The major health benefit is they contain a transparent UV coating which blocks out the invisible ultraviolet rays of the sun. Ultraviolet rays are what cause sunburn, and so are present even on overcast days. Because of the potential for cumulative damage to the retina over time, you should block out ultraviolet light. All modern IOL’s are permanently coated in order to provide this UV protection at all times. Since IOLs haven’t any dark tinting, patients may still choose to wear sunglasses for comfort, just as they did before their cataract surgery. The following discussion applies to healthy eyes with no other ocular diseases, problems, or history of surgery.
- There have been no complications due to the material itself.
- Due to variability in biological systems , there may be inaccuracies in the formulas.
- If these risk factors sound familiar, you might develop cataracts at an earlier age.
This second step of refinement puts our surgeons in an elite band of cataract surgeons and is crucial when you are considering a multifocal lens implant. For multifocal lenses are patients with healthy eyes, motivation to be less dependent on eyeglasses or contacts, and willingness to adapt to minor visual effects from the lens. Because no current technology is ideal there may be circumstances where glasses must achieve comfortable vision. An eye doctor may decide on a monofocal lens for near focus, mid-distance focus, or long-distance focus, but only one may be selected.
The Symfony lens merges two technologies to achieve these goals. The first is the proprietary echelette design, which elongates the focus of the attention, in order to give the extended vision. A monofocal lens has one distinct center point at distance or near, while a multifocal lens has two distinct foci at distance and near. The Symfony lens has one elongated center point to allow distance, mid-range, plus some near. Since this design is proprietary, the maker will not go into more detail as to how this elongated center point is achieved. As long as you don’t have astigmatism, a monofocal lens can be used to correct a single selection of vision.
- About OCL Vision We deliver first-class eye treatments across London, Herts and Kent.
- For many people, the mind adapts and can synthesize the info from both eyes to supply adequate vision at all distances.
- If someone is interested in learning more about their premium lens options then the discussion moves forward.
It takes two to a month for a problem of this nature to develop. There is an additional out-of-pocket charge for the Symfony lens because Medicare and medical health insurance plans cover only the original replacement lens. The new lens extends the depth of focus, improves contrast and enhances the overall visual experience, in accordance with Dr. Haber.

•Before surgery your eyes are measured to find out your IOL prescription, and you also and your Eye M.D. Will compare options to decide which IOL type is best for you, depending partly on how you are feeling about wearing glasses for reading and near vision. Toric — similar to the single vision lens, but corrects for astigmatism. This allows patients with astigmatism to see well in the distance OR near, and then wear glasses for another one. Insurance, Medicare, and secondary insurances do not cover this lens, so there is an out-of-pocket expense. Monovision – distance vision in one eye and reading vision in the other eye.
For instance, in case you are nearsighted, have troubles seeing some type of computer, or are farsighted, a monofocal lens can be used to treat one of these problems. To help correct the remaining issues, glasses or contact lenses can be used. As an extra benefit of monofocal lenses, they don’t have any glare or halos at night— leaving you feeling well informed while driving in the dark.
There are many different forms of lens implants each with different advantages and disadvantages. Generally, these implants function similarly to a lens and help focus images in the eye. During cataract surgery, a cataract surgeon removes the cataract, that is the eye’s natural lens that has become cloudy and yellow. The capsule that was holding the cataract is left set up inside the eye. So that you can replace the optical focusing power of the lens , the cataract surgeon places an artificial acrylic intraocular lens implant within the capsule in order that the eye can see again. Your cataract surgeon can choose a lens to target a certain refraction after surgery, and perhaps you may not need glasses at all.
Cataract surgery is the same no matter which IOL you select, but surgeons can use one of two approaches. To look for the best treatment for you, please complete our simple form to schedule a consultation exam. These issues can make driving at night difficult, as the lights from ongoing cars can leave this type of big impact that it could be hard to see other items. According to the American Academy of Ophthalmology , most lenses are created from silicone or acrylic.
