Hello.
Dont worry!
I put up with 2 years of lasering every month. Sometimes 1000 zaps a session before having a vitrectomy. Were the membrane or jelly is removed completely. This removes the area that blood flows into and obstructs your vision. The replace the membrane wih an oil or a gas. Since ive had this surgey, my retonopathy has slowed down complwtely and bothers me a lot less. The surgery can be done as a day case though. The major inconviniece was having to lie face down for 2 months whilst it settled. Dont wory about it. Ive had 5 eye surgeries. I even did one under local anaesthetic whilst awake, but once was enough. General is much more preferable to me.
