This study introduces a new method for transscleral cyclophotocoagulation, using real-time monitoring of laser transmission through eye tissues. This enhances treatment precision and safety by allowing controlled laser exposure, preventing over- or under-dosage.

Area of Science:

  • Ophthalmology
  • Medical Devices
  • Laser Surgery

Background:

  • Transscleral cyclophotocoagulation lacks direct visualization of laser effects.
  • This can lead to imprecise dosing, causing complications like pop effects or insufficient therapeutic outcomes.

Purpose of the Study:

  • To develop and evaluate a novel method for real-time monitoring and control of transscleral cyclophotocoagulation.
  • To improve the safety and efficacy of laser treatment for refractory glaucoma.

Main Methods:

  • Monitoring laser radiation reflected from the eye's fundus after passing through sclera and ciliary body.
  • Utilizing a computer system to stop laser exposure based on real-time transmission curve analysis.
  • Displaying transmission curves for surgeon-guided interruption.

Main Results:

  • The 810-nm diode laser demonstrated superior performance over the 1064-nm Nd:YAG laser due to stable output and higher tissue absorption.
  • Typical transmission curves were observed across porcine, human cadaver, and patient eyes.
  • The method enabled timely exposure interruption, preventing adverse pop effects.

Conclusions:

  • The developed monitoring system significantly enhances the precision and safety of transscleral cyclophotocoagulation.
  • Real-time feedback allows for more accurate laser energy delivery in glaucoma treatment.
