Furthermore, we can take the lens section out very easily, so we can come back five years after implantation and exchange it if something better comes along.”Sumit Garg, MD, vice chair of clinical ophthalmology, medical director and an associate professor of cataract, corneal and refractive surgery at the Gavin Herbert Eye Institute at the University of California, Irvine, agrees that Juvene being a modular lens is advantageous. Garg is also a consultant to Lens Gen.) “The two-part lens consists of a fixed ‘base’ lens and a fluid-filled ‘power’ lens,” he notes.

“In early clinical trials, the lens delivered up to 3 D of continuous range of vision, with minimal or no visual side effects.

Here’s the latest on the three frontrunners that may give surgeons a true accommodating lens in the years ahead.

The Juvene The Juvene accommodative IOL (Lens Gen, Irvine California) was recently profiled at the annual meeting of the American society of Cataract and Refractive Surgery by Eric Donnenfeld, MD, a clinical professor of ophthalmology at New York University Medical Center and a partner at Ophthalmic Consultants of Long Island. Donnenfeld is a consultant for Lens Gen.) He implanted his first Juvene in March of 2018, in Santa Domingo in the Dominican Republic.

“Because it fills the capsular bag there’s no change in the effective lens position and no rotation when it’s implanted,” he says.

“There’s no posterior capsular opacification, and there are fewer flashes and floaters because the vitreous face doesn’t come forward.

There are no major contraindications, because it functions as a monofocal lens.

There’s no splitting of light, so you don’t have to worry about any loss of contrast sensitivity.”Dr.

Garg adds that he’s had the opportunity to implant a few of the Juvene IOLs.

“They had excellent intermediate vision, and about half of the patients ended up seeing 20/32 at near. Donnenfeld also says that four-year data is now available for the first patients implanted with the lens. “None of them developed posterior capsular opacification, because the leaflets of the capsule are separated.” Asked about similarities to the Fluid Vision accommodating lens (see page 16), Dr.

Donnenfeld notes that they share the same type of mechanism.
