I have read community members' comments on this site for a few years now, and they mention results all along the spectrum. Some people see an improvement in their vision; sometimes a big improvement. Others see a small improvement. Some see no improvement at all. The main object of the shots evidently is to hold the sight steady. I think the variations in results can come from a number of factors such as: how early the treatment was started, what medication is used, whether scar tissue develops. Sometimes results are achieved quickly and for others it takes a long time. The medication in the injection is sometimes changed if it isn't working. I'm not a medical person - these are the comments I've read from our community which might help you. Warm wishes, Wendy, Patient Leader.
