Earlier cataract surgery was performed by a method called extracapsular extraction, which involved longer incision of 10 mm or almost half the eye. Recovery meant a week-long hospital stay after surgery and limited physical activity for weeks or even months. Charles Kelman created phacoemulsification in the late 1960s. His goal was to remove the cataract with a smaller incision, leading to lesser pain and shorter recovery time. He discovered that the cataract could be broken up or emulsified into small pieces using an ultrasound tip. With the procedure’s success rate and shorter recovery period, over the past decades, surgeons have constantly refined phaco by continuously reducing the incision size (currently it is 2.8-3.4 mm) thereby, making it even safer and more successful. |
