I have a cataract

Symptoms and complications

Very common, cataract is the leading cause of surgery in France (about 450,000 interventions each year). This gradual opacification of the lens (the lens inside the eye) appears with age: it affects more than half of people over 65, and more than two thirds of those over 75 years, regardless of sex. Without treatment, cataracts can cause loss of vision: it is the third leading cause of blindness in France after age-related macular degeneration (AMD) and glaucoma.

What are the symptoms of cataracts?

Cataract is so called because it was said that its symptoms evoked the vision that can be seen looking through a waterfall. Cataract is a disease that evolves gradually, its symptoms appear gradually.

Cataract is characterized by a progressive loss of vision, which most often affects vision from a distance. This opacification of the lens located inside the eye usually takes several years to prove embarrassing: the person becomes slightly myopic (unless it was hyperopic before, in which case his vision from afar tends to improve! ) and the colors appear duller (but the brain tends to compensate for this phenomenon).

Little by little, vision becomes cloudy and the person becomes more sensitive to light (photophobia): people with cataracts that become symptomatic often complain that they are easily dazzled by the light from the headlights while driving at night. Sometimes the person complains about "seeing double" with one eye.

In rare cases, the onset of cataract symptoms may be faster (a few months).

What are the complications of cataracts?
When left untreated, the cataract becomes progressively worse. The lens becomes more and more opaque and the person ends up completely losing sight.

In addition, in some cases, cataracts cause an increase in the volume of the lens that can lead to the development of acute glaucoma. Sometimes it happens that lens proteins leak into the anterior chamber of the eye: these proteins can clog the trabeculum and cause chronic glaucoma, or be the cause of an immune reaction that will trigger inflammation of the eyes. internal structures of the eye (uveitis).
