Had a very similar experience to yours - except they did one eye at a time, six weeks apart.  They covered the operated on eye with a bandage for 24 hours and when they took the first bandage off I was shocked at the colors that I could see with my "new" eye and lens.  Colors had slowly faded away from the cataracts over the years.

Prior to my surgeries I had to wear glasses all the time but now - four years after the surgeries, I still only need glasses for reading.  A couple of times during the first two years after surgery my vision became blurry in one eye and each time I'd go to the doctor and he'd give me a laser treatment in that eye and it would clear up immediately.  It was something covering the lens.

My dad had cataracts in the days before the plastic lens insertion and in those days to have the cataract removed meant becoming almost blind and having to wear glasses with very thick lenses.  He learned about eye exercises for reversing cataracts and did them faithfully on a daily basis and actually improved his vision and reversed the cataracts to some degree.  With today's technology I didn't even consider eye exercises.
