Watch as Rodney Kellen, MD of Winnipeg, Manitoba, Canada, creates a perfectly sized and centered capsulorrhexis with the aid of Katena's Kellen CCC Marker (K3-7850 or K3-7852). This marker is designed for impressing a circular pattern on the cornea to serve as a guide for performing a 5.5 to 6mm diameter capsulorrhexis. The marker features a diameter marking ring with four symmetrically placed, non-marking pegs extending to the 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.
