Nice. But, clinical trials are next step?? ... I have so many questions!!

What will the sensation of light look like to a patient?

What steps can be taken to undo progress if the sensation is undesirable (or worse, painful or triggering of pain) and a patient wishes to withdraw from the study?

Will differentiated cells implanted in suspension and locate its target, or as tissue, carefully laid on its respective layer?

What optic training (stimuli) are necessary for integration of the new sensory information? What stimuli will be counterindicated?

The future is awesome, but I would accommodate those first volunteers with a lot of money and accessible wellness support. 😶
