Mannheim, Germany. With the upcoming software update for the Eyesi Surgical simulator, Haag-Streit Simulation is introducing an entirely new simulation model of the lens for phacoemulsification training. The simulation of the ocular tissue behavior has been optimized for the training of sculpting, cracking, chopping, emulsifying, and aspirating the lens. The Eyesi phaco divide-and-conquer and chopping training modules are now based on the same physics-based model, which adds to a highly immersive training environment.
Trainees can particularly experience the improved interaction of instruments with ocular tissue during the emulsification and chopping steps. During sculpting in the divide-and-conquer training modules, the high resolution of the lens model results in a more tight-fitting construction of the trench if instrument motion and ultrasonic energy settings are correct. Also, the behavior of lens material during aspiration is close-to-life. Collisions between lens pieces and other intraocular structures add to the realistic simulation of the restricted space in phaco surgery.
The upcoming Eyesi Surgical software release is scheduled for the end of March 2023. The new lens simulation module will require Eyesi platform versions 2.9 or later.
