Monocular Adaptive Optics Visual Simulator (AOVIS-I)
Monocular Adaptive Optics Visual Simulator (AOVIS-I)
The procedure is guided by the custom made software and its graphical user interface. The interface has been designed to be user-friendly, being very similar to the software usually managed by the clinicians in their daily professional practice. The complete procedure in one patient takes less than 5 minutes and is completely non-invasive. The optical measurements only involve the use of low power infrared laser and the visual testing is as simple for the patients as watching television and making responses.
