Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Medical Simulation

Background:

  • Anterior capsulorhexis is a critical step in cataract surgery.
  • Traditional techniques can lead to complications like corneal distortion and anterior chamber collapse.

Purpose of the Study:

  • To present a capsulorhexis technique utilizing shearing forces with a cystotome.
  • To evaluate the technique's efficacy on a virtual reality simulator and a human eye.

Main Methods:

  • Initiating capsular tear with a cystotome to create a flap, left unfolded.
  • Engaging the flap horizontally with the cystotome near the tear's leading edge.
  • Employing circular cystotome movements to direct shearing forces and maintain flap visualization.

Main Results:

  • Reduced corneal wound distortion and anterior chamber collapse.
  • Improved visualization of the tear's leading edge.
  • Enhanced control over capsulorhexis size and tear direction.

Conclusions:

  • The EYESI Surgical Simulator provides a realistic platform for practicing this technique.
  • The shearing forces technique is a viable and often superior alternative for achieving desired capsulorhexis outcomes.
