Evaluation of knowledge and expectations of blind and visually impaired patients regarding artificial retina

Purpose To evaluate how blind and visually impaired individuals perceive retinal prosthesis systems and to examine their views regarding potential visual outcomes. Methods A cross-sectional survey consisting of 12 structured items was distributed through the Italian Union of the Blind and Visually Impaired and regional associations. Adults with visual impairment or blindness completed questions addressing knowledge of “artificial retina” technology, information sources, expectations of visual recovery, and awareness of rehabilitation requirements. Descriptive and exploratory subgroup analyses were performed. Results Ninety-four respondents participated. Although 69% reported some familiarity with “artificial retina” technology, only 45% correctly identified its basic functional principle. Most participants obtained information from media and social networks (49%), while 17% reported receiving information from healthcare professionals. Anticipated outcomes frequently exceeded current technological capabilities: 43% anticipated restoration of pre-disease vision and 33% hoped to recognize faces. More limited outcomes, such as light perception, were considered distressing by 57% of respondents. Patterns were broadly similar across diagnostic and demographic subgroups. Conclusions Blind and visually impaired individuals show strong interest in vision restoration technologies, yet a clinically relevant gap persists between perceived potential and current capabilities. Clear, patient-centered communication and realistic counseling are essential to support informed and realistic understanding while preserving hope.
