During cataract surgery at our Chicago, Illinois practice, the cataract is removed from the eye using the phacoemulsification technique. Performed on an outpatient basis, our cataract surgeons use local anesthesia or apply anesthetic eye drops. Utilizing sound energy waves, the cataract is dissolved into microscopic particles. Next, the surgeon will remove the particles from the eye. Cataract surgery requires a small, self-healing incision, and an implantable lens such as crystalens® or ReSTOR® will be inserted to replace the natural lens of the eye.
