Familial pre-senile Cataracts young adults

I was diagnosed with cataracts, fast progressing yellow cataracts at 29, my sister had hers diagnosed around the same age. My Dads whole family, bros. and my grandmother were diagnosed in their early years as well, back in the early 1900's. When I first thought my windshield was dirty I thought I scratched my eye, and went to my Dr. who sent me to a ophthalmologist, who told me..you have cataracts...have you been exposed to radiation or steroids? he asked. I said no..but my Dads whole family had it when they were young too...okay he said..its familial...okay..so I told my Dad...you are my Dad! That was almost 30 years ago. I have had my implants for 28 years. My sister as well. I was lucky.

They had just approved implants in people younger than 50 about 5 years previous to my surgery's so there was no arguments. My sisters experience through another health care provider wasn't as friendly. They wanted to be sure she wasn't exposed to radiation and steroids and almost did not believe her story about our Dads family...
needless to say....why even worry or concern myself with this? well we have had other unexplained issues with auto immune issues and other eye issues as well. So not to worry, or worry I guess to what end?

I guess what I want to know is this...and this is a pretty precise question....on the DNA strand where this is, what other issues can we expect? What other DNA issues will there be that are carried on the DNA strand that carried our pre-senile cataracts?
Would love to hear other stories as well. I also have corneal dystrophy and of course eye strain because my eyes have evolved to being mono- focular, so one is far and one is near...end result, glasses and eye strain chronically. Anyone else out there? I
