Comparative Evaluation of Handheld Robot-Aided Intraocular Laser Surgery

Area of Science:

• Robotics
• Ophthalmology
• Medical Engineering

Background:

• Intraocular laser surgery requires high precision to avoid retinal damage.
• Current surgical methods may have limitations in maintaining consistent tool-tip proximity.
• Robot-assisted surgery offers potential for enhanced control and safety.

Purpose of the Study:

• To present and evaluate a novel handheld robot, Micron, for robot-aided intraocular laser surgery.
• To demonstrate the capability of visual servoing for precise laser probe manipulation.
• To assess the effectiveness of different control methods in robot-aided intraocular laser surgery.

Main Methods:

• Development of the Micron handheld robot system with an integrated micromanipulator.
• Implementation of visual servoing for real-time control of the laser probe.
• Conducting a comparative study evaluating various control strategies for surgical tasks.

Main Results:

• The Micron robot successfully enabled visual servoing of the laser probe.
• Constant tool-tip distance from the retinal surface was maintained during simulated procedures.
• Comparative analysis provided insights into the performance of different control methods.

Conclusions:

• Robot-aided intraocular laser surgery using the Micron system is feasible and offers enhanced precision.
• Visual servoing is a key enabling technology for maintaining critical distances in ophthalmic surgery.
• Further evaluation of control strategies is recommended for optimizing surgical outcomes.
