There is an article in the September 2014 issue of Sky & Telescope magazine called, "Cataract Surgery for Astronomers".
I think it has an important bearing on us as photographers as well. It is well worth reading and explains some things to be aware of and ask your doctor about.
If anyone wants, contact me with you e-mail and I'll send a couple of PDF files I scanned of the article. (had to break it into 2 files to get it small enough to e-mail)
