Eyesi Slit Lamp is a high-end diagnostic training system for ophthalmologists and optometrists. Its virtual reality technology is integrated into the original hardware of the Haag-Streit BQ 900 slit lamp model. Trainees can examine virtual patients with the biomicroscope, fundoscopy lens, or gonioscopy lens. Eyesi Slit Lamp simulates all functions of the real slit lamp. The highly realistic simulation of the visualization of intraocular structures in real-time provides a close-to-life training experience.
