A cataract is the clouding of the eye’s natural lens. To treat cataracts, surgeons remove the lens and replace it with an artificial lens, which restores clear vision. The specific type of artificial lens implant used is determined preoperatively, based on a discussion between surgeon and patient.
The standard type of IOL placed during surgery is the monofocal IOL, which is typically covered by Medicare insurance. This lens restores clear vision at a single fixed distance. Many patients with monofocal IOLs opt for the IOL to correct distance vision, and then they wear reading glasses to see clearly while performing up-close tasks like sending a text message or checking a watch.
The team at Berks Eye Physicians and Surgeons understands that although monofocal IOLs are certainly effective, they are not the ideal choice for every patient. We know that our patients are diverse and have unique vision needs; therefore, we offer several types of IOLs to suit different needs and goals.
Multifocal IOLs restore clear vision at multiple distances after cataract surgery. They can provide clear vision for near, intermediate and far distances, and are great for patients with active lifestyles. In some cases, multifocal IOLs eliminate the need to wear glasses altogether after cataract surgery.
Toric IOLs are designed to restore clear vision after cataract surgery and correct pre-existing astigmatism, a condition characterized by an abnormally curved cornea. There are a few versions of toric IOLs, including monofocal, multifocal and extended range of vision toric lenses.
Extended Range of Vision IOLs
The newest and most advanced IOL on the market is the Extended Range of Vision (a.k.a., Extended Depth of Focus) IOL, which provides a continuous full range of vision. Using technology called diffractive optics, the Extended Range of Vision IOL creates a single elongated focal point. This provides seamless, sharp vision at near, far and intermediate distances and every point in between. They are also well suited for patients with active lifestyles.
