Official title
Longitudinal Observation and Assessment of the Suprachoroidal Retinal Prostheses
Overview
This is a longitudinal observational study with participants who have been implanted with the suprachoroidal retinal prosthesis.
Detailed description
To observe and assess visual, orientation and mobility behavior with primary and adjunct vision processing (AVP) methods that may enhance the performance with the suprachoroidal retinal prosthesis (ScRP). To investigate the effectiveness of primary and AVP methods in the laboratory and real-world environments with the ScRP. Assess structural and functional ScRP stability with objective and subjective assessments. Record participant experiences and feedback with the ScRP.
Primary outcome measures
- Effectiveness of vision processing method in the laboratory. [Time frame: 5 years.]
- Effectiveness of vision processing method in the 'real world' featured environment. [Time frame: 5 years.]
Secondary outcome measures (3)
- Device stability and functionality. [Time frame: 5 years.]
- Participant experience. [Time frame: 5 years]
- Participant interview. [Time frame: 5 years]
