Choosing the IOL that Best Fits Your Lifestyle
IOLs are soft, foldable lenses that are inserted into the eye in order to replace the natural lens that developed the cataract. Made of plastic or silicone materials, IOLs come with monofocal, multifocal, or astigmatism (toric) optics. Monofocal IOLs and High Definition IOLs provide a single zone of clear focus and are usually implanted to provide excellent distance vision. Toric IOL’s correct astigmatism for distance and near vision.
Patients with monofocal IOLs will typically require the use of reading glasses for near vision tasks, such as reading or sewing. Multifocal (Advanced IOLs) are designed to provide a full range of vision with minimal, if any, need for glasses or contact lenses.
The lens that is right for you will depend on your ocular health, your occupational needs and your lifestyle. It is important that you consider your options thoroughly as you only have cataract surgery one time in your life and the decision you make will affect how you see for the rest of your life.
Night Vision and Dim Light
For many patients, the most noticeable symptoms their cataracts produce are poor night vision, particularly glare; and/or a greater reliance on bright light to read. High Definition IOLs are better than others for improved night vision and low contrast or dim light situations.
Correcting Astigmatism with Toric IOLs
Astigmatism is typically caused by the cornea (clear window of the eye) being shaped more like a football than a basketball. This causes images to focus at different points on the retina, resulting in blurry or double vision. Astigmatism can also be caused by similar irregularities in the shape of the natural lens inside the eye.
For patients with pre-existing astigmatism, there are a number of Toric IOLs available. These include Toric Monofocal IOLs and Toric Multifocal IOLs. Without correcting your astigmatism, glasses will be necessary for all distances. Your doctor at Spindel Eye Associates will discuss the best method of correcting your astigmatism prior to your surgical procedure.
Presbyopia is a condition most people over the age of 40 experience that results in difficulty seeing up close without the aid of bifocals, trifocals, or reading glasses. This age-related condition is believed to be caused by a hardening of the natural lens inside the eye, making it difficult for the eye’s muscles to change its focus. Many people realize they have developed presbyopia when they find themselves having to push reading materials further and further away to focus.
Patients, who undergo cataract surgery with a standard monofocal IOL, will experience the same visual effects as presbyopia because standard monofcal IOLs can only focus at one distance. However, by choosing a presbyopia-correcting IOL, patients will realize a decreased dependence on glasses, contacts, or bifocals at all distances for most of their daily activities. Many people describe their vision with this option as being able to “see young again”.
There are a number of advanced presbyopia-correcting IOLs that we make available to our patients. Which one is best for you will depend on the unique characteristics of your eye, as well as your lifestyle needs.
