It is possible for people to develop cataracts in both eyes. Thankfully, the surgery to remove cataracts is relatively simple and straightforward. Your doctor will likely perform two separate surgeries if you have cataracts in both eyes.

Cataracts are the degeneration of the cells inside the human crystalline lens. Most cataracts are caused by aging and the natural deterioration of the body's tissues. Hence, this degeneration happens within both eyes at the same time and most people have bilateral cataracts developing at the same time. It is common for one to be more advanced and interfering with vision ahead of the other. This causes surgery to be performed in the worst eye, sometimes years before the other eye is ready.
Cataracts that are caused by other than aging (trauma, inflammation, birth defect etc.) can be very asymmetric, such that the other eye may be decades away from surgery.
