Cataract Surgery Lens Options
Voted Best of Berks—

Cataract lens replacement, also known as cataract surgery or intraocular lens (IOL) implantation, is a common and effective procedure to treat cataracts, a condition characterized by clouding of the natural lens of the eye. Cataracts can cause blurry vision, difficulty seeing at night, increased sensitivity to light, and overall reduced vision quality. Our Eye Consultants of Pennsylvania surgeons offer several cataract surgery lens options.
How cataracts form
Cataracts form when the natural lens of the eye becomes clouded due to the buildup of proteins which lead to decreased transparency. Aging is the primary factor contributing to cataract development. Additionally, prolonged exposure to ultraviolet (UV) light, smoking, diabetes, certain medications, and eye injuries may increase the risk of cataracts. As the cataract progresses, it obstructs light from reaching the retina, causing blurry vision, sensitivity to light, and difficulties in seeing clearly.
How cataracts are treated
The only effective treatment is cataract surgery to replace the clouded lens with an artificial intraocular lens to restore clear vision. Lens advances are amazing, and you have several lens options available. We choose these based on your individual needs, lifestyle, and preferences.
Monofocal lenses are the most common lens used. These lenses correct vision at one distance, either near or far. Most of our patients choose a lens for distance vision and opt to use reading glasses for close tasks.
Monovision surgery means that one eye is corrected for distance vision, while the other is corrected for near vision. This approach can reduce the need for reading glasses, but it may affect depth perception and some people may find it less comfortable.
Multifocal lenses are designed to provide clear vision at multiple distances. These lenses reduce the need for reading glasses or bifocals.
An accommodating lens mimics a natural lens by shifting focus between near and distance vision as your eye muscles move. These lenses are designed to provide a broader range of vision and reduce the need for glasses.
A toric lens is specifically used for patients with astigmatism. Our surgeons can correct both cataracts and astigmatism in the same surgery to provide improved distance vision without the need for glasses or contact lenses. In some cases, we may also recommend an aspheric lens, which is designed to provide better contrast sensitivity and reduce spherical aberrations to improve vision, especially in low-light conditions.
The choice of the cataract lens option should be made in consultation with your eye surgeon, who will consider your lifestyle, visual needs, and any existing eye conditions or astigmatism. Your surgeon will help you determine which option is best for you based on a comprehensive eye examination and a discussion of your goals and expectations. It’s important to have realistic expectations regarding your post-surgery vision and discuss any potential side effects or trade-offs associated with each lens type.
At Eye Consultants of Pennsylvania, we provide cataract surgery lens options and a cataract surgery experience tailored to your individual patient needs. As with any surgical procedure, there are risks involved, and it’s crucial to discuss the benefits and potential complications with our team so that you can make an informed decision about the treatment.
