That would be an individual's decision. Those families that I know where their parents and/or love ones are suffering from Dry AMD or SMD, are always under their Doctor's care. Their Insurance cover certain aspects, the remainder is out of pocket. That is how these Clinical trial patients were selected. One's vision acuity is the most precious health issue when declared "legally blind". The costs to being declared "legally blind" is like staggering in home care help, family members helping etc. etc.
The alternative to receiving RPE and visual acuity improvement is like a no-brainer.
