    Abstract:
    The Argus II retinal prosthesis is the first commercially available device for restoration of vision in patients with Retinitis Pigmentosa or with similar retinal pathology who still have minimal residual native vision. The technology is able to restore vision with production of artificial visual percepts which usually are given adequate useful interpretation by the visual system in most implanted patients. The technology usually produces visual perception at the level of shape identification or better in some cases enabling in many less dependence on vision substitution devices and skills. There is no consensus among vision rehabilitation practitioners on single methods for assessments, outcome measures and training, yet there is constant progress in these areas of concern. Hence the current vision rehabilitation practice related to the implantation of the Argus II retinal prosthesis is a work in progress with many learning opportunities for all involved. All agree that implementation of this technology in clinical practice requires the combined work of a multi-disciplinary team which includes a specialized surgical team as well as a specialized rehabilitation team in order to obtain optimal results. Our own experience is presented in this paper and indicates so far that the Argus II technology is beneficial to patients and that it could be successfully managed within the Canadian heath care system.
