Dear Jackie100,
I'm not sure what you know about a Vitrectomy or what you've been told what it is but this might help
What Is a Vitrectomy?
It's a type of
eye operation. A doctor removes the vitreous, a jelly-like fluid inside your
eye, and replaces it with a saline solution.
Why Do You Get It?
For you to see, light has to pass through your
eye and reach your retina, the bundle of tissue at the back of your
eye that senses light. It sends the information to your
brain.
Various diseases can cause fluid in the vitreous to cloud, fill with
blood or debris, harden, or scar. This can keep light from reaching your retina properly and cause
vision trouble. Removing and replacing the fluid may solve or improve the problem.
Sometimes the retina pulls away from the tissue around it. Your doctor could do a vitrectomy to make it easier to get to your retina and repair it.
It can also give your doctor access to your
macula, which lies at the center of your retina and provides sharp central vision. A hole in it can result in blurry
vision. With the vitreous fluid gone, it’s easier to fix
As for your question as to whether you would loose your driving licence, i and no-body else can say, but it's very unlikely that this will happen from the statistics that I've found. This is a relaively straight forward procedure and you should come through it with improved vision according to everything that I've unearthed on this.
do't worry unduly, this procedure is common these days. Please let us know how you get on.
