Continuous Curvilinear Capsulorhexis in Cataract Surgery Using a Modified 3-Bend Cystotome

Figure 2

Schematic diagram of 3- and 2-bend cystotomes.

(a) Schematic diagram of 3-bend cystotome: a 3-bend cystotome mimics the human arm, with the middle bend acting at the position of the elbow; the posterior arm conforms to the angle of the posterior lip, and the ACD is still kept stable when the anterior arm drives the tip to perform a CCC

(b) Schematic diagram of 2-bend cystotome: the conventional 2-bend cystotome has one straight arm only, which inevitably presses the posterior lip when performing a CCC, allowing the viscoelastic agent to escape and failing to sustain the ACD
