Hi. I'm online and happy to answer your question today.
That is an excellent question and it really won't make a difference what position you sit/stand/walk in at this point. For your type of procedure, positioning is not important.
I am sure that the cryo treatment worked just fine but, yes, if needed it can be refrozen, treated with a laser or if necessary surgery can be done.
I'm actually surprised that your doctor did not give you a handout about your cryo treatment....my nurse gives out one to all my patients. Oh well, no big deal.....you've got me :-)
You don't need to worry about the cryo not working as it is very effective. You will not wake up with no vision in that eye. Just try to relax and anytime you have a question or concern just let me know and I'll be happy to help.
