Virtual phacoemulsification surgical simulation using visual guidance and performance parameters as a feasible...

Area of Science:

• Ophthalmology
• Medical Simulation
• Surgical Training

Background:

• Computer-based surgical training offers a controlled environment for standardized procedures on virtual human anatomy.
• Virtual reality (VR) platforms with 3D visualization enable realistic surgical simulations.

Purpose of the Study:

• To evaluate a VR platform's effectiveness in assessing surgical proficiency.
• To compare performance in virtual phacoemulsification cataract surgery between experienced surgeons and residents.

Main Methods:

• Ten experienced ophthalmologists and six residents performed virtual phacoemulsification cataract surgery (corneal incision, capsulorhexis, phacoemulsification, IOL implantation).
• Participants completed three trials on a VR simulator with visual guidance and performance parameters.
• Performance was evaluated using a set of implemented parameters within the simulator.

Main Results:

• Experienced surgeons achieved significantly higher scores across all four main surgical procedures.
• Surgical experience correlated positively with improved completion times and reduced tremor.
• Positive correlations were also observed between experience and anti-rupture parameters.

Conclusions:

• Augmented VR simulators are feasible tools for assessing proficiency in phacoemulsification cataract surgery.
• The study indicates construct validity for VR modules with visual guidance and performance metrics.
• VR simulation provides a reliable method for evaluating surgical skills in ophthalmology.
