Most people who have cataracts do not have diabetes. Diabetics are more likely to have them but many diabetics do not get them. I had diabetes about 50 years befor I had cataracts. My surgeries, were simple and there was no problem at all. It is done as an outpatient surgery, then my wife drove me home.The doctor told me I had the start of Cataracts. He said I need to check for diabetes. Last year my blood sugar was 75 fasting.. Would I have had to have diabetes for a while to get cataracts or does cataracts come on quickly if you just developed diabetes?
