I hope your cataract surgery goes well but that was a walk in the park compared to Retina surgery. I had debris left behind the lense on my first cataract surgery and had to have a Vetrectomy. They basically suck the gel out of your eye ball to get behind the lense to clean it out and replace it with saline solution no fun let me tell you.
Thank God my Retina did not tear then they have to put a gas bubble in and that is more a nightmare. Yes nowadays most guys want to be YouTube hero's so everyone can tell them how great they are. I think YouTube was the worse thing to happen to the hobby attracts wrong kind of people who never had interest in history just greed and destroying property till it's no fun anymore. That's my grumpy old man rant for the day.
