Cataract surgery has advanced significantly with improvements like phacoemulsification that uses ultrasound to break up the cataract. This technique allows for a smaller incision and faster recovery compared to previous extracapsular cataract extraction surgery. Newer intraocular lenses and technology have also improved vision outcomes and the ability to reduce dependence on glasses after surgery. Cataract surgery is now a very common and highly successful operation.
