How long do cataracts last?

Forever: A cataract is clouding of the lens of the eye. Once this occurs the only treatment is surgical removal of the affected lens. The decrease in the vision that a cataract causes happens over months to years typically. Someone can go for years before needing to have the cataract removed.

Until treated: Most cataract occur later in life and gradually progress if untreated. Some congenital and traumatic cataracts of earlier life are static and may last a lifetime without change. Given the success of modern cataract surgical removal, you should have your ophthalmologist evaluate your cataract for treatment potential. Not something an optometrist can do.

Cataracts: Cataracts are life-long. They do not go away - except with surgery.

Till removed: Not all cataracts require surgery. If best vision is worse than 20/40 or glare is significantly affecting VA, most surgeons prefer to do surgery sooner but depends on pt's sx, risk factors, preferences; also, though no guarantees with any surgery, many patients are less dependent on or free of glasses after surgery; clear lens removal also possible in some pts; info: eyedoc2020.blogspot.com
