Improving Lifestyle Vision with Small Aperture Optics
The Small Aperture Premium Lens Solution The IC-8 small aperture intraocular lens (IOL) is a revolutionary lens that extends depth of focus by combining small aperture technology with a monofocal lens. Clinical studies demonstrate that the IC-8 IOL produces unparalleled visual outcomes that deliver 1 : A continuous and uninterrupted range of vision Excellent image quality across the entire range of vision Good quality night vision with less symptoms like glare or halos A new standard in outcomes: Good near and intermediate vision without compromising far vision A highly forgiving lens when target refractive endpoints are missed Compensates to the effects of astigmatism up to 1.5 diopters of astigmatism Over the next few pages you will discover how this first of a kind small aperture IOL is revolutionizing the premium cataract clinic. You will see clinical and bench testing data that proves the IC-8 IOL is the lens that can help your patients achieve higher image quality and greater visual freedom. We invite you to learn more. one
Releasing the Power of the IC-8 IOL Delivering a Continuous and Uninterrupted Range of Vision Applying the same small-aperture principle optics as the KAMRA inlay, the IC-8 IOL incorporates a non-diffractive 3.23 mm diameter opaque mask with a 1.36 mm central aperture embedded within a 6.0 mm one-piece hydrophobic acrylic lens. The mask creates a pinhole effect, which delivers nearly 3.0 diopters of extended depth of focus by blocking unfocused peripheral light rays and isolating more focused central and paracentral rays through the central aperture2. The strength of the IC-8 IOL lies in its ability to extend depth of focus. As a result, the lens provides excellent image quality at all distances, and less trouble with glare and halos than lenses with two or three focal points. Before the IC-8 IOL: The natural lens is unable to focus light. Light Aberrations Lens cannot focus After the IC-8 IOL Implantation: The mask of the IC-8 IOL is able to focus light to provide a continuous range of vision. IC-8 Lens TM Well-established optical principles have shown that placing the IC-8 IOL in the non-dominant eye creates the same positive effect as bilateral implantation of two premium lenses. two
Providing Excellent Image Quality Near to Far As shown in the Air Force Target images on the opposite page, the IC-8 TM IOL delivers excellent image resolution across a broader range of vision compared to other premium lenses. Method for Measuring Optical Performance The standardized method of measuring IOL optical performance is with a technique called Through Focus. With this method, different IOL designs are optically bench tested under the exact same conditions. For Through Focus testing, optical image data is measured from +1.00 diopter to -2.50 diopters in 0.50 diopter increments to establish depth of focus. The best focus position is at 0.00 diopters or the plano position. A standardized Air Force image target is used to obtain test results. The image data presented on the next page clearly demonstrate the IC-8 IOL delivers excellent image resolution across a broader continuous Through Focus range of vision compared to other premium lenses. The testing conditions used for the optical test comparison test are described as follows: ISO Model Eye, ISO 11979-2, In Aqueous, Halogen White Light (440 755 nm) with a 3.0 mm aperture MTF data measured at 50 lp/mm Through Focus image data measured at 0.50 diopter increment steps Optical Metrology system use was highly accurate Effective Focal Length (EFL) method 97% of patients would choose the IC-8 small aperture lens again. three
IC-8 TM IOL: Targeting a refraction of -0.75 D does not result in a loss of distance visual acuity. +1.00 D +0.50 D +0.00 Plano -0.50 D -1.00 D -1.50 D -2.00 D -2.50 D Far Vision Near Vision Monofocal IOL: Air Force Targets demonstrate excellent image quality at best focus position (plano) but greatly reduced depth of focus, which results in poor image quality at intermediate and near distance. +1.00 D +0.50 D +0.00 Plano -0.50 D -1.00 D -1.50 D -2.00 D -2.50 D Far Vision Near Vision Diffractive Multifocal IOL: Air Force Targets demonstrate both a decrease in image contrast and ghosting. Ghosting is created by an in-focus image superimposed on top of an out-of-focus image as a result of splitting light to two foci. +1.00 D +0.50 D +0.00 Plano -0.50 D -1.00 D -1.50 D -2.00 D -2.50 D Far Vision Near Vision Trifocal IOL: Air Force Targets demonstrate both a decrease in image contrast and ghosting. Ghosting is created by an in-focus image superimposed on top of an out-of-focus image as a result of splitting light to three foci. +1.00 D +0.50 D +0.00 Plano -0.50 D -1.00 D -1.50 D -2.00 D -2.50 D Far Vision Near Vision Summary: The IC-8 IOL delivers excellent image resolution across a broader Through Focus range of vision with better image contrast and without ghosting symptoms as compared to other premium lenses. The IC-8 IOL also demonstrates a much greater depth of focus as compared to a standard monofocal lens. four
Raising the Standard in Outcomes Achieving Excellent Outcomes In a post-market clinical study conducted by AcuFocus, the average binocular visual acuities were 1.14 decimal (20/16-) at far, 0.91 decimal (20/20-) at intermediate and 0.71 decimal (20/25-) at near. By achieving the refractive targets of -0.75 D in the IC-8 TM eye and plano in the monofocal eye, visual outcomes can be further optimized. 1.25 Binocular UCVA (Mean, SD) Decimal Acuity 1.00 0.80 0.63 0.50 0.40 0.35 Near Intermediate Far 0.25 0.20 Mon 1 (n=105) Mon 3 (n=100) Mon 6 (n=90) Forgiving Presbyopia-Correcting Lens As the graph below demonstrates, the IC-8 IOL provides an excellent outcome even if the refractive target is missed.
