This study introduces a novel teaching method for cataract surgery using microendoscopic visualization during phacoemulsification. This technique improved surgical guidance and revealed details missed by standard microscopes, enhancing surgical education and outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Medical Technology

Background:

  • Traditional cataract surgery teaching relies on lectures, wet labs, and direct surgical participation.
  • Limitations exist in current teaching methods for complex surgical maneuvers and intraoperative visualization.

Purpose of the Study:

  • To describe a new method for teaching cataract surgery using microendoscopic visualization.
  • To evaluate the utility of intraoperative endoscopic visualization during phacoemulsification and intraocular lens (IOL) implantation.

Main Methods:

  • A microendoscopic cyclophotocoagulation device was utilized during phacoemulsification cataract extraction and posterior chamber IOL implantation.
  • Endoscopic visualization was employed in 4 eyes of 4 patients undergoing the procedure.

Main Results:

  • Endoscopic visualization facilitated corneal incision construction, capsulorhexis edge localization, and lens groove depth estimation.
  • The endoscope identified subtle clinical findings, including misplaced IOL haptics and residual lens cortex, not visible with the surgical microscope.

Conclusions:

  • Microendoscopic visualization during cataract surgery offers enhanced intraoperative guidance.
  • This technique improves the educational value of surgical training and contributes to better surgical outcomes.
