“…The application of a three-dimensional imaging system (3D) to retinal surgery is the latest and more exciting advance in the field. Previous studies demonstrated the technical feasibility of 3D surgery [ 1 , 2 ]. This new imaging system offers many advantages including a more physiological “heads-up” position for the surgeon, a very high image definition even at wider magnifications, ad hoc digital filters (e.g., to enhance vitreous visibility), lower endoillumination levels [ 3 ], and the same view between the audience (e.g., nurses, fellows, students) and the surgeon [ 1 , 2 ].…”

Here we present procedural and safety results from our initial experience using 3D heads-up vitrectomy for retinal detachment surgery. The comparison with our outcomes from previous standard surgery shows how the new 3D system seems safe and effective.Electronic supplementary materialThe online version of this article (doi:10.1186/s40942-017-0099-2) contains supplementary material, which is available to authorized users.

“…The “heads-up” three-dimensional (3D) viewing system [ Fig. 1 ] for retinal surgeries offers many technical advantages[ 1 2 ] to surgeons which include performing surgeries in a more physiologically comfortable position. It allows high-definition visualization of the retinal periphery with better magnification, presence of filters to enhance visualization of different anatomical structures, and lower illumination levels.…”

Purpose:To compare clinical outcomes of patients undergoing macular hole surgery with heads-up three-dimensional (3D) viewing system and conventional microscope.Methods:In all, 50 eyes of 50 patients with stage 3 or 4 macular hole were randomized and macular hole surgery [inverted internal limiting membrane (ILM) flap technique] was performed in 25 eyes using 3D viewing system and 25 eyes using conventional microscope. All surgeries were performed by a single surgeon. Patients were followed up for a period of 3 months. Logarithm of the minimum angle of resolution (logMAR) visual acuity, macular hole index, intraoperative parameters such as total surgical time, total ILM peel time, number of flap initiations, duration of Brilliant Blue G dye exposure, illumination intensity, postoperative logMAR visual acuity, and macular hole closure rates were recorded and compared between the two groups.Results:The mean age was 67.92 ± 7.95 and 67.96 ± 4.78 years in both groups, respectively (P = 0.98). Gender (P = 0.38) and right versus left eye (P = 0.39) were also comparable. Preoperative and postoperative best-corrected visual acuity (P = 0.86, 0.92), macular hole index (P = 0.96), total surgical time (P = 0.56), total ILM peel time (P = 0.49), number of flap initiations (P = 0.11), and macular hole closure rates (P = 0.61) were not statistically significant when compared between the two groups. Illumination intensity of microscope (100% vs 45%) and endoillumination (40% vs 13%) were significantly less in the 3D viewing system.Conclusion:The clinical outcomes of macular hole surgery using 3D viewing system are not inferior to that of conventional microscopes, and it has the added advantages of better ergonomics, reduced phototoxicity, peripheral visualization, magnification, and less asthenopia, and it serves as a good educational tool.

Background An optimal osteotomy angle avoids shortening of the first metatarsal bone after hallux valgus surgery and therefore reduces the risk of transfer-metatarsalgia. The purpose of the present ex-vivo study was to investigate whether augmented reality (AR) would improve accuracy of the distal osteotomy during hallux valgus surgery. Methods Distal osteotomies of the first metatarsals were performed on a foot model by two surgeons with different levels of surgical experience each with (AR, n=15x2) or without (controls, n=15x2) overlay of a hologram depicting an angle of osteotomy perpendicular to the second metatarsal. Subsequently, the deviation of the osteotomy angle in the transverse plane was analyzed. Results Overall, the AR decreased the range of impression and the AR guided osteotomies were more accurate (4.9 ± 4.2°) compared to the freehand cuts (6.7± 6.1°) by tendency (p=0.2). However, while the inexperienced surgeon performed more accurate osteotomies with AR with a mean angle of 6.4± 3.5° compared to freehand 10.5 ± 5.5° (p=0.02), no significant difference was noticed for the experienced surgeon with an osteotomy angle of around 3° in both cases. Conclusion This pilot-study suggests that AR guided osteotomies can potentially improve accuracy during hallux valgus correction, particularly for less experienced surgeons.
