  • Open C-shaped loop with staggered indentations to facilitate cortical removal
  • The 12.10 mm diameter ring compresses to 11 mm after insertion
  • Available preloaded on an EyeJet or can be inserted manually or with Geuder Injector

The Henderson CTR (HCTR), designed by Bonnie Henderson, MD, is a modification of the standard CTR that features indentations for easier nuclear and cortical material removal while still maintaining the desired stretch of the capsular bag. Once the residual material has been removed from under the indentations the Henderson CTR can be rotated to allow further removal of lens material that was previously compressed by the protruding notches.

  • The only Cionni CTR preloaded on an EyeJet and in a clockwise injection mode
  • Diameter is 11 mm
  • Specially indicated for severe or traumatic zonular dehiscence or dialysis with pupil abnormalities whenIris Retractors and other CTRs cannot achieve capsular stability.

The Malyugin/Cionni CTR features a curved end designed to eliminate risk of perforating the capsular bag by allowing the leading end of the CTR to slide along the equator of the bag. The eyelet at the curved end is sutured to the sclera for secure fixation and offers an alternative to capsule supporting hooks.
