I've been extremely myopic since birth. For 3 years my right eye has been 'blinder' to the point of uselessness from cataracts. Surgery yesterday means that for the first time since 1969, i can see with an eye! (snoopy dance).
Also, I'm old enough that my other lens is yellow. My new crystal lens is clear. So if i look at white with my left eye, it is yellow. But everything us perfect in the right eye. Though a little exhausted from not being used for over 3 years...
