Intraocular Lens Options
Cataracts make the lens of the eye cloudy so light does not pass through as it should. In turn, this makes vision blurry. An intraocular lens replaces the cloudy lens during cataract surgery. This makes it so vision is clearer and the clouding is gone. When considering cataract surgery, it is important to understand your lens implant options, so you can choose a lens that best matches your lifestyle. At Arena Eye Surgeons, we will educate you on options that will match your desires and vision goals you wish to achieve after cataract surgery.
These lenses allow you to focus at one set distance, which can be customized to distance, intermediate or near. Usually, the focusing ability is set at a distance which means reading glasses or bifocals are usually necessary to give patients the best possible near vision. Our surgeons use standard monofocal lenses considered to be the most advanced in their category, designed for distance and improving image quality.
Toric lenses are indicated for patients that have astigmatism. These lenses can be effective at reducing, or eliminating astigmatism in patients, and can help reduce or eliminate the need for glasses at a set distance.
Multifocal lenses are made up of concentric circles, which vary to allow the eye to focus at different distances. The center of the lens provides distance power, with each surrounding ring being used to stabilize vision at intermediate and close range. It is important to understand the limitations of this technology, such as reading glasses may still be needed for small print, and you may experience glare or haloing at night time.
Extended Depth of Focus (EDOF) lenses, like the Tecnis Symfony, are designed to provide a continuous range of vision for distance, intermediate, and near. Like the family of multifocal lenses, EDOF lenses may still require some patients to use glasses for extremely small detail.
