Hi
@JackBux and welcome
I'm sorry you're having to deal with retinopathy, there are treatments that can slow or halt its progression. It is frightening when you are told you need laser but the whole aim is to stop the damaged areas in the retimas increasing and to protect as much stable sight as possible. Stage 3 retinopathy is also called severe non proliferative retinopathy
I had maximum laser in both eyes. I was late to be diagnosed as there was no retinal screening programme back in the 1980's early 90's. Starting any treatment in good time is the best way to try and keep as much sight as possible.
I had a number of sessions of laser on my peripheral retinas before I started to notice any reduction in my sight. The rod cells in peripheral vision deal with night time and low light vision and after a few sessions of laser I started to notice I struggled in the dark. You have a certain number of laser burns to seal off the areas of haemorrhages at each appointment- be prepared for more than one appointment as there is a limit to the number of laser burns that can be applied each time to prevent inflammation and swelling in the retina. It doesn't mean you will immediately notice loss of peripheral vision, hopefully the early intervention will stop the retinopathy from progressing and you will return to monitoring.
Be prepared with sunglasses as eyes can feel gritty and very light sensitive after treatments but this does settle down over the following days.
I find the information on this site really useful for all things retinopathy. It does all sound scary but there is so much that can be done to stop damage progressing.

What is your diabetes control like? HbA1c, blood pressure, cholesterol etc. If you have a higher HbA1c please discuss the safest way to reduce it slowly with your team as perversely rapidly reducing your HbA1c can speed up the progression of retinopathy which is the last thing any one needs in this situation.
Wishing you well, happy to help if there's something I've missed out!
