Femtosecond facilitates 'big bubble'

Dr. Buzzonetti, chief, Department of Ophthalmology, Bambino Gesù Hospital, Rome, described his new "IntraBubble" technique in which he uses a proprietary femtosecond laser (IntraLase, Abbott Medical Optics) to create an intrastromal channel that is used as a pathway for the insertion of the air injection cannula.

Thanks to the accuracy of the femtosecond laser, he said, the channel terminates at a predictable depth that optimizes the plane for air injection while minimizing the risk of perforating Descemet's membrane and making the insertion of a smooth, flat, 27-gauge cannula easier and safer.
