Getting Ready for Cataract Surgery
Once you’ve decided to have cataract surgery,
your doctor will work with you to help choose the intraocular
lens, or IOL, that will be placed in your eye during the
procedure.
There are two basic types of IOLs, each designed to correct
vision at a specific visual range. Monofocal lenses only correct
vision at one portion of your visual range (typically vision at
a distance), while multifocal lenses are designed to correct a
full range of vision – near, far and everywhere in-between.
Your doctor will work with you to decide which IOL is best
suited for your unique visual needs. For instance, you may be a
candidate for the AcrySof® IQ ReSTOR® IOL, an advanced type of
multifocal IOL that can offer you the chance for complete
freedom from glasses. Ask your doctor if the AcrySof® IQ ReSTOR®
IOL is right for you. |

AcrySof® IQ ReSTOR® IOL
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! |

How does the AcrySof® IQ ReSTOR® IOL work?
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 older1,
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. |

Refractive Technology
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. |

Aspheric Technology
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. |

Clear Distance Vision without Glasses or
Contacts
For cataract patients with astigmatism, successful cataract
surgery is only half the battle toward regaining quality vision.
Until recently, the only viable vision correction options for
astigmatism correction after cataract surgery were eyeglasses or
contact lenses, both of which are not only inconvenient in terms
of lifestyle, but can also be expensive over a lifetime.
The advanced technology behind the AcrySof® IQ Toric Intraocular
Lens (IOL) offers a combined solution, not only replacing your
cataract-clouded natural lens for clear vision, but also
correcting corneal astigmatism, so you can see in focus.

Quality Distance Vision — Unhindered by
Cataracts and Astigmatism
The technology behind the AcrySof® IQ Toric IOL offers cataract
patients with preexisting astigmatism precise vision correction
that reduces or eliminates corneal astigmatism and delivers
significantly improved distance vision without the need for
glasses or contacts. You'll also be able to enjoy improved image
quality thanks to the lens' new aspheric design.
With the AcrySof® IQ Toric IOL, your distance vision can be
clear, vibrant and in focus, all with just one lens! |
