Same thing happened to me. I was told it was common after cataract surgery. Laser treatment helped only a little. Some time later I was having my regular eye test and when reading the chart everything was blurry and wavy in one eye. Diagnosed as an Epiretinal membrane. Possible solution is surgery but not always successful, I was advised not to do it by a retinal specialist. It seems to be getting worse, so of course I am worried. I read on the web that it can be a result of having cataract surgery, I have an appt. with the specialist in late June. I'll report back here afterwards if you are interested.
