Premium IOLs for Cataract Replacement
Wolstan & Goldberg Eye Associates is pleased to offer the ReSTOR®, Symfony, Crystalens®, Tecnis®, and Acrysof® Toric IOL, as advanced alternatives to the standard IOL replacement for cataracts. Unlike traditional IOLs, these lenses can eliminate or significantly reduce the need for correction by glasses, particularly reading glasses, after cataract surgery.
It is normal for most people to develop presbyopia and cataracts in their later years. After about the age of 40, the natural lens of the eye becomes increasingly inflexible, gradually reducing the quality of near vision and making reading glasses a necessity. This change is referred to as presbyopia. As years pass, the natural lens may also become cloudy. This change is called a cataract. There are many types of cataracts and most people, by the age of 70, require the natural lens to be replaced with an artificial intraocular lens (IOL).
The traditional artificial lens is a monofocal intraocular lens (IOL) that achieves good distance vision for most patients. However, many patients desire vision correction for near and intermediate vision without having to wear bifocal or trifocal glasses. Wolstan & Goldberg Eye Associates can offer alternative solutions to this traditional approach: the ReSTOR® IOL, Tecnis®, Crystalens® IOL, the Acrysof® Toric IOL, Crystalens Trulign® Toric IOL, and the TECNIS® Symfony IOL. There is no one lens implant that is “right” for everyone. Our surgeons will help you decide which option will do the most toward getting you to your goal vision.
ReSTOR® Intraocular Lens (multifocal)
The AcrySof® ReSTOR® IOL offers our patients the opportunity for good vision at any distance, eliminating or reducing the need for glasses after cataract surgery. In fact, in a recent FDA clinical study, 94 percent of patients were very satisfied with being able to drive or read the newspaper without glasses or contacts.
The AcrySof ReSTOR® intraocular lens replaces the natural lens. Unlike a standard monofocal lens, which has a smooth surface, the ReSTOR® IOL has a unique patented gradual diffractive step surface on the optic, which is called apodization. This apodized diffractive design gives the lens the ability to focus light correctly on the retina for images at various distances without mechanical movement of the lens. The apodized diffractive optics improves image quality while minimizing visual disturbances. The net result is an increased range of quality vision that delivers a high level of freedom from glasses, regardless of the lighting situation. Qualified surgeons providing the ReSTOR® lens must pass a rigorous certification process assessing their surgical skill, accuracy, and proficiency. All of our surgeons at Wolstan & Goldberg Eye Associates are part of a small group that has satisfied these requirements.
Tecnis® Intraocular Lens (multifocal)
The Tecnis® IOL is another exciting option for the treatment of both cataracts and presbyopia. This new implant, approved by the FDA in 2009, uses diffractive rings on its posterior surface to maximize clear images at all ranges of vision. It also has an aspheric optic design engineered to reduce the spherical aberration of an average cornea. The unique difference of the Tecnis® IOL is the diffractive rings run very close to the optic’s center and then continue out toward the periphery through the entire lens. As a result the multifocal effect of the lens is more independent of the pupil size.
Crystalens® Intraocular Lens (accommodating)
Our practice also offers the Crystalens® IOL, the first cataract replacement to use the muscles separated from the natural lens when the cataractous lens is removed from the eye. This provides the closest thing to natural focusing achieved to date.
The eye’s natural lens is attached to muscles that contract it to focus on intermediate and near objects. During lens replacement surgery, these muscles are detached from the lens and cannot be attached to an artificial lens. The traditional IOL used for cataract replacement is designed to provide good distance vision; middle and near vision is achieved through bifocal or trifocal glasses.
The Crystalens® IOL is the first cataract replacement designed to use the eye muscles for focusing. Special hinges attached to the top and bottom edges are activated by the muscles to provide focus by moving the lens forward and backward. This breakthrough takes advantage of the fact that, even though they are no longer attached to a lens, the eye muscles continue their natural focusing movements. Qualified surgeons using the Crystalens® must pass a rigorous certification process assessing their surgical skill, accuracy and proficiency. Our surgeons have satisfied these requirements.
AcrySof® Toric IOL (for astigmatism)
In order to see a clear image, light rays must pass through a perfectly round cornea to sharply focus in one spot on your retina.
However, some people are born with a condition called astigmatism. This means that the cornea is oblong rather than round, shaped more like a football than a basketball, and causes the light to focus on the retina in a line instead of a point.
Astigmatism may distort vision to appear like the right side of the illustration below. To achieve clear vision like the left side of the illustration, glasses or contacts are necessary.
In the past, patients with astigmatism who had traditional cataract surgery would still experience blurred distance vision. They would still need glasses or contact lenses because the lens replacement could not change their astigmatism. Recently, the FDA approved a monofocal IOL called the Acrysof® Toric IOL that can now correct both the cataract and astigmatism simultaneously. The unique design of the AcrySof® Toric IOL makes it possible for the eye surgeons to provide QUALITY distance vision for patients with astigmatism, independent of eyeglasses and contact lenses.
Crystalens Trulign® Toric IOL (accommodative lens with astigmatism correction)
Trulign lens can correct for both astigmatism and at the same time provide a broader range of vision for activities such as working on a computer or seeing instruments on your car. The TRULIGN Toric lens is designed for seniors with active lifestyles. Unlike a standard cataract replacement lens, the TRULIGN Toric lens allows the eye to focus and maintain clarity over a broad range of vision, while correcting for the patient’s astigmatism. The lens also delivers superior clarity of vision, even in low-light or nighttime conditions.
TECNIS® Symfony IOL (multifocal lens with astigmatism correction)
Wolstan & Goldberg Eye Associates is very excited to be one of the first practices in the South Bay to offer the Tecnis Symfony lens implant. It is currently the only lens available that can simultaneously correct both presbyopia and astigmatism, giving patients higher quality vision for both distance and up-close reading. The Tecnis Symfony IOL was designed to provide excellent vision at every distance – so there is no worry of trading one for the other.
