Cataracts obscure the eye’s natural lens and limit your ability to see details. The lens, a light-sensitive membrane in your eye, works like the film in a camera. Just as a foggy camera lens makes everything dim, a cataract makes it hard for you to see clearly.
Cataracts can develop from normal aging, from an eye injury, from previous eye surgery or if you have taken certain medications. Cataracts may cause blurred vision, dulled vision, sensitivity to light and glare, and/or ghost images. If the cataract changes vision so much that it interferes with your daily life, the cataract may need to be removed. Surgery is the only way to remove a cataract. The alternative to surgery is to not have the cataract removed. If you do not have the surgery, your vision probably will not improve and may continue to get worse.
You are more likely to develop cataracts if you have any of these risk factors:
- Too much sunlight exposure
- High blood pressure
- Excessive alcohol consumption
Common Cataract Symptoms
- Clouded, blurred or dim vision
- Impaired night vision
- Sensitivity to light and glare
- Need brighter light for reading and other activities
- Seeing "halos" around lights
- Frequent changes in eyeglass or contact lens prescriptions
- Fading or yellowing of colors
- Double vision in a single eye
- Most cataracts are related to aging.
- Some babies are born with cataracts or develop them in childhood, often in both eyes. These cataracts may not affect vision. If they do, they may need to be removed.
- Cataracts are more likely to develop in people who have certain other health problems, such as diabetes. Also, cataracts are sometimes linked to steroid use.
- Cataracts can develop soon after an eye injury, or years later.
During a comprehensive eye exam, our ophthalmologists quickly and accurately determine your diagnosis. If needed, this is confirmed using one or more of the following tests or procedures:
Visual Acuity Tests - These tests help determine if your vision is impaired.
Slit Lamp Exams - By giving your doctor a magnified three dimensional (3-D) view of your eye, this diagnostic tool makes it easier to find tiny abnormalities.
Retinal Exams - While examining your retina, your doctor checks your lens for signs of cloudiness.
Cataract Extraction Surgery - Surgical removal of a clouded lens is considered the best, most successful treatment for this condition. Bascom Palmer is one of the few facilities using the femtosecond laser. Working through a small opening at the front of the eye, the surgeon gently breaks up and vacuums out the clouded lens with the laser. This lens is then replaced with an intraocular lens (IOL), a clear, artificial lens surgically implanted inside the eye to replace the natural lens. An IOL acts like the eye’s natural lens by focusing light that enters the eye through the cornea and pupil onto the retina. Similar to prescription glasses or contact lenses, the IOL is chosen to match the patient’s visual needs. If you have astigmatism, your surgeon may correct it with a Toric IOL or another procedure such as LASIK or a limbal relaxing incision (LRI) to reshape your cornea. Your doctor will guide you in choosing the intraocular lens that is right for you, depending on your condition and preferences.
Lens options include
Intraocular Lenses - Whether surgery is done to remove cataracts or to correct farsightedness, various replacement lenses are available. The standard IOL is a monofocal lens that corrects distance vision. With this lens, you see well from a distance, but need glasses to read.
Presbyopic Intraocular Lenses - Newly approved alternatives to standard monofocal lenses, these accommodating lenses focus for both distance and near vision. One of these lenses, the Crystalens, is a monofocal lens that moves forward inside your eye to change focus from distance to near. This gives good distance vision and usable intermediate distance vision for a computer screen. Most people can also read large type without glasses but some need reading glasses to read small type. If necessary, correcting astigmatism is done with the limbal relaxing incision procedure.
Single Vision Fixed-Focus IOLs - These lenses provide sharp vision at a distance or sharp near vision. Single vision lenses do not correct astigmatism – any remaining astigmatism may produce blurring at all distances without glasses.
Toric Single Vision Fixed-Focus IOLs - These fixed focus single-vision lenses help people with astigmatism see better for distance or for near vision than they would with a non-Toric single vision IOL. Although Toric lenses improve visual sharpness at a distance or near without glasses, they do not provide both near and distance vision simultaneously.
Multifocal IOLs - These lenses provide good vision in each eye for both near and distance. They also come in toric forms that can correct astigmatism. These lenses provide distance and intermediate and/or reading vision. The optical results are not always perfect and some patients are bothered by subnormal distance and/or reading vision. Other common side effects include halos around lights at night and reduced vision in bright or dim light.
