Cataracts are part of the natural aging process. Everyone gets them to one degree or another if they live long enough. Cataracts, as they progress, create increasing difficulty with the normal activities of living. The symptoms vary from one person to another. Some people have more difficulty with their distance vision, some with reading. People may report difficulty with glare, or foggy, blurry, or hazy vision.

Doctors have noticed an increase in requests for second opinions because patients are sometimes told they have cataracts and they HAVE to have surgery--even though the patient has no visual complaints. Just having a cataract is not a reason to have cataract surgery.

According to the American Academy of Ophthalmology, "The decision to recommend cataract surgery should be based on consideration of the following factors: visual acuity, visual impairment, and potential for functional benefits." Therefore, the presence of a cataract is not enough to recommend surgery. There needs to be some degree of visual impairment that is altering the ability to perform your normal activities of daily living. There also needs to be some reasonable expectation that removing the cataract is going to improve vision.

A patients with advanced macular degeneration has significant visual impairment. If she has just a mild cataract, then removing that cataract is unlikely to alleviate the visual impairment. You therefore need to have both things - a visual impairment that interferes with your normal daily activities AND a reasonable expectation that removing a cataract is going to help improve vision to a significant degree.

There are some instances where a dense cataract might need to be removed even though the above criteria are not being met. One example is when a cataract gets so bad that it starts causing glaucoma. Another instance would be if the cataract interferes with treating a retinal problem because the retina cannot be well visualized if the cataract is severely hampering the view of the retina. Those conditions are VERY rare in the U.S.

Most people who need cataract surgery are aware they have a visual impairment and that impairment is altering their normal daily activities. There are times, however, when we recommend cataract surgery because there is a visual impairment but the patient is not aware of just how bad their vision is. For example, the legal driving requirement in New Jersey is 20/50 or better in at least one eye. So we do occasionally see a patient who think he sees fine but when tested his vision is worse than 20/50 and he is still driving. In that case we would recommend cataract surgery (assuming the cataract is the problem) even though the patient does not think he has an impairment.

If you have been told you need cataract surgery but feel you are not having any significant visual problem, you should consider getting a second opinion.

Ask Dr. Stewart Your Eye Care Questions

What can be expected during a contact lens fitting?

A patient can expect to have a different experience when having a contact lens fitting. In addition to the eyeglass exam, questions will be asked to determine which contact lens will work best for them. Will they want to leave the lenses in their eyes overnight or will they remove them every day? Will they wear them only occasionally or will they be for everyday use? Do they want a contact lens that they throw away every day or do they want a contact lens that they have to clean and disinfect? If the patient is over age 40 and has a compromised ability to see up close, how will they see up close with their contact lenses? Will they wear readers over their distant contacts, or will they wear multifocal contacts, or will they wear monovision?

Are some people more prone to having Dry Eyes than others?

Experiencing dry eye symptoms is more common as we grow older, particularly in people 50 years of age and older. Hormonal changes in women who are experiencing menopause or who are post-menopausal. Inflammation in our body can affect the tear gland's ability to produce tears. Eye or health conditions such as glaucoma, diabetes, lupus, rheumatoid arthritis, and Sjogren's Syndrome can be associated with Dry Eyes. Environmental conditions such as dry winter air, dry indoor heated air, working on the computer, and wearing contact lenses can cause Dry Eyes.

Are there advantages to single-use contact lenses? What are they?

Single-use daily wear contacts are convenient to the patient and a healthy recommendation from their eye doctor. At the end of the day, the patient only has to dispose of the contacts. There is no need to take the contacts out to clean and disinfect them. The patients time and money spent on solutions and caring for them are eliminated. Not to mention that the next time they wear a contact, they will be wearing a brand new contact! The single best recommendation your eye doctor can make is to recommend single-use daily wear contacts. They are the healthiest contact that can be worn. The contact lens pathology issues of wearing the same contact for two or four weeks such as neovascularization, microcystic edema, and bacterial infections are greatly reduced.

What is an eye infection?

Your eyes can get infections from bacteria, fungi, or viruses. Eye infections can occur in different parts of the eye and can affect just one eye or both. Two common eye infections are conjunctivitis (also known as pink eye) and lid styes which are swollen lid bumps that can also be painful. Common signs of an eye infection are pain, itching, or a sensation of a foreign body in the eye, photosensitivity, redness or small red lines in the white of the eye, discharge of yellow pus that may be crusty upon awaking, and tears.

What happens during a typical Diabetic Eye Exam?

Your Eye Doctor will evaluate the back of your eye called the Retina to check for leaking blood vessels. Diabetic retinopathy occurs when elevated blood sugars damage the walls of the blood vessels. The vessel walls may thicken, leak, develop clots, close off, or grow balloon-like defects called microaneurysms.

My eyes tear all the time. Why do you call it Dry Eyes?

Your eyes have extra tears because your eyes produce extra tears to combat irritation and dryness. A better way to describe Dry Eyes is tear film instability, which refers to the composition of your tears not being in the proper composition. Stopping eyes from producing extra tears is a goal in the treatment of Dry Eyes.

At what age should my child have his/her eyes examined?

If you ask 10 different Doctors you will get 10 different answers. Newborns have their eyes checked in the birthing ward for starters. From birth to age 5 their eyes are growing. At age 5 is a good time to schedule a regular eye examination, however, if any unusual eye behavior is observed under age 5 an eye exam should be scheduled at that time. Unusual eye behavior such as eye squinting, a head tilt, or having to get close to see.
