Premium Lens Implants

Font Re-Sizer

After cataract surgery, you can live a life without the hassles of glasses and contact lenses. If you have been suffering from cataracts or poor vision and cataract surgery is an option, you should be aware of a new technology that can help you reduce dependence on glasses and contacts after cataract surgery.

The patients of Westlake Eye Specialists now have the option to see at far, near and even intermediate distances after cataract surgery. This enables our cataract patients to be able to read the newspaper, play golf and other activities without the hassles of glasses.

Until recently, cataract patients had few choices for the implants used to restore their vision. With the premium lens procedure, you now have several choices based on your individual visual needs and lifestyle. In order to prepare for your premium IOL evaluation and consultation process, we suggest you think about the following items and also take our Premium IOL Self-Evaluation Test.

What are Intraocular Lenses (IOLs)?

Intraocular lenses, commonly referred to as IOLs, are implantable lenses used to replace the eye’s natural crystalline lens during cataract surgery. An IOL will assume the function of the natural lens and will be undetectable. Today, IOLs are available as monofocal lenses (correcting vision for one distance), accommodating lenses (correcting for near, far, and intermediate vision), toric lenses (astigmatism correcting), and multifocal lenses (correcting for near, far, and intermediate vision).

Lifestyle Items to Reflect Upon Prior to Choosing an IOL:

  • What are your hobbies?
  • Do you read for multiple hours a day?
  • Do you work and what is your occupation?
  • Do you drive a lot at night?
  • Do you use computers frequently?
  • What are your favorite outdoor activities?

Monofocal IOL

If you are a patient and have cataracts in both eyes, Monofocol Intraocular lenses may provide the best result. A Monofocol IOL is used to provide the patient with a fixed focus for one distance. Our doctors here at Westlake Eye Specialist will work with you to decide what distance would be appropriate for you whether that be near focus, mid-distance focus, or distant focus. With a Monofocol IOL, you are only able to choose one distance and the focus will not change after surgery. Traditional cataract surgery using a Monofocol IOL would give the patient focus for both eyes for distance and the patient would then use reading glasses to see near objects.

The majority of the patients we see here at Westlake Eye Specialists who choose to have Monofocol IOLs in both eyes choose the distance and then use reading glasses to see objects near.

Toric IOL

Toric IOLFor Cataract patients who have astigmatism, and who do not wish to wear eyeglasses to see clearly at a distance, choosing a Toric Lens Implant can help them be free of glasses for tasks such as driving, that require clear distance vision. Toric IOL technology uses biocompatible materials that have been successfully used in contact lenses and proven safe for the eye.
Astigmatism occurs when the cornea is more oval or football shaped instead of being a perfect sphere. The resulting vision is often blurry and distorted. Mild forms of astigmatism may not need correction, but the stronger the prescription gets, the more patients become dependent on glasses to see.

Toric Lens Implants do not correct Presbyopia, and therefore even with Toric Lens Implants to correct astigmatism after Cataract Surgery, most patients still require reading glasses or bifocals to be able to comfortably perform near vision tasks such as reading and intermediate vision tasks such as computer work.

Multi-Focal IOL

ReSTORA Multifocal Lens Implant is a lens that has a different power in the center of the lens and another power in the border of the lens so that vision can be focused for far or near out of the same eye. These different zones of lens power work together to provide the eye with near and distance vision. The lenses are made of plastic or silicone materials and placed permanently in the eye after removal of the eye’s natural lens. Subsequently, a Multifocal Lens can help correct Nearsightedness, Farsightedness, and Presbyopia.

The AcrySof IQ ReSTOR IOL is implanted during cataract surgery to replace the natural lens, which has become clouded by cataracts. This new lens can provide enhanced vision quality and a full range of vision, giving patients an increased independence from reading glasses and bifocals.

Our eyes are continuously focusing on objects at different distances. Whether it be watching television, sitting at a computer or driving, our eyes automatically focus on different things at different distances quite quickly. As we age, the ability for our eyes to change focus (or accommodate) weakens, which leads to the need for bifocals and reading glasses. By combining the strengths of apodized diffractive and refractive technologies, the Acrysof IQ ReStor IOL provides quality near, intermediate and distance vision and increased independence for reading glasses and bifocals.

The Lens Designed for Everyday Life

Compare the following images. Image A demonstrates what you might see with a traditional implantable lens. Although distance vision is clear, notice how the phone screen, hand and near objects are very blurry.

Now compare that with Image B with TECNIS Symfony® IOL. TECNIS Symfony® IOL provides high-quality continuous vision at any distance.

TECNIS Symfony® IOL is the first lens of its kind to combine two unique technologies for outstanding visual performance: an Extended Depth of Focus IOL provides a continuous range of high-quality vision from near to far and points in between and may reduce the frequency of wearing glasses.

Symfony TORIC IOL

Full Range Of Continuous Vision With Astigmatism Correction

Astigmatism is a condition; in which both distant and near objects appear blurred. The cornea and lens of the eye are ideally spherical. When one or both is curved more steeply in one meridian than another, the optics take on a toric shape, somewhat like an American football. This uneven curvature prevents light rays from focusing to a single point on the retina, blurring the visual image somewhat like a funhouse mirror. Astigmatism often occurs in combination with myopia (nearsightedness) and hyperopia (farsightedness).

Tecnis Toric IOL
The Tecnis Symfony Toric intraocular lens compensates for corneal astigmatism as well as a range of continuous vision including distance and near. It has two meridians of different power, which can be aligned with the steep and flat meridians of the cornea. While no guarantee can be made as to the final result, there is a better chance you will be able to see clearly in the distance and near without glasses if a Symfony Toric lens is implanted.

The Tecnis Toric intraocular lens compensates for corneal astigmatism. This lens does not allow for continuous vision including near but can provide exceptional distance vision. It has two meridians of different power, which can be aligned with the steep and flat meridians of the cornea. While no guarantee can be made as to the final result, there is a better chance you will be able to see clearly in the distance without glasses if a toric lens is implanted.

Tecnis Aspheric IOL

Standard monofocal lens implants have a single point of focus. When a standard lens is implanted, the patient usually chooses before surgery where to have their eye focused after surgery. Most patients choose distance vision, and they wear reading glasses after surgery. Some patients choose to be nearsighted; they wear distance glasses after surgery.  While no guarantee can be made as to the final result, there is a good chance you will be able to see clearly in the distance without glasses providing you don’t have astigmatism.

 

AcrySof® ReSTOR® Intraocular Lens

The AcrySof® ReSTOR® intraocular lens (IOL) is an artificial lens that can restore a patient’s full range of vision while reducing a patient’s dependence on bifocals or prescription reading glasses. This design utilizes technology which manages light delivered to the cornea by distributing light to distant and nearby focal points. This results in excellent visual acuity of nearby as well as faraway objects, allowing patients to read the print on medicine bottles, newspapers, and magazines while also providing vision of distant objects.
