Removing the challenge of dense cataracts.


After they tried the miLOOP® from ZEISS in their OR, we asked surgeons what they think about it. Here’s what they said.

What is ZEISS miLOOP?

The ZEISS miLOOP is a microinterventional lens fragmentation device. Using micro-thin super-elastic, self-expanding nitinol filament technology, ZEISS miLOOP allows cataract surgeons to remove the challenges of hard cataracts.

  • Reduce phaco energy by up to 53% for grade 3-4+ nuclear cataracts1
  • Lower the surgical irrigation fluid volume used per case by up to 30%1
  • Apply minimal stress to the capsule and zonules1
  • Reduce procedure and post-operative treatment time2

  • 2 The majority of trained ZEISS miLOOP surgeons report a perceived reduction in overall procedure time (internal user survey, n=279, Iantech Data Analytics 20190708 PPT, data on file). Furthermore, ZEISS miLOOP usually results in less trauma to capsular bag and zonules (see source 1) thereby potentially reducing the need for additional post-operative treatment (see source 3). Additionally, ZEISS miLOOP may reduce the likelihood of needing time-consuming post-operative treatments: One of the major causes for endothelial cell loss in cataracts with increased density is the amount of phaco energy emitted into the eye during surgery (see sources 4,5,6,7,8). Thus, the ability to significantly reduce the overall phaco power by using ZEISS miLOOP (see source 1) may decrease the number of related complications that need post-operative treatments.
