Q: What are multifocal lens implants?
A: Multifocal lens implants are often used in cataract surgery to reduce the dependency upon glasses for both distance and near vision after the surgery is completed. As with other medical technology, not everyone will be a good candidate for this type of surgical implant. Patients with corneal scarring or significant astigmatism, as well as surgical candidates with eye diseases such as diabetic retinopathy, glaucoma and macular degeneration, may not receive the full benefit from these lenses. Your eye care professional can help determine if this lens implant option is right for you.
Q: My doctor says I have a cataract, but he wants to wait a while before removing it. Why?
A: A cataract usually starts very small and practically unnoticeable, but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle. You need to continue to visit your eye doctor regularly so the cataract's progress can be monitored. Some cataracts never really reach the stage where they should be removed. If cataracts are interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it's time to discuss surgery with your eye doctor.
Q: Can younger people get cataracts?
A: Yes, it's very rare but some people are born with cataracts, or acquire them early in life as a result of an injury or surgery. Some such cataracts don't affect vision, but the eye doctor may detect it during an eye exam. Occasionally a child does have a cataract that interferes with vision development and requires treatment.
Q: Do I have to wait until my cataracts are "ripe" before I can have them removed?
A: No! Waiting for cataracts to get "ripe" refers to an outdated surgical technique. Today, we recommend cataract removal when your quality of vision interferes with your quality of life. It is possible to have 20/20 vision, yet be so disabled by glare from headlights or sunlight, that cataract surgery may be the right treatment. We will monitor your cataract progression and help you decide the proper timing of cataract surgery.
Q: What is a cataract? How will I know when I have one? What can be done to fix it?
A: A cataract is a clouding of the crystalline lens. The crystalline lens sits behind the iris, or the colored part of the eye. Its function is to fine tune our focusing system by changing shape as we view objects at different distances. Our lens eventually loses its ability to change shape; this is when we require reading glasses or bifocals. In addition, the crystalline lens can become cloudy or yellow as a part of normal aging. This is also known as an age-related cataract. Normal, age-related cataracts are unavoidable and everyone will develop them at some point if they live long enough. The discoloration of the lens leads to an overall blur, a decrease in contrast sensitivity, and a worsening of glare, especially at nighttime. Because they tend to develop gradually, the symptoms are often unnoticed by the patient. A yearly eye exam will allow your optometrist the opportunity to identify the cataracts and advise on how to proceed. When you and your optometrist determine that your cataracts are affecting your vision and are advanced enough to require removal, you will meet with an ophthalmologist. Cataract surgery is a safe and effective out-patient procedure that will reverse any vision loss caused by the cataracts; and it is usually covered by your medical insurance.
Q: My child saw 20/20 at their school physical. That's perfect vision for back to school, right?
A: Maybe! 20/20 only tells us what size letter can be seen 20 feet away. People with significant farsightedness or eye muscle imbalances may see "20/20", but experience enough visual strain to make reading difficult. Eighty percent of learning is visual so include a thorough eye exam in your child's Back-to-School list.
Q: Why is my child having trouble reading and concentrating on schoolwork?
A: Your child may have an underlying refractive issue, such as farsightedness, nearsightedness or an astigmatism that maybe be causing blurred vision, making it hard for your child to concentrate and focus. There may also binocularity issues, which is how well the two eyes work together, or focusing issues that can affect a child's schoolwork. When working with your child, we will evaluate the visual system including binocular and accommodative systems to determine if his/her vision may be interfering with academic success.
Q: One of the greatest tasks of a school-aged child is learning to read and in older children, the amount of reading required. What should parents be on the lookout for concerning their child’s reading and potential vision problems?
A: We often discuss vision problems as they relate to sitting in a classroom, but what about the playground or vision acuity’s effect on socialization and play?
Q: Today it seems that many children are very quickly diagnosed as learning disabled or dyslexic. Does vision play a role?
A: In some cases a large undetected prescription (farsightedness or astigmatism) or an eye muscle imbalance (binocular vision problem) can make reading and learning a challenge. Once properly diagnosed and treated, reading and learning tasks can become much more comfortable, visually.
