La Phacoemulsification with ultrasonic energy is most commonly used technique for cataract surgery. Ultrasounds literally "pulverize" the cataract and this allows surgery to be performed through very small incisions (2 mm), aspirating its contents and thus reducing surgical trauma. In our case, we use micropulsed ultrasound with bimanual technique, a procedure that involves a upper step since it allows even smaller incisions, less than 1 mm, with less surgical trauma. The result of this technique is a safer surgery and with a faster recovery. Modern cataract surgery consists of emptying the “crystalline sac”, taking advantage of its configuration to house the intraocular lens that will allow us to recover our vision in the following days.
