Enhancing Vision From Near to Far
A small central aperture filters unfocused light to extend depth of focus across multiple distances.1
Precision Technology for Extended Depth of Focus
At the center of IC-8® Apthera™ is a small-aperture optic designed to filter defocused light and extend visual range from near to far.1
Wavefront-filtering technology directs higher-quality light to the retina while preserving a familiar monofocal platform.1
Central Aperture Design
The IC-8® Apthera™ IOL uses a 1.36 mm central aperture to filter peripheral defocused light and extend depth of focus.1
- Precise Light Control: The Apthera™ IOL wavefront-filtering technology focuses only higher-quality light to the retina while filtering out unfocused, low-quality light.
- Small Aperture Technology: Continuously extended depth of focus for a seamless range of vision near to far.
The 1.36 mm central aperture directs higher-quality central light to the retina while filtering unfocused peripheral light.1
IC-8® Apthera™ incorporates a 3.23 mm Carbon Black FilterRing™ with a 1.36 mm central aperture.1
Carbon Black FilterRing™
- Hydrophobic Acrylic Platform: Trusted in cataract surgery for its biocompatibility and clarity.
- UV-Blocking and Glare Reduction: Carbon Black FilterRing™ incorporates recognized standards for patient ocular safety.
Built on a Trusted Monofocal Platform
- Surgical Familiarity: The IC-8® Apthera™ IOL uses a high-quality monofocal platform, so surgeons can expect the handling and implantation ease they already know while addressing presbyopia.
- Reliable Materials: Hydrophobic acrylic and UV-blocking construction offer durability and safety.
IC-8® Apthera™ is built on a high-quality aspheric monofocal platform that supports its small-aperture optical design.1
Monofocal-like Distance Vision
A monocular small-aperture strategy designed to support binocular distance, intermediate, and near vision.1
Vision for Everyday Activities
The IC-8® Apthera™ IOL is implanted monocularly, with your preferred monofocal or monofocal toric IOL in the other eye.
With a small amount of near correction (-0.75 D) in the IC-8® Apthera™ IOL eye and emmetropia in the fellow eye, patients can achieve monofocal-like distance vision, while providing enhanced visual acuity through intermediate and near for everyday activities.
Additionally, this intentional combination delivers binocular monofocal-like contrast sensitivity in bright and low light conditions.
See Across a Full Range of Vision, Without Blur
With approximately -0.75 D of near correction in the IC-8® Apthera™ eye and emmetropia in the fellow eye, the intended binocular strategy supports monofocal-like distance vision with enhanced intermediate and near visual acuity.1
This binocular approach is designed to provide monofocal-like contrast sensitivity in bright and low-light conditions.1
IC-8® Apthera® is designed to support a continuous visual range from near to far through small-aperture wavefront filtering.1
With the addition of a small amount of myopia, the Apthera™ IOL improves intermediate and near vision without significantly compromising distance vision1.
When implanted contralaterally with a monofocal IOL in the fellow eye, Apthera™ IOL patients maintain better than 20/32 across 2.21 D of binocular distance-corrected depth of focus1
