A novel device offers realistic practice for anterior segment surgery. It uses variable suction for reliable globe fixation and intraocular pressure control during surgical training.

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Biomedical Engineering

Background:

  • Current methods for practicing anterior segment surgery lack realism.
  • Cadaver globe fixation techniques are often cumbersome or inconsistent.

Purpose of the Study:

  • To develop a realistic and reliable method for practicing anterior segment surgery.
  • To create a device for consistent globe fixation and intraocular pressure control.

Main Methods:

  • A Styrofoam head was modified with a funnel and tubing system.
  • Variable external suction was applied to a globe in an artificial socket.
  • Prototypes were tested in a wet lab environment.

Main Results:

  • The device demonstrated reliable globe fixation.
