Vitrectomy is a surgery to remove the vitreous gel from the middle of the eye. It may be done when there is a retinal detachment or if blood in the vitreous gel (vitreous hemorrhage) does not clear on its own. Removing the vitreous gel gives your eye doctor better access to the back of the eye. Vitrectomy is done by an eye doctor who has special training in treating problems of the retina.

A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night. This may result in trouble driving, reading, or recognizing faces. Poor vision caused by cataracts may also result in an increased risk of falling and depression. Cataracts are the cause of half of blindness and 33% of visual impairment worldwide.
