Some minor cataracts that do not cause significant visual loss do not require treatment. Instead, careful monitoring for progression is generally advised in these cases. Cataract surgery is advised if a cataract progresses causing significant loss of vision. Regular monitoring is vital because if progression is noted, early surgical intervention leads to the best success rates.

There is no medical treatment for cataracts, but sometimes, there is concurrent inflammation in the eye. This may require anti-inflammatory drops to prepare the eye for the operation or to prevent other potential problems that can arise if cataracts are not removed (e.g. glaucoma).
