An intraocular lens or IOL is an artificial lens used to replace a defective natural lens, like one with a cataract. A cataract is a condition in which the lens of the eye becomes cloudy. It is generally associated with the aging process; as someone gets older, proteins inside the lens start to break down and cause cloudiness. Most people start showing signs of cataracts when they are over 60 years old. Those signs include dulled or yellowed vision, blurry vision, trouble seeing at night, and abnormal sensitivity to light. Thankfully, you have lifestyle lens options after cataract surgery, including the TECNIS® Multifocal lens.
What Happens During Cataract Surgery?
Cataract surgery is quick and straightforward. At Live Oak Ophthalmology, we typically use a laser to help perform the surgery. The doctor will break up the lens and remove the pieces. He will then insert the IOL. In most cases, the eye will heal on its own, and the patient will not need stitches.
Types of IOLs
The oldest and most common type of IOL is the monofocal IOL, which is designed to focus at only one type of distance: near, medium, or far. Most patients get a monofocal IOL set for far, so they won’t need glasses for tasks like driving that require them to see things far away. They then use reading glasses when they need to see things up close.
A multifocal IOL, by contrast, enables the patient to focus on things that are both close and far away. The lens has “focal zones” that look like rings on the lens that enable the patient to focus at different distances. One clinical trial conducted in the US found that almost 90 percent of patients who got multifocal IOLs never had to wear glasses again.
A Closer Look at the TECNIS® Multifocal Lens
The TECNIS® Multifocal lens is a brand made by Abbot Medical Optics (AMO). It has been used in the US since 2009. The TECNIS® option has multiple “focal zones” that give the patient clear vision regardless of the light conditions.
Who is a Good Candidate for the TECNIS® Multifocal Lens?
The ideal candidate for the TECNIS® Multifocal lens will be someone in good health with realistic expectations. Patients who have no other eye problems are the best candidates and generally get the best results. Set up a time to visit our doctor at Live Oak Ophthalmology to learn more about your candidacy.
