Find An Opthamologist

How do i find an opthamologist near berkeley, ca?

How can I find an Opthamologist that has a sliding scale?
My girlfriend has had vision problems all of her life. She has had multiple lasik surgeries. We recently went to a vision doctor that cost about 200 per visit, just to find out what is wrong with her eyes. She constantly has migraines that originate at the eyes and lasts for days. Also, she is 80 % blind in one of her eyes. So we go to this doctor and he's a real jerk. Like if you dont have money just leave kinda guy. Anyways he looks at the pictures of her eyes that the assistant took and says she has scar tissue in the eye that is 80 % blind and has glaucoma in the other eye. Then he says that she needs treatment for it like Xrays and other things to further test for it. Then, he says its going to cost thousands of dollars and just leaves the room. The assistant escorts us out and we pay and leave without seeing him again. We were just shocked and really upset. He just spit all of that bad news at us in no time and left without a care in the world. Apparently in my city the health department has no vision services and i cant seem to find any opthamologists with a sliding scale so that we can afford to have her treated. Meanwhile, she continues to hurt and we feel helpless. If anyone can help it would be appreciated. How can we find an opthamologist with a sliding scale?
