Kellen Capsulorrhexis Marker
for producing a centered, predictably sized capsulorrhexis

This new marker has been designed to impress a circular pattern on the cornea which serves as a guide for performing a 5.5 to 6mm diameter capsulorrhexis. The marker consists of a 6mm diameter marking ring with four symmetrically placed, non-marking pegs extending to the 11mm optic zone. A perfectly centered mark on the cornea is created by aligning the pegs with the limbus and gently pressing the ring onto the corneal surface. Using this mark as a guide, the surgeon can produce a centered, predictably sized continuous curvilinear capsulorrhexis. The instrument is particularly useful when the pupil dilates eccentrically and the usual cues to center the rhexis are absent.
