For the majority of cases, surgery is the only cure. Modern cataract surgery is typically performed through a small incision. High-frequency ultrasound, called phacoemulsification, is used to break up the cloudy lens material, and a micro-vacuum removes it from the eye. A clear, artificial implant lens of appropriate power is placed inside the eye to provide focusing power. Today, no-stitch cataract surgery is performed whenever possible.
Before the procedure can begin the pupil is dilated, and the surgical area is prepared using a sterile cleanser. A topical anesthetic is then administered to the surface of the eye. An incision of 2.5 to 3 millimeters in length is then created at the junction of the cornea (the clear front of the eye) and the sclera (the white part of the eye).
