The IOL you choose matters.Traditional IOLs are monofocal. This means that they are only able to focus clearly at one visual point. If you choose a monofocal IOL, you may see clearly at distance, but still require glasses for near vision tasks after cataract surgery. Also, Traditional IOLs do not correct for astigmatism, which occurs if there is an irregular curvature of the cornea (the clear front cover of the eye over the lens, the iris and the pupil), causing vision problems. In other words, your nearsightedness can be corrected, but you may see blurry and still require glasses to focus your vision for both distance and near and vision tasks after cataract surgery. However, recent advances in IOL technology have resulted in a wide range of High Tech IOL options. Many High Tech IOLs are multifocal and provide you with the ability to focus clearly at multiple distances. In many instances, the use of a High Tech IOLs will reduce, if not eliminate entirely, your need for glasses after cataract surgery. Astigmatism can also be treated with laser assistance during cataract surgery. Other benefits of using High Tech (multifocal) IOLs include:
Better range of vision
Improved vision in a wide range of lighting conditions
Improved ability to read and perform other near vision tasks
Dr. Edwin M. Schottenstein offers several High Tech IOL options in addition to traditional monofocal IOLs. These include:
Toric IOLs — Toric IOLs are an excellent option if you have astigmatism, a condition that occurs as a result of having a cornea that is oval-shaped instead of round. Prior to the development of toric IOLs, patients with astigmatism always needed glasses after cataract surgery. By choosing a toric IOL, you may be able to eliminate your dependence on distance glasses after surgery, but you still will require glasses for near vision tasks.
Multifocal IOLs — Multifocal IOLs allow you to focus clearly at multiple distances. Not only will these IOLs be able to potentially eliminate the need for glasses after cataract surgery, but they are also an excellent option to combat the near vision issues associated with presbyopia.
Toric Multifocal IOLs — Toric multifocal IOLs are one of the newest and most advanced options available. They provide clear focus at all distances while allowing you to simultaneously correct for astigmatism.
It’s important to understand that High Tech IOLs are more expensive than traditional monofocal IOLs. Therefore, you’ll need to weigh the increased cost against the convenience benefits you’ll experience by reducing or eliminating your dependence on glasses. Dr. Edwin M.
