The heads-up digital stereoscopic display has recently been introduced in vitreoretinal surgery. This system is proposed to facilitate surgical teaching by providing a panoramic view with enhanced depth-of-field and by allowing the operating team to see the surgeon’s view in real-time. We conducted a retrospective review of surgical cases performed during the transition to the digital stereoscopic display in our vitreoretinal fellowship program to study surgical times, complications and reoperation rates.
Two hundred and fifty-one consecutive cases performed 7 months before and 7 months after the transition to the stereoscopic display by the same surgeons were reviewed retrospectively. Surgeries were grouped into primarily vitreous cases (n=52), primarily macular cases (n=99), and complex cases (e.g. tractional retinal detachments, proliferative vitreoretinopathy) (n=100). Surgical times, complications, and reoperation rates were noted. Two-tailed Student’s T-test was used for statistical analysis.
There were no significant differences in reoperation rates (primarily vitreous cases: 0.8% control versus 0% stereoscopic display, P=0.16; primarily macular cases: 3.8% control versus 0% stereoscopic display, P=0.16, complex cases: 21% control versus 25.6% stereoscopic display, P=0.63). In complex cases the redetachment rate was equivalent between the stereoscopic display and the control groups (17.95% stereoscopic display versus 18% control, P=0.99). There were no differences in complications rates between the two groups (P=0.37). The surgical set-up time (wheels-in to start of surgery time) was significantly longer in the stereoscopic display group (Δ= 3 min, P< 0.001). The average surgical time was greater when the stereoscopic display was used in primarily vitreous cases (Δ= 9 min, P= 0.004), and in primarily macular cases (Δ= 5 min, P= 0.004). The average surgical time for complex cases was not significantly different between the stereoscopic display and the control groups (P= 0.61).
The transition to a heads-up digital stereoscopic display during vitreoretinal fellowship training led to an increase in surgical times and a longer surgical set-up time without increasing the complication or reoperation rates.
