Novel IOL technology promises accommodation without movement, speaker says
ORLANDO, Fla. — The first electro-active diffractive liquid crystal IOL promises to provide accommodation without anatomic or mechanical movement, a speaker said here.
Components of the implant are currently available, Jay S. Pepose, MD, PhD, said at the American Academy of Ophthalmology meeting.
"Consistent performance of accommodating intraocular lenses are impacted and influenced by individual variations in the diameter of the capsular bag, variable capsular shrinkage and fibrosis, and systemic drug effects on ciliary muscle contraction," Dr. Pepose said. "A lens that could accomplish accommodation or a change in dioptric power without requiring movement can obviate some of these problems."
The basic technology enabled the development of spectacles that have a dynamic addition component that uses an electro-active lens.
Elenza is embarking on development of the first electro-optic diffractive IOL.
Proposed design features of a prototype in development include a monofocal static IOL with a central aspheric modification to allow far and intermediate vision, an additional smart electro-active diffractive liquid crystal lens for near, microsensors to detect physiological triggers of accommodation, and onboard processors and algorithms to control the power sequence.
Accommodation would trigger an additional 2 D to 2.5 D of power at near Lithium ion power cells would be recharged weekly by an inductive charging element. Microsensors detect difference in illumination with miosis and use dual application-specific integrated circuits, Dr. Pepose said.
