Workflow with the SG3000 System

This video gives a demonstration of the workflow with the SG3000 system (SMI, Teltow, Germany). Preoperatively, a measurement is performed with the reference unit. This measurement acquires a high definition image of the eye, while at the same time keratometry is performed. The steep and flat meridians of corneal astigmatism, as well as the position of the pupil and limbus are shown in an overlay in this image.
Intraoperatively, this image is loaded into the Surgery Pilot, which is connected to the operating microscope. Next, the different steps of the surgery may be planned: the position of the surgeon, the location and size of the incision and capsulorrhexis and, in case of a toric IOL, the alignment axis is configured. The Surgery Pilot uses eye-tracking technology, based on blood vessel and iris characteristics, to match the live surgery image with the preoperative image. Using the optional microscope embedded display, the overlays for the incision, capsulorhexis, IOL centration and toric IOL alignment are visible in the operating microscope. These overlays allow the surgeon to increase the accuracy of making incisions, capsulorhexis and to centrate and align IOLs.
