ZEISS miLOOP to remove the challenge of dense cataracts


Removing the challenge of dense cataracts.

The miLOOP® from ZEISS is a game-changing microinterventional lens fragmentation device which is designed to remove the challenges of hard cataracts. Using micro-thin super-elastic, self-expanding nitinol filament technology, the ZEISS miLOOP allows cataract surgeons to achieve zero-energy lens fragmentation for any grade cataract.1

Reduced phaco energy and fluid use

Minimal stress to capsule and zonules

Reduced procedure and post-op treatment time

Significantly reduce overall phaco energy and fluid use for dense cataracts

A randomized controlled study in the British Journal of Ophthalmology showed that using ZEISS miLOOP in hard grade 3-4+ nuclear cataracts reduces phaco energy by up to 53% and therefore also ultrasonic vibrations. The same study also confirms that using ZEISS miLOOP significantly lowers the surgical irrigation fluid volume used per case by up to 30%.1

Apply minimal stress to the capsule and zonules

ZEISS miLOOP is engineered to minimize capsular and zonular stress. It allows out-in nucleus disassembly that directs the force used to divide the lens inwards, while conventional techniques employ in-out lens cutting with adjunct phaco-energy.1

Reduce procedure and post-operative treatment time

In a 2019 surgeon survey, the majority of trained ZEISS miLOOP surgeons report a perceived reduction in overall procedure time with ZEISS miLOOP.2 Furthermore, ZEISS miLOOP usually results in less trauma to the capsular bag and zonules thereby potentially reducing the need for additional post-operative treatment.1,3

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.4,5,6,7,8 Thus, the ability to significantly reduce the overall phaco power by using ZEISS miLOOP1 may decrease the number of related complications that need post-operative treatments.
