I had my second cataract op 8 weeks ago, right eye this time which is my prefered obseving eye. My first op, on the left eye, was 4 years ago and the diference to my eyesight was amazing. Colours became brighter and whites were much more pure as the cataract imparts a light sepia colour to the vision. At first, a darkish crescent shape shadow was present at the very corner of the eye but soon disappeared. Rainbows were also present around bright lights. Recovery took about 2 weeks.
At the telescope, after I got used to using my left eye instead of the usual right one, I noticed a substantial increase in colour perception and perhaps more contrast also. The right eye got progressive worse so I decided to go for the second op as it was becoming more difficult to drive at night. This time a laser was used to do the initial incision and 'loosen up' the cataract. Recovery this time round was quicker and, so far, no side effects. I can now go back to observing with the right eye. Next time I'm in a dark sky location I'll do a star count to ascertain if I can go half a magnitude fainter using both eyes...
