AcrySof SA60D1(+3); ReSTOR Apodized Diffractive IOL article

NEW TECHNOLOGY
ACRYSof IQ PanOptix

AcrySof IQ PanOptix 
Posterior Chamber Intraocular Lens (IOL) – TNF00

Advances in Artificial Lens Technology

There have been great advances in artificial lens technology. Examples of this include the AcrySof® PanOptix® lens and the AcrySof® IQ lens. Today, the AcrySof® family of lenses are among the most frequently implanted lenses in the world. This is largely due to the long-term clinical results of the lens. Furthermore, these lenses are made of a patented material developed specifically for the eye.

Family of Trifocal IOLs


Important Product Information

CAUTION: Restricted by law to sale by or on the order of a physician.

DESCRIPTION: The AcrySof® IQ PanOptix® Trifocal IOL is a type of multifocal IOL used to focus images clearly onto the back of your eye (retina) to allow clear vision after the cataract removal. In addition, the center of the AcrySof® IQ PanOptix® Trifocal IOL allows for better near (reading) vision and intermediate (computer work) vision versus what a monofocal lens would provide.

There is a chance that you still may need glasses for distance, intermediate, and/or near vision. You will get the full benefit of the AcrySof® IQ PanOptix® Trifocal IOL when it is placed in both eyes. Please discuss with your eye doctor whether this is the right IOL for you.

POTENTIAL SIDE EFFECTS: Due to the design of multifocal IOLs, there are some side effects that can be associated with the AcrySof® IQ PanOptix® Trifocal IOL models. These may be worse than with a monofocal IOL, including visual disturbances such as glare, rings around lights, starbursts (rays around light sources), and reduced contrast sensitivity (decrease in ability to distinguish objects from their background, especially in dim lighting). These side effects may make it more difficult to see while driving at night or completing tasks in low lighting conditions, such as at night or in fog or in a dimly lit room, after surgery as compared to before surgery.

Further, a toric IOL corrects astigmatism only when it is placed in the correct position in the eye. There is a possibility that the toric IOL could be placed incorrectly or could move within the eye. If the toric lens is not positioned correctly following surgery, the change in your astigmatism correction by the IOL, along with any necessary correction with glasses, may cause visual distortions. If the lens rotates in your eye, you may need additional surgery to reposition or replace the IOL.

ATTENTION: As with any surgical procedure, there are risks involved. Prior to surgery, ask your eye doctor to provide you with the Patient Information Brochure for the proposed AcrySof® IQ PanOptix® Trifocal IOL to be implanted. This document will further inform you of the risks and benefits associated with this IOL. Discuss any questions about possible risks and benefits with your eye doctor, as well as your medical condition and any eye disease you may have.

The ReSTOR IOL is a posterior chamber lens developed by Alcon Laboratories, Inc.

Finally, the opportunity for freedom from reading glasses and bifocals.

Until recently, life without reading glasses or bifocals was not an option for most Cataract:

A "clouding" of the lens in your eye. As light passes through the cataractous lens, it is diffused or scattered. The result is blurred or defocused vision.   Accommodation: The ability of the eye's lens to change shape to focus on objects at various distances. . Unfortunately, this ability diminishes as we grow older1, causing us to become dependent on bifocals or reading glasses. 

 

Diffractive

Diffraction: The spreading of light. Occurs when light passes through discontinuities (i.e. steps or edges). In an optical system, light can be diffracted to form multiple focal points or images.

 and refractive technologies. Similar technology has been used for years in microscopes and telescopes to improve image quality, and has now been patented for use in intraocular lenses by Alcon.

 

Apodized Diffractive
Apodization is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. On the AcrySof® ReSTOR® IOL, the center of the lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in that center area work together to focus light for near  through distance vision

 

Distance vision: Refers to focal points that are typically 7 feet or further from your eyes. Items that typically fall within the distance range of vision are billboards, street signs, and movie screens.

 

Refraction

Refraction: Redirection of light rays as they pass through the lens.

 involves the redirection of light passing through the lens, to focus on the retina

Retina: The transmitter located at the back of your eye that sends the images to your brain.

The refractive region of the AcrySof® PanOptix® IOL bends light as it passes through the lens to a focal point on the retina. This outer ring of the AcrySof® PanOptix® IOL surrounds the apodized diffractive region and is dedicated to focusing light for distance vision.

When is it used?
 The ACRYSOF PanOptix IOL is used in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased independence from glasses following cataract surgery.

               

 

What will it accomplish?
The ACRYSOF PanOptix IOL has been shown in a clinical study to provide good near, intermediate and distance vision with increased independence from glasses in patients who have undergone cataract surgery.

The AcrySof® PanOptix® lens.
Sight changing, life changing.

Introducing a breakthrough in vision surgery. Now there's a revolutionary new way to potentially leave your glasses behind – introducing the AcrySof® PanOptix® intraocular lens (IOL), a breakthrough in vision surgery. AcrySof® PanOptix® has been uniquely designed to improve vision at all distances – up close, far away and everything in-between – giving cataract patients their best chance ever to live free of glasses.

 Near vision: Refers to focal points that are typically 16 inches or closer to your eyes. This is also known as "reading vision." Items that typically fall within the near range of vision are books, newspapers, and medicine bottles.
