Just giving you all my personal experience of using Avastin, I find this treatment to be fantstic for me, as stated before I was against laser surgery and was lucky enough to have a great opthomologist who had his finger on the pulse and knew about Avastin.
I have 7 injections since 2008 and no need for any laser surgery as yet. As far as I know it can also be used for other eye problems.
I must add that I am using this purely for PDR and am lucky enough (at present) not to be suffering with any swelling or loss of vision. Avastin will not restore sight.
The injection takes a couple of seconds and the thought of it is far worse that the actual proceedure, my eyes are basically back to normal the next day so it's off to work I go!
If anyone has the chance to try this, despite it costing a bit, then I would highly recommend it
