“…Khakhar et al showed that head positioning and gaze control to make adjustments to a microscope during micro neurosurgery was faster than traditional manual manipulation. 28 There is scope for the use of eye tracking and augmented reality to be used in pre-operative planning and intra-operative navigation of anatomy. One study used gaze tracking in a simulation setting to plan the trajectory of insertion for probes used in deep brain stimulation.…”

BackgroundSurgery is constantly evolving with the assistance of rapidly developing novel technology. Eye‐tracking devices provide opportunities to monitor the acquisition of surgical skills, gain insight into performance, and enhance surgical practice. The aim of this review was to consolidate the available evidence for the use of eye‐tracking in the surgical disciplines.MethodsA systematic literature review was conducted in accordance with PRISMA guidelines. A search of OVID Medline, EMBASE, Cochrane library, Scopus, and Science Direct was conducted January 2000 until December 2022. Studies involving eye‐tracking in surgical training, assessment and technical innovation were included in the review. Non‐surgical procedures, animal studies, and studies not involving surgical participants were excluded from the review.ResultsThe search returned a total of 12 054 articles, 80 of which were included in the final analysis and review. Seventeen studies involved eye‐tracking in surgical training, 48 surgical assessment, and 20 were focussing on technical aspects of this technology. Twenty‐six different eye‐tracking devices were used in the included studies. Metrics such as the number of fixations, duration of fixations, dwell time, and cognitive workload were able to differentiate between novice and expert performance. Eight studies demonstrated the effectiveness of gaze‐training for improving surgical skill.ConclusionThe current literature shows a broad range of utility for a variety of eye‐tracking devices in surgery. There remains a lack of standardization for metric parameters and gaze analysis techniques. Further research is required to validate its use to establish reliability and create uniform practices.
