First experience with The IRIS retinal implant system

Purpose To report on the first 4 months experience of a patient with the active IRIS- Implant. Methods 4 weeks after implantation the training with the active implant started. Thresholds were measured at each training day. Light perception, light localisation, point to point discrimination and motion detection were measured with special test procedures. Visual function training was performed. Results Visual perception was achieved, when the stimuli were generated by the computer and with the camera mode. All tests were successful. Conclusion Successful stimulation and major improvements during the training demonstrates that with the Iris Implant System a visual perception can be achieved, which is relevant for daily life.
