The lens fragmentation device is a snare that captures cataractous lenses and facilitates their disassembly with low energy use and fluidics.

A micro-interventional device designed to deliver zero-energy endocapsular lens fragmentation (miLoop, Carl Zeiss Meditec) serves as an aid during cataract surgery to remove even the hardest cataracts safely.
“The [lens fragmentation device] is essentially a modernized snare that differs from similar devices because it is sterile and does not require assembly,” said Alan S. Crandall, MD.
The device—made of highly elastic, memory-shaped thin filaments—allows full-thickness lens fragmentation at low-energy levels, said Dr. Crandall, the John A. Moran presidential professor; senior vice chairman; director of glaucoma and cataract; and director, Moran Outreach Division, John A. Moran Eye Center, University of Utah, Salt Lake City.
A study in which the device was used during phacoemulsification and compared with manual phacoemulsification alone—the LEEP 103 study—evaluated energy delivered and fluidics.
Results showed that less fluidics and energy were needed—the fluidics and energy used were 27% and 53% higher, respectively (p < 0.05 for both comparisons).
