In the past, cataract surgery could only correct vision at one distance, typically for driving, and watching television; but people would still need reading glasses after surgery. Now, people can get a multifocal intraocular lens (IOL) to correct vision at both distance and near.
If you are considering cataract surgery and want freedom from glasses after surgery, you should consider multifocal IOLs. These implants are designed to provide more range of vision than can be obtained by traditional cataract surgery. Most patients who choose multifocal IOLs are completely independent from glasses or use them only occasionally after surgery. There are currently two multifocal IOLs available, ReSTOR and Tecnis.
Feinerman Vision Center offers all of the premium IOLs (multifocal and accommodating IOLs). We do not use one company’s lens implant because not every person is best suited for the same type of lens. Dr Feinerman examines the individual person and looks at all of their measurements in order to choose the lens best suited for that specific individual.
AcrySof IQ ReSTOR
The AcrySof ReSTOR was FDA approved in 2005. It has an aspheric optic to reduce halos around lights at night. It improves vision at all distances by using a patented “apodized diffractive” design that optimally distributes light to distance, intermediate, and near focal points. This is dependent on the amount of ambient light available.
For example, at nighttime the pupil dilates and more light is distributed to the portions of the IOL that provide distance vision. This generally improves the driver’s view of the road at night. When reading with a good light source, your pupil constricts and more light is distributed to the portions of the IOL that provide excellent near vision.
Consequently, the ReSTOR IOL is light dependent, which means it will give good distance vision in dim light; but will require a good light source in order to provide clear reading vision.
The Tecnis Multifocal intraocular lens (IOL) is produced by Abbott Laboratories. It was FDA approved in 2009. The fully diffractive surface of the Tecnis Multifocal IOL provides excellent image quality at all distances under any lighting condition, and regardless of pupil size. It also has an aspheric optic to reduce halos around lights at night. According to Abbott, nearly 90% of patients are glasses free after surgery.
This state-of-the-art lens can provide cataract patients with the most comprehensive range of vision they can achieve with a multifocal IOL. As discussed earlier, traditional monofocal IOLs allow only one type of vision, usually distance, to be seen clearly. However, Tecnis is designed to provide a sharper focus of light, enabling its wearer to see more clearly at both near and far distances.
The Tecnis IOL’s unique design provides patients with an advantage by allowing them to see more clearly in low light as well as in bright light conditions. Whether near or far, day or night, Tecnis can give you back the visual range and independence you need to experience life to its fullest.
