Long Island Cataracts
For many people, cataracts are a part of getting older. There is simply no way to avoid the inevitable changes in the eye’s structures that lead to the cloudiness and opacity of the natural lens. The talented team of ophthalmologist at TOC Eye® are adept at reversing the visual deterioration of cataracts. The goal is to restore clearer vision with the help of advanced artificial lenses.
Causes of Cataracts
Cataracts are a natural consequence of aging. Over time, proteins in the lens start to build up, gradually clouding the lens (think of a window that is frosty or fogged up). The lens is the portion of the eye responsible for focusing light on the retina, which sends the image to the brain through the optic nerve. When the lens develops a cloudy cataract, light is scattered and the lens cannot focus it properly.
In rare cases, babies are born with congenital cataracts. Also, cataracts can develop from trauma to the eye or as a result of taking certain medications (e.g., corticosteroids).
- Cataracts usually cause visual symptoms, including the following:
- Blurry or hazy vision
- Double vision
- Poor vision in bright light conditions
- Poor night vision
- Halos around lights
- Yellowish-tinged vision
- Frequent changes in eyeglass or contact lens prescription
Types of Cataracts
There are a few different types of cataracts that are identified based on where they are located. The lens is a layered structure, similar to an onion. The outer layer of the lens is called the capsule, the layer inside that is the cortex and the innermost layer is the nucleus. Any of these layers can develop cataracts. A nuclear cataract develops in the center of the lens. A cortical cataract develops in the middle layer, and a posterior capsular cataract develops in the back outer layer of the lens.
Cataracts are diagnosed by an ophthalmologist or optometrist during an eye exam. The doctor wants to ensure there is no evidence of another eye disease that could compromise vision. The patient’s health history, any medical conditions and visual symptoms are discussed.
The patient’s visual acuity is measured with an eye chart to determine how much the cataract has affected near and distant vision. The eyes are examined in-depth using light and magnification. An instrument called a slit lamp microscope is used to examine the structures in the front portion of the eyes (e.g.., cornea, iris and lens). Then, the eyes are dilated with drops so the doctor can look at the structures at the back of the eye (e.g., retina, optic nerve).
How Are Cataracts Treated?
Cataract treatment depends on how badly the clouded lenses impair vision. If cataracts do not affect vision or affect it only minimally, they typically do not need to be treated. However, if cataracts impair a person’s everyday life, they need to be surgically treated. Surgical treatment involves removing the cataractous lens and replacing it with an artificial lens. Cataract surgery is extremely safe and common.
Intraocular Lens Implant Options
One of the components of cataract surgery is replacing the cataract (clouded lens) with an intraocular lens implant. TOC Eye® cataract patients have a choice in their intraocular lens implant (IOL). There are several types of intraocular lens implants with unique designs and features to accommodate a variety of visual needs.
