are you on prednisone? and if so do you notice a difference in day vs night vision? (day being much worse in my case)

If both of those were a yes then you may or may not have cataracts. Those were the two biggest things that made my diagnosis of that so easy. That and the huge white thing in my pupil when they dilated it.

If thats the case it really isnt a huge deal especially coming off of something like a thymectomy. I Just had the surgery on both of my eyes a couple months ago. You go in the morning get the lens put in and walk out that morning, come back for a follow up with the surgeon and do the same thing a week later. Those two weeks are a little trippy with your depth perception being all whacked out and one of your eyes being covered while your out and about. but other than that its super easy compared to the thymectomy.
