FluidVision: Designed to Restore True Accommodation
PowerVision’s fluid-controlled accommodating intraocular lens (IOL) is “the first true shape-changing lens that mimics the eye’s natural accommodative process,” said co-founder, president, and chief executive officer Barry Cheskin. The FluidVision lens, therefore, creates a continuously variable monofocal designed to restore “true accommodation,” he said.
“When the eye moves to a natural accommodative state, the capsular bag squeezes the fluid in the lens one way, from the haptics to the periphery of the IOL, inflating the lens and providing near vision. When the eye moves to its disaccommodative state, the capsular bag moves fluid in the opposite direction, deflating the lens and creating distance vision,” Cheskin explained.
Studies presented at the European Society of Cataract and Refractive Surgeons (ESCRS) in September 2016 indicate the fourth-generation FluidVision lens is providing “excellent, stable outcomes” and has a proven accommodative function without compromising capsular bag integrity or clarity with results out to 36 months.
FluidVision’s “speed of response is a key driving factor,” the CEO noted. “This lens has been shown to be as fast or faster in accommodative response than a healthy 29-year-old eye.”
The FluidVision lens has evolved over its development; the current generation is in single center and multicenter studies, and incision size has been reduced from 4.0 mm to 3.5 mm.
PowerVision next expects to begin studies on the FluidVision 20/20; Cheskin promised the lens will provide “twice the accommodation and give 20/20 across all distances.” Initial bench testing suggests the FluidVision 20/20 can provide much crisper vision than even the most advanced multifocals from 0.0 D to 3.0 D of accommodation.
“Next we want to go to a 3.2 mm incision, then to a toric version, then to post-implant adjustment and a 2.8 mm incision,” Cheskin said.
