First in Minnesota! The Apthera Lens for cataract surgery at Chu Vision Institute

Back to Blog

Dr. Chu and his surgical team are thrilled to offer this one-of-a-kind cataract lens technology: the Apthera IOL. This lens uses aperture technology to focus light in the eye so patients can see clearly close as well as far. It is different than some other lenses, like multifocal lenses which have rings for different focal points, similar to glasses that are bifocal or trifocal (each section focuses light at a different distance. The Apthera has a dark circle like a pinhole to help focus light smoothly through the different distances.

This lens is best for patients who tolerate monovision in which one eye is focused for distance and the other is focused for near. Watch the video below to hear about Wendy’s journey and learn more about the lens.
