Eyesi Slit Lamp provides the same degrees of freedom and controls as the Haag-Streit BQ 900 slit lamp, such as: rotation and three-axis position of illumination and observation system, slit width and length, inclination and rotation of the slit beam, and filters. As trainees look into the microscope, they see exactly what they would expect to see if there was a real patient sitting in front of them. This immersive training experience makes the transition to examining patients with a real slit lamp as easy as can be.
