Cataract surgery involves removal of a patient’s cataract and replacement of the removed lens with an intraocular lens implant (IOL). Corneal Associates offers a variety of premium IOLs. With so many IOL options available, patients may initially be overwhelmed by their options.
Here’s the simplest way to put it. You’ve already decided to have cataract surgery, and that includes a standard IOL that is covered by health insurance. The surgery will remove your cataract, and the lens will give you good distance vision. However, you will probably need glasses or bifocals to read or use a computer, and possibly to play tennis and do other things outdoors that require a range of focus. If you need more independence from spectacles, then you should consider premium IOLs. Lenses like Crystalens® and ReSTOR® will give patients greater range of focus. The only hindrance to choosing premium IOLs for most patients is cost, as premium IOLs are not covered by insurance. However, look at it this way: you’ll be using your premium lens every waking moment for the rest of your life. If an active lifestyle and/or independence from glasses is important to you, and it’s something you can afford, then premium IOLs are probably something you’ll want to have. Specific details about premium IOLs can be explained below.
Options for Premium IOLs
Alcon AcrySof IQ ReSTOR®
The ReSTOR® IOL is designed to help patients with cataracts and presbyopia lessen or eliminate their need for glasses following cataract surgery. The ReSTOR® IOL uses apodization, diffraction and refraction to create a full range of vision without the need for reading glasses or bifocals.
Clinical trials showed that 80% of test case patients needed no glasses after surgery. Furthermore, more than 94% of patients stated they were so satisfied with their results that they would implant the same lens if given the surgery again. Best of all, 94% of patients required neither reading glasses nor bifocals to read. If reading vision is a problem for you, investigate premium lens implants for your cataract surgery or refractive lens exchange procedure. Although ReSTOR® has a sterling record and study results, understand that other lens options may be better suited to your needs. The doctors and staff at Corneal Associates will be able to determine if this lens is a good option for you after a through eye examination.
Alcon Acrysof® IQ Toric Aspheric IOL
Patients with cataracts and cornea astigmatism may benefit from a toric IOL. This class of IOL corrects a cataract and astigmatism simultaneously, delivering precise astigmatic correction and quality distance vision without glasses for qualifying patients.
Many dislike the appearance of glasses and prefer some other type of vision correction. Toric contact lenses may be a good option; however, some find contacts uncomfortable and experience difficulty in adjusting to them.
There are several surgical options your surgeon may choose to treat astigmatism, such as LASIK laser vision correction, astigmatic keratotomy (AK), or limbal relaxing incisions (LRI). However, if you are planning to have surgery to remove a cataract, you now have an additional option… the Alcon Acrysof® IQ Toric implantable lens that makes it possible to treat the cataract and correct the corneal astigmatism at the same time. Your eye doctor will recommend the option that is best for you.
What are your options for correcting astigmatism?
If you depend upon eyeglasses, you may have experienced the inconvenience of not being able to find your glasses when you really need them. Eyeglasses are easily lost or damaged, expensive to replace, and inconvenient to clean and maintain. The more active you are, the more eyeglasses interfere with your lifestyle by complicating your participation in daily and recreational activities.
If freedom from eyeglasses for distance vision is important to you, you now have a better option. The unique design of the AcrySof® Toric lens provides significantly improved distance vision and may reduce the need for corrective lenses.
Bausch & Lomb Crystalens®
The Bausch & Lomb Crystalens® is a premium lens implant approved by the FDA for the visual correction of adults with cataracts, with or without presbyopia. The Crystalens® is modeled after the human eye to use the tiny interior muscles to flex and accommodate in order to focus on objects in the environment at all distances. The Crystalens® dynamically adjusts to your visual needs.
The Crystalens® accommodating intraocular lens is made with hinges on each side that are designed to allow the optic, or the part of the lens that you see through, to move back and forth as you constantly change focus on images around you. Crystalens® is a small lens enabling it to flex or bend as you focus your vision.
The first and only FDA-approved accommodating intraocular lens
The only lens that uses the natural focusing ability of the eye
The only lens that provides a single focal point throughout a continuous range of vision from far to near, and everything in between
Few patients with Crystalens® have experienced glare, halos and night vision problems. Crystalens® focuses only one image to the back of the eye, unlike a multifocal lens that projects multiple images that are not entirely in focus, requiring your brain to “adjust” to the differences. In addition, Crystalens® vision is sharp and crisp because 100% of the light rays are available and distributed – when you need it.
The effectiveness of the Crystalens® was proven in clinical trials:
While we expect our patients to wear glasses part time for refinement, the following shows what many patients were able to see with Crystalens®:
98.4% of patients implanted with Crystalens® in both eyes could pass a driver’s test without glasses.
100% could see intermediate (24″ to 30″) without glasses, the distance for most of life’s activities.
98.4% could see well enough to read the newspaper and the phone book without glasses.
Significantly more patients implanted with a Crystalens® (88.4%) could see better at all distances than patients implanted with a standard IOL (35.9%).
Long-term experience means a safe and effective procedure – some patients have continued excellent vision 7 years after implantation with the Crystalens®. More than 100,000 Crystalens® have been implanted worldwide.
The chief advantage of Monovision LASIK is the freedom it can provide from reading glasses. After six to eight weeks the brain makes the vision changes automatically, without any conscious effort or awareness. Monovision LASIK makes it possible for a person to repeatedly change the range of focus, without having to constantly remove or add corrective lenses.
It is surprising how many patients adapt readily and happily to this vision option, however Monovision LASIK is not for everyone. People who are entering mid-life and are interested in learning more about Monovision LASIK should discuss the matter with their Corneal Associates eye doctor prior to undergoing surgery.
