What does this research mean for the field?

In ophthalmic microsurgical training, a 3D heads-up visualization system yields comparable objective performance to conventional microscopy for vitrectomy but lower performance for cataract procedures, despite offering perceived ergonomic and didactic advantages. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To compare the training efficacy, objective performance, and subjective ergonomics between a conventional operating microscope and a 3D heads-up visualization system using a virtual reality eye simulator in microsurgical novices.

Key Points

To compare the training efficacy, objective performance, and subjective ergonomics between a conventional operating microscope and a 3D heads-up visualization system using a virtual reality eye simulator in microsurgical novices.
Prospective single-center crossover study enrolling 16 medical students with prior ophthalmology exposure and 16 ophthalmology residents without prior microsurgical experience (total N=32).
Participants completed standardized cataract and vitrectomy modules on the EyeSi simulator using both a conventional ocular microscope and a 3D heads-up display.
Assessed objective performance metrics alongside subjective questionnaire ratings concerning safety, instrument handling, comfort, movement precision, and instructor interaction.
Overall simulation scores did not differ significantly between systems (p=0.376), with vitrectomy scores remaining similar (p=0.126), whereas the conventional microscope produced significantly higher scores in the cataract module (p=0.023).
Subjective evaluation significantly favored the 3D heads-up system for surgical control (p=0.013), instrument handling (p=0.033), movement precision (p<0.001), physical comfort, and instructor interaction (p<0.001).
Medical students showed a tendency toward preferring the 3D heads-up system while residents leaned toward conventional microscopy (p=0.183), with all trainees perceiving skill transferability from 3D to conventional optics.
