Clinical Trial Summary

This is a longitudinal observational study with participants who have been implanted with the suprachoroidal retinal prosthesis.

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.
