Advanced Lens – Customizing Your Visual Freedom
During traditional cataract surgery, your eye’s natural lens will be replaced with a synthetic monofocal intraocular lens (IOL). The surgery will bring a patients vision back to where it was prior to the onset of cataracts, however, if prior to cataracts he or she had a prescription for glasses or contact lenses, those visual aids will still be required for both distance and reading vision. Many patients are satisfied with this lens, as it restores their vision to a functional point.
Some patients seek to restore their vision to complete capacity with one surgical procedure, thus leaving glasses or contact lenses behind for life. Recent advancements in visual technology have produced ‘advanced lenses,’ which can be customized to work with your individual needs. Often referred to as ‘lifestyle lenses,’ this advanced technology affords patients many advantages over the traditional monofocal lens. Even patients suffering from astigmatism can potentially eliminate dependency on glasses, reading glasses and contact lenses. Imagine having no need for readers to see menus, computer screens, and labels!
At Williamson Eye Center, we work with each patient to develop a customized treatment plan to suit even the busiest lifestyle. It is our commitment to deliver the best results to leave you free of the hassle of glasses and contact lenses for life.
ADVANCED LENSES: A VARIETY OF TECHNOLOGIES
Tecnis Symfony IOL
For those suffering from presbyopia and cataracts, there is a new Intraocular Lens (IOL) on the market called the Tecnis Symfony. The Symfony is the first of its kind that’s able to treat both cataracts and presbyopia while improving a full range of vision. Unlike most intraocular lenses, the Symfony IOL exhibits a low instance of the effects of halos and glare around lights. Instead, patients are left with a clear, crisp vision. Even if a patient has cataracts, they get the full range of their vision back: intermediate, distant and near vision. The Symfony IOL allows for a higher quality of life and a lessened dependence on reading glasses.
The Symfony IOL is ideal for patients who are already candidates for receiving cataract surgery. During cataract surgery, the Symfony IOL is implanted in the eye. The Symfony IOL is used to replace the cataract-affected lens in the eye, leaving in its path clearer vision. The Symfony IOL doesn’t affect the way that cataract surgery is performed. Instead, it only changes the way that you see after. Most patients are able to see more clearly almost immediately after surgery, and full results are achieved thereafter.
The Tecnis lens is classified as a “multifocal” lens as it offers the patient multiple points of focus after surgery. As opposed to only correcting distance vision with the basic lens, the Tecnis lens design allows you to see well at distance, intermediate, and near…often with little need for glasses. You must be a good candidate to receive the multifocal lens and patients with large amounts of astigmatism, a history of prior cornea surgery (such as RK, LASIK, and PRK) as well as those with retina issues (macular degeneration, diabetic retinopathy, prior retinal surgery) are usually not good candidates for this lens. With few side effects, the new Tecnis lens design has greatly improved the occasional glare and halo effect seen with older generation multifocal lenses. This lens is the best option for patients who desire excellent near vision for reading without the use of reading glasses. It’s also an excellent choice for the “refractive lens exchange” procedure, which is performed on patients in their 40s and 50s who are unhappy with their inability to read close-up due to presbyopia.
Allowing a patient seamless focusing ability at all distances, the Crystalens IOL mimics the eye’s natural ability to accommodate for focusing on objects at varying distances. In the same way muscle movements accommodate viewing, the technology of the Crystalens can move between up close and far away and can be a great solution for patients who require improvement for reading and up-close vision.
The basic lens implant will not correct astigmatism so these patients will need a specialized lens, called a toric lens, to correct their astigmatism in order to have better vision without glasses. The Trulign lens is a toric lens that is designed to correct both cataracts and astigmatism. At the same time, however, the innovative design of this lens allows it to move within the eye when you are focusing at objects closer to you providing an overall broader “range” of vision compared to a typical toric lens. This often allows for a good distance and intermediate vision with less dependence on glasses. While patients usually still need light reading glasses for near vision and smaller print, they are able to do most things glasses-free which compliments their overall active lifestyle. This lens is an excellent choice for patients who have too much astigmatism or other eye problems which make them a poor candidate for multifocal lenses, yet they still would like a broader range of vision and an improved depth of focus than what is available with the basic lens.
For patients suffering from astigmatism, a Toric IOL lens was created to neutralize the imbalance of corneal asymmetry. Previously, patients with astigmatism in addition to cataracts still had to use glasses or contact lenses to reduce the effects of astigmatism. With a Toric IOL implant rather than a traditional monofocal lens, any imbalance created by astigmatism is reduced and even eliminated, allowing for crystal clear distance vision.
The Visian ICL is made of Collamer an advanced lens material that has unique properties. Collamer transmits light and reduces reflections that can interfere with vision, so you see clearly. Made of a copolymer and collagen, Collamer is also highly biocompatible. It allows the Visian ICL to rest quietly in position while accurately correcting vision. Collamer is the only lens material made with collagen- the best choice for a lens that is going to remain inside your body for a lifetime. The Visian ICL does not alter any structures within the eye. If necessary, it can be removed from the eye by a simple surgical procedure.
At Williamson Eye Center, we take great care in the selection of lifestyle lenses we provide to our patients. For a multifocal IOL, we utilize the Acrysof ReSTOR. This lens works much like a pair of bifocal glasses, allowing patients to see clearly at all distances. This lens incorporates a range of viewing areas, returning your vision to its broadest range. Many patients who choose the Acrysof ReSTOR, are never dependent on glasses again!
