Carl Zeiss Meditec introduces trifocal IOL for enhanced vision
MILAN — Carl Zeiss Meditec introduced the trifocal At Lisa tri 839MP IOL, based on the established At Lisa platform, at the European Society of Cataract and Refractive Surgeons meeting here.
“We would like to assist our customers in optimally addressing the challenges of surgical cataract and presbyopia correction,” Ludwin Monz, MD, president and CEO of Carl Zeiss Meditec, said in a press release from the company. “With the At Lisa tri trifocal IOL, this means that patients are provided with the most natural postoperative vision possible without being reliant on eyeglasses.”
The lens allows patients to “switch almost naturally” among near, intermediate and far vision without spectacles, the release said. The IOL has an asymmetrical light distribution between three different foci, at 50% far, 20% intermediate and 30% near.
Contrast sensitivity rate is maintained by increased light energy transmittance, while the lens offers a lower visual disturbance, the release said.
“At Lisa tri can provide enhanced intermediate vision performance with its addition of +1.66 D, compared to apodized bifocal or convoluted trifocal IOLs, even under poor light conditions,” according to the release.
