The effects of absence of stereopsis on performance of a simulated surgical task in two-dimensional and three-dimensional viewing conditions.

Bloch E, Uddin N, Gannon L, Rantell K, Jain S - Br J Ophthalmol (2014)

Bottom Line: Stereopsis is believed to be advantageous for surgical tasks that require precise hand-eye coordination.The stereo-normal group scored higher, on average, than the stereo-absent group with both eyes open under direct vision (p<0.001).High-grade stereopsis confers an advantage when performing a fine motor task under direct vision.

BJOPHTHALMOL2013304517F2: 3D med Minimally Invasive Training System.

Mentions: The task was performed under direct vision and via a monitor, part of a laparoscopic ‘box trainer’ simulation machine (3Dmed Minimally Invasive Training System (figures 2 and 3)). Each condition was repeated with both eyes open and one eye occluded. The order of the four test conditions was randomised, with three attempts of 50 s allowed for each. Monocular conditions were established by occluding the non-dominant eye with an opaque patch, and participants wore refractive correction where necessary. Both the box trainer and the ‘pea-on-a-peg’ task are validated methods for simulated laparoscopy skills training.4
