Primary Outcome Measures :
  1. Incidence of Adverse Events related to the treatment [ Time Frame: 1 year ]
    Safety is defined as the absence of ATIMP-related safety events


Secondary Outcome Measures :
  1. Improvement in visual function [ Time Frame: 6 months ]
    Improvements in visual function as assessed by visual assessment

  2. Improvement in retinal function [ Time Frame: 6 months ]
    Improvements in retinal function as assessed by visual assessment

  3. Improvement in Quality of Life [ Time Frame: 6 months ]
    Quality of life will be measured by QoL questionnaire
