Finally, the opportunity for freedom from reading glasses and bifocals.
Until recently, life without reading glasses or bifocals wasn't an option for most cataract patients. You now have that option. The AcrySof® IQ ReSTOR® IOL is a unique technological innovation that can provide you with enhanced image quality and a full range of vision – near, far and everywhere in-between – for increased independence from reading glasses or bifocals!
As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances – up close, far away and in-between. The ability to quickly change focus throughout our range of vision is called accommodation. Unfortunately, we begin to lose this ability as we grow older, gradually becoming more and more dependent on bifocals or reading glasses.
Thankfully, by combining the strengths of apodized diffractive and refractive technologies, the AcrySof® IQ ReSTOR® IOL can now provide quality near, intermediate and distance vision, and increased independence from reading glasses or bifocals. And now, with the addition of proven aspheric technology, the AcrySof® IQ ReSTOR® IOL takes the advancements one step further, for a lens with enhanced image quality and clarity.
Diffraction involves the spreading of light as it passes through a lens. You'll notice that, on the AcrySof® IQ ReSTOR® IOL, the center of the lens surface consists of a series of tiny rings – this is known as an apodized diffractive optic. Apodization is the gradual tapering of different diffractive levels (or "steps") on a lens, creating a smooth transition of light between distant, intermediate and near focal points. This means is that the series of tiny steps in the center of the AcrySof® IQ ReSTOR® IOL work together to focus light, providing excellent near, intermediate and distance vision.
Refraction involves the redirection of light as it passes through a lens. The outer ring of the AcrySof® IQ ReSTOR® IOL is a refractive region designed for excellent distance vision. This refractive area bends light as it passes through the lens, accurately focusing it on the retina for a crisp, clear image.
Even healthy eyes still contain some imperfections, or "aberrations." Spherical aberration, a type of imperfection common to cataract patients, can eventually lead to a reduction in visual acuity and function. Thankfully, with the addition of a proven aspheric optic, the AcrySof® IQ ReSTOR® IOL can correct for these spherical aberrations, leading to enhanced clarity.
Vision for your everyday life.
Incredible range of vision
For most patients, the AcrySof® IQ ReSTOR® IOL delivers excellent near, intermediate and distance vision, potentially without the need for reading glasses or bifocals. In fact, with this increase in vision quality, many AcrySof® IQ ReSTOR® IOL patients would be able to pass the visual acuity portion of the driver's license exam in most states.
The AcrySof® IQ ReSTOR® IOL delivers quality vision in a variety of lighting conditions. In brightly lit conditions, the central apodized diffractive portion of the AcrySof® IQ ReSTOR® IOL sends light waves simultaneously to near, distant and intermediate focal points; in dimly lit conditions, the surrounding refractive area sends more light for distance vision.
The AcrySof® IQ ReSTOR® IOL was designed with a unique aspheric optic that provides enhanced image quality compared to traditional spherical lenses. By correcting spherical aberrations that can develop on the lens with age, the AcrySof® IQ ReSTOR® IOL offers high-resolution image quality.
Finally, quality vision and true patient satisfaction.
Patients implanted with the AcrySof® IQ ReSTOR® IOL have experienced the lifestyle benefits that come with improved vision at all distances, and greater freedom from reading glasses and bifocals. According to the AcrySof® IQ ReSTOR® IOL clinical studies, three out of four patients implanted in both eyes with the AcrySof® IQ ReSTOR® multifocal IOL reported never wearing glasses following cataract surgery. Additionally, the AcrySof® IQ ReSTOR® IOL clinical studies indicate that over 95% of the study subjects were so satisfied with their new quality vision that they would have the AcrySof® IQ ReSTOR® IOL implanted again.
