How do diabetics get cataracts?

How can diabetes contribute to cataracts? The lens of the eye gets oxygen and glucose from the aqueous humor, which is the fluid that fills the front of the eye. If someone doesn’t have control over their glucose levels – such as someone with diabetes – the sugar levels can rise, causing the lens to swell.

How long does it take for diabetes to damage eyes?

Neovascular glaucoma can occur if these new blood vessels grow on the iris (the colored part of the eye), closing off the fluid flow in the eye and raising the eye pressure.

What are the 3 types of cataracts?

A cataract is a clouding of the lens of the eye that impairs vision. There are three main types of cataract: Nuclear Sclerotic, Cortical and Posterior Subcapsular. The types of cataracts are classified based on where and how they develop in the eye.

What is the recovery time after cataract surgery?
