Hi, Wanda! I do not have COPD (I am one of the trained staff members here), but I did have cataract surgery a year ago. It may give you some peace of mind to know that the procedure is very quick -- I was in the operating room for about 10 minutes -- and was provided with oxygen throughout. There should be an anesthesiologist with you to monitor your breathing and vital signs, and they will be able to provide any support you need. Don't be afraid to talk openly with the anesthesiologist and your surgeon to make sure everyone is on the same page.
My hope for you is that you find that it was easier than you hoped. 😀 And of course, that you enjoy better vision once you recover! Please keep us posted, okay? All the best! -Melissa, copd team
