Surgery is performed when the cataracts cause vision changes that interfere with your daily life.
Over time the clouded areas of your lens can become larger and denser, causing your vision to worsen to the point of not being able to see a hand moving in front of your face. This can take months to many years.
Once a cataract has been removed, it cannot return. Over time, some patients may notice that their vision has once again become cloudy. This is sometimes called a “secondary cataract.” This is not an actual cataract, but rather a cloudiness of the natural lens capsule of the eye which supports the intraocular lens. Your ophthalmologist can perform an outpatient laser procedure (Yag capsulotomy) to clear the cloudy capsule.
