A cataract is a clouding 
or opacification of your normally clear lens of your eye. Patients with cataracts perceive filmy or cloudy vision, as if they are looking through a dirty windshield. Some patients require a lot of light to read. Some experience glare and haloes around lights or see double or multiple images. Increased age, trauma, certain medical conditions, and steroid use are the main risk factors for developing cataracts.
Cataract surgery is usually considered when it impairs your ability to function in one’s daily life activities. Today, cataract surgery is an outpatient procedure that typically takes fifteen to twenty minutes. The cataract is replaced with an intraocular lens. There are various intraocular lens options depending on visual goals and needs.
