What this is, in plain language
Surgery that removes a cloudy natural lens from the eye and replaces it with a clear artificial lens, using ultrasound to break up the old lens through a tiny incision.
Why a clinician orders it
A cataract causing vision problems that interfere with daily life — glare, trouble reading, or difficulty driving at night.
Medical necessity — what insurers usually look at
Insurers require documented visual impairment affecting daily activities, usually with a visual acuity measurement. Premium lens upgrades (multifocal or toric lenses) are often NOT fully covered — ask about out-of-pocket costs for lens options.
