Eyesi Surgical

Eyesi Surgical simulator for cataract surgery

Cataract and Vitreoretinal Surgery Training

Eyesi® Surgical is a high-end virtual reality simulator for intraocular surgery training. You can equip the Eyesi platform with interfaces for cataract and vitreoretinal surgery. Trainees see the virtual surgical field in stereo and high resolution while operating with handpieces that imitate surgical instruments.

Practice Without Risk for Patients

The highly realistic simulation of cataract and vitreoretinal procedures increases the trainees’ microsurgical skills without risk for patients. Numerous studies prove that inexperienced surgeons who trained on Eyesi Surgical have lower complication rates during intraocular surgery than peers who did not.

Cataract Surgery Training

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. Just as in real surgery, discreet instrument movements are required to avoid undue wound stress, loss of viscoelastic, or diminished red reflex. 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 Surgery Training

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. A realistic posterior segment surgical simulation environment is provided through the use of scleral indentation, a vitrectomy machine, variable illumination intensity of the light pipe, and an endolaser.

Pre-Installed Simulator Curriculum

The training curriculum Eyesi Courseware permits the repetitive practice of microsurgical skills, something that is not accomplishable in the wet lab. Starting with basic skills, the courseware leads trainees step-by-step to proficiency in cataract and vitreoretinal surgery. Optional online courses on VRmNet supplement the simulator training.

Assessment and Performance Comparison

Performance comparison on Eyesi Surgical

Eyesi Surgical provides trainees with performance feedback on surgical efficiency after each task, so that they can systematically improve their skills. Minimum scores and repetition of tasks foster proficiency and consistency. Further, trainees can view a comparison that ranks the individual performance against other users.

Numerous studies have proven the effectiveness of practicing with Eyesi Surgical and have shown that both beginners and experienced surgeons can benefit from simulator-based training regarding surgical skills and complication rates in the OR. Visit the studies page for examples.
