Second-wave hydrodissection for aspiration of cortical remains after femtosecond laser–assisted cataract surgery

摘要

We describe the technique of second-wave hydrodissection (the first wave being the initial cortical cleaving hydrodissection) performed after the removal of the cataract nucleus in femtosecond laser–assisted cataract surgery. After femtosecond laser application, the cortex is typically found adhered to the anterior capsule. Under high magnification, a steady stream of a balanced salt solution is directed toward the anterior capsule using a hydrodissection cannula. Full cleavage of the remaining cortex is observed by noting the appearance of a dark inner circle by the capsulotomy edge once the balanced salt solution wave has separated the cortex from the capsule. Irrigation/aspiration (I/A) of the cortical remains after the second wave is faster than I/A without this step in femtosecond laser–assisted cataract surgery.
