Submission + - Followup: Ultraviolet Vision after Cataract Surgery (komar.org)

xmas2003 writes: "Several months ago, I posted to /. about being able to see ultraviolet light after cataract surgery. While a lot of the discussion whimsically discussed the best way for "Captain UV" or "UltraMan" to use this "super-power", there were some people who were skeptical or (incorrectly) said this is Tetrachromatic vision. I've subsequently done more testing using an Oriel Instruments MS257 Monochromator and was able to see color down to 350nm — below the usual ~400nm limit of the visual spectrum. It's also easily demonstrable with a pair of 400nm and 365nm UV flashlights.

Some /.'ers who also have UV vision commented this can be quite annoying at black-lit Disney Rides, Halloween Haunted Houses, etc. Fortunately for me, it's just an interesting oddity so far. Along those lines, some interesting related stories about using UV vision during World War II and Star Gazing. Finally, many/most people end up getting vision debilitating cataracts, so my experience having a Crystalens implanted after cataract surgery may be informative."

Submission + - Cataract Surgery: Research & Firsthand Experie (komar.org)

xmas2003 writes: As a long-time reader of News for Nerds, I fit the "profile" in a number of ways — including being myopic since childhood ... but fortunately for me, this was correctable with glasses or contacts. Around age 40, it started becoming more difficult to do close-up tasks (such as using vi to edit Perl code ;-) as Presbyopia showed up right "on time" — I'm sure many older /. readers can relate.

But at age 46, a cataract started to obscure my vision which was no longer correctable — bummer to have this happen a few decades early. After extensive research on the various options (mono focal, multi-focal, accommodating, etc.), I opted for Cataract Surgery with a Crystalens implant.

Millions of Cataract Surgeries are done annually, so I figured my (overly analytical) writeup plus visual examples might be of interest to some /. readers who may (or will) be dealing with the same issue. Plus I'm sure many have gone through this process and can chime in with their experience/recommendations.

I had the first eye done last Monday and have been updating the web page — so far, so good. The eye doctor will "poke a hole" in my second eye this Monday — wish me luck! ;-)
