Rejuvenating cataract surgery with a simple device – miLOOP – and ensuring it reaches those who need it most

At a Glance
- We have exploited the shape memory properties of nitinol to develop a simple and efficient cataract fragmentation device in a single-use, disposable format
- The miLOOP comprises a nitinol filament mounted on a pen-type actuator, and enables rapid non-thermal cutting of even the hardest cataracts without vibrational, laser or heat energy, and with no fluidics complications
- In consequence, miLOOP cataract surgery is faster and more efficient particularly in the context of grade 3 and 4 cataracts; furthermore, low cost and ease of use make it a viable option for both emerging and developed markets
- The way is now clear to address the 25 million cases of cataract-associated blindness seen each year in the developing world, and to improve the efficiency and safety of cataract surgery in the developed world.
Microinterventional technology in surgery isn’t new; our colleagues in the cardiovascular and interventional radiology fields have been using microstents and similar devices for about 40 years. Ophthalmic surgery, however, has generally failed to benefit from these developments. But things are changing – in glaucoma, for example, we’ve seen dramatic advances associated with the advent of MIGS. Nevertheless, in cataract surgery, we’re still using the capsulorhexis and chopping tools that we were using 20 years ago. I believed that it was time to rejuvenate this field, and so I developed miLOOP – a simple, low-cost device for microinterventional cataract surgery.
