VAO Voptica Video
The world´s first compact Visual Adaptive Optics simulator
VAO is a unique diagnostics device offering a complete solution. A new patented technology that incorporates the most cutting-edge Adaptive Optics (AO) based on liquid crystal. It provides an objective characterization of the eye and a real vision experience that allows the patient to test different optical solutions before surgery.
Full control over the test and the optics.
