I have been getting injections for 3 years as well. I started out with Bevacizumab (Avastin), then later changed to Ranibizumab (Lucentis) and then lastly to Faricimab-svoa (Vabysmo). Each time it was explained to me why and what the differences might be for me, I was also given the manufactures literature and time to ask questions and talk about it if needed. Each time the shots were changed there was some improvement. The procedure stayed the same for each shot, the only other difference for me is the Vabysmo feels a little thicker. Really pretty much the same experience for all the shots. I would discuss any changes with my doctor and ask questions about the change is shots. To me this should not be a mystery about what is going on with eye treatments and progress.
