Purpose: To evaluate the initial experience of four experienced vitreoretinal surgeons, in France, with a three-dimensional (3-D) system, and to explore the potential advantages and disadvantages of this technology. We also report anatomical surgical outcomes of full-thickness idiopathic macular holes (MH) and primary rhegmatogenous retinal detachment (RRD), by using traditional microscopy and heads-up method. Methods: Four French retinal surgeons performed several types of ophthalmic surgeries with this new technology. To compare the 3-D system with ocular viewing, ergonomics, educational value, image sharpness, depth perception, field of view, technical feasibility, advantages and disadvantages, and expectations for the future, were assessed using a questionnaire. We also compared the same questionnaire with the answers of six Brazilian experienced vitreoretinal surgeons. For treating MHs, the surgeons performed 88 surgeries (44 with microscopy and 44 with 3-D). They performed 100 PPV for treating primary RRD (50 with ocular viewing and 50 with 3-D). The visualization method for each patient, as well as the assignment of each surgeon for a specific patient, were all randomly selected. Results: On the questionnaire, 3-D was preferred to traditional microscopy, except for technical feasibility; the type of surgery benefitting most from the 3-D was macula surgery and the least was anterior segment surgery; the most used by all is the black and white filter in patients with atrophic RPE during ILM peeling. Eighty-one (92.1%) MHs was successfully closed with one surgery and out of the 100 eyes with a primary RRD, the anatomical success after 3 months of follow-up was 91%, with no statistical significance between 3-D and ocular viewing. Conclusions: The surgeons in this study preferred 3-D to ocular viewing. Vitrectomy surgery to treat MHs and RRDs can be performed using the 3-D with the same efficiency as microscopy. Digital integration of 3-D and iOCT can be useful in some cases. With continuous refinement to improve the ability to visualize inside of the eye, this promising technology may enhance what we do as surgeons.
