Summary
22 UC Davis veterinarians using augmented-reality glasses were more accurate in simulated canine head and neck surgery tasks, with no meaningful slowdown in completion time.
Distance error fell to 2.73 mm from 3.42 mm when targets were displayed directly in the headset instead of recalled from memory; area-tracing accuracy rose to about 84% from 63%.
The proof-of-concept test used a holographic 3D dog head with an oral tumor to mimic tasks such as locating coordinates and tracing tumor margins, addressing the depth limits of standard 2D imaging on separate monitors.
Usability averaged 3.55 out of 5, and researchers noted hand-tracking lag after more than 90 minutes; more-experienced veterinarians made fewer errors, while specialty did not significantly affect performance.
Because the study was small, single-center and conducted on simulation rather than live tissue, the next step is clinical validation in actual veterinary surgeries.
