis (CCC) training. Treated rabbit lenses and eyes provide a realistic simulation for cataract surgery instruction.

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Animal Models

Background:

  • Developing effective surgical training models is crucial for resident education.
  • Current models may not fully replicate the nuances of human cataract surgery.

Purpose of the Study:

  • To develop and evaluate a rabbit model for continuous curvilinear capsulorhexis (CCC) instruction.
  • To assess the fidelity of rabbit lenses and eyes as training tools for capsulorhexis.

Main Methods:

  • Isolated rabbit lenses and eyes were treated with paraformaldehyde (PFA) fixative.
  • Cataract surgeons performed CCC on treated models and evaluated their utility.
  • A Likert scale questionnaire assessed the realism and usefulness of the models.

Main Results:

  • Rabbit lenses treated with PFA simulated human lens capsules across various age groups.
  • Fixative-treated rabbit eyes mimicked aspects of the human anterior chamber experience.
  • Some treatment conditions resulted in shallower anterior chambers and corneal clouding.

Conclusions:

  • Experienced surgeons strongly agreed that fixative-treated rabbit lenses offer a realistic CCC simulation.
  • Both rabbit lens and eye models were deemed useful for capsulorhexis training.
  • Rabbit lenses treated with 8% PFA for 15 minutes showed high fidelity for CCC training.
