Phacoemulsification

Phacoemulsification ("phaco") was developed in the search for a way to extract cataracts through a smaller incision. It has become the preferred technique for cataract extraction. An ultrasound or laser probe is used to break the lens apart without harming the capsule. These fragments are then aspirated out of the eye. A foldable intraocular lens (IOL) is then introduced through the 3mm incision. Once inside the eye, the lens unfolds to take position inside the capsule. No sutures are needed, as the incision is self-sealing. The risk of astigmatism and sudden pressure changes inside the eye are minimized. The procedure is safe enough to be done under topical anesthesia (anesthetic eyedrops). Visual rehabilitation is extremely fast and patients don't need to suspend their everyday activities.
