Opthamologist Do

How soon after the opthamologist do I get my glasses?
I have an appointment on the 27th of December with an ophthalmologist. Do I go directly to the optometrist from there, or what? And how do I get an appointment with him? How soon please my eyes are killing me.Thanks San R Claus

What is the process of laser photocoagulaton that a opthamologist does for retinal tears?
I went to my optamologist to checkup on floaters in my field of vision. He found that I have a retinal tear in my left eye. He told me that he would need to see me on Friday to seal the tear with a laser. I've never had any surgery like this done. Has anyone gone through this? What is the process like and what does it entail? How do you keep your eyes open and without blinking? Is there any pain experienced?

If currently an optometrist, is it difficult to become an opthamologist; do you have to "start over"?
Thanks Adam. I'm currently thinking about doing what you do someday. Any regrets?
