Zepto, also referred to as “precision pulse capsulotomy," is an automated anterior capsulotomy device consisting of a disposable handpiece and capsulotomy tip powered by a small console. The cutting element is a nitinol ring surrounded by a thin, transparent silicone shell with a central opening which allows patients to fixate on the microscope light filament during positioning. After the nitinol ring and silicone shell are stretched and elongated with a metal push rod to facilitate insertion through a clear corneal incision, the tip re-assumes the original circular shape and is gently apposed to the anterior capsular surface with suction. A series of rapid electrical nanopulses cleave 360º of the apposed anterior capsule in milliseconds.
The ApertureCTC consists of a power console, reusable handpiece, and disposable capsulotomy tip that uses thermal energy to create an anterior capsulotomy. The circular heating element is mechanically retracted to form an elliptical shape to enable insertion though >1.8 mm incision. Upon release, the heating element reassumes circular shape and is placed on the anterior capsule over the desired capsulotomy site. A patented algorithm deliver continuous, controlled low-level energy throughout 360º of the heating element.
CapsuLaser device consists of a power console and a small, ergonomic laser delivery device that mounts to the operating microscope. The device delivers continuous laser energy in a singular circular pass to create a continuous curvilinear capsulotomy in approximately 1 second. After staining the anterior capsule with trypan blue, the aiming beam is focused through a handheld contact lens and laser delivery is activated through a footswitch.
