Intraocular Surgery Training
Eyesi Surgical is a high-end virtual reality simulator for intraocular surgery training. The Eyesi platform can be equipped with interfaces for cataract and vitreoretinal surgery. Training units range from basic skills training through to surgical procedures and complications management. Validated training concepts support residencies in integrating the simulator into their program. Numerous studies have shown the effiency of training with Eyesi Surgical.
Lifelike Training Environment
Eyesi Surgical offers an immersive environment for training of surgical steps. Through the simulator´s OR microscope trainees see the virtual surgical field in stereo and high resolution while operating with lifelike surgical instruments. Just as in real surgery, discreet instrument movements are required to avoid undue wound stress, loss of viscoelastic, or diminished red reflex. The highly realistic simulation of interaction with tissue in real-time increases trainees’ surgical experience – without risk for real patients.
Cataract Training Modules
The Eyesi cataract courses include surgery training modules for capsulorhexis, hydrodissection, phaco, irrigation/aspiration, and IOL insertion as well as complications management. Abstract simulation tasks repeat and reinforce microsurgical motor skills, microscope handling, proper pivoting at the incision, and understanding of spatial boundaries.
During virtual surgery, cataract instruments such as forceps, visco cannula, cystotome, and phaco probe are available. An OR machine interface and a two-axis phaco foot pedal allow controlling fluidics. Trainees must select appropriate phaco parameters in order to safely and effectively complete a surgical procedure.
Vitreoretinal Training Modules
For training of posterior segment surgery, the Eyesi Surgical platform can be equipped with a vitreoretinal interface set. The OCULUS SDI®/BIOM® hardware mimic is operated just like a real BIOM in the operating room, and the complex interactions of auxiliary optics are accurately reproduced. Residents learn depth perception in the eye, precise usage of instruments, and correct OR machine settings.
Vitreoretinal training modules available for Eyesi Surgical include posterior hyaloid detachment, peripheral vitrectomies, internal limiting membrane peeling (ILM), the removal of epiretinal membranes, or the treatment of retinal detachments with oil or gas endotamponades.
Step-by-Step to Expert Performance
Eyesi Surgical comes with a preinstalled courseware. Starting with basic skills, the embedded courses lead trainees step-by-step to proficiency in cataract and vitreoretinal surgery. Simulator training permits residents to practice their microsurgical skills repetitively until they reach a standard skill level. Propaedeutic medical online courses, available on the VRmNet web portal, complement the practical training with Eyesi Surgical. Eyesi Surgical allows residents to gain surgical experience independent from patient flow and hospital routine.
Feedback and Evaluation
After each task, Eyesi Surgical provides trainees with a detailed evaluation of their performance, allowing them to systematically improve their skills. Required minimum scores and the repetition of tasks foster a consistent proficiency. Both educators and trainees can analyse the training data stored by the system. For networked Eyesi Surgical simulators, they can even view a comparison that ranks the individual performance against other Eyesi users.
