Sorry, I don’t know what "SFO" stands for! I got the CA part.
We are linked to the American Society of Ophthalmic and Reconstructive Surgeons (ASOPRS). Their web site is "asoprs.org". You can find extremely well qulaified doctors there. There are lots in California. If what you need is a neuro-ophthalmologist, you might ask them who refers to them. The good doctors always refer to good doctors.
