Dr. Smith performs a minimally invasive, no-stitch cataract surgery called phaco surgery. A tiny incision (3.2 mm or less) is made in the eye and a small ultrasonic probe is inserted. This probe breaks up, or emulsifies, the cloudy lens into tiny pieces and gently sucks, or aspirates, those pieces out of the eye. Then a new artificial lens called an IOL is implanted in the eye.
