FAQS

1. How Is Keratoconus Treated?

Treatment usually starts with new eyeglasses. If eyeglasses don't provide adequate vision, then contact lenses may be recommended. With mild cases, new eyeglasses can usually make vision clear again. Eventually, though, it will probably be necessary to use contact lenses or seek other treatments to strengthen the cornea and improve vision.
A last resort is a cornea transplant. This involves removing the center of the cornea and replacing it with a donor cornea that is stitched into place.

2. What are the age requirements for LASIK?

Millions of people are choosing to undergo LASIK laser surgery because of its overall safety and effectiveness in improving vision. Although ideal candidates are at least 18 to 21 years old, many parents wonder if it would be similarly effective on their children. Likewise, many people over the age of 40 are curious as to whether they will remain suitable candidates for as they continue to age. When considering if LASIK is right for you, it is important to remember that every generation faces its own unique needs and issues when it comes to vision. A qualified refractive eye surgeon in your area can answer any questions you may have regarding age and LASIK eye surgery.

3. What Are the Advantages of LASIK Eye Surgery?

• It works! It corrects vision. Around 96% of patients will have their desired vision after LASIK. An enhancement can further increase this number.

• LASIK is associated with very little pain due to the numbing drops that are used.

• Vision is corrected nearly immediately or by the day after LASIK.

• No bandages or stitches are required after LASIK.

• Adjustments can be made years after LASIK to further correct vision if vision changes while you age.

• After having LASIK, most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.

4. Will sitting too close to the television set hurt my child's eyes?

No, there is no scientific evidence that TV sets emit rays that are harmful to the eyes.

5. Do contact lenses prevent nearsightedness (myopia) from getting worse?

No, there is no evidence that wearing contact lenses improves vision or prevents myopia from getting worse.

6. Is it safe for me to clean my contact lenses with a homemade solution?

Using commercial saline solutions is the safest method of cleaning lenses. Some studies have shown that homemade solutions may lead to corneal infections. Also see information about contact lenses.

7. How often do I need to get my prescription changed?

There is no predetermined schedule for changing glasses or contacts. It is necessary to change your prescription only when it no longer provide adequate correction. However, it is still a good idea to have regular eye examinations.

8. What is low vision?

Low vision is a term describing a level of vision below normal (20/70 or worse) that cannot be corrected with conventional glasses. Low vision is not the same as blindness. People with low vision can use their sight. However, low vision may interfere with the performance of daily activities, such as reading or driving.

9. Can eyes be transplanted?

No. Currently, there is no way to transplant a whole eye. However, corneas have been successfully transplanted for many years.

10. How successful is corneal transplantation?

Ninety-five to 99 percent of all corneal transplant operations successfully restore the corneal recipient’s vision.

11. Is pink-eye contagious?

Yes, viral conjunctivitis (pink-eye) is very common and is extremely contagious. Avoid touching eyes with your hands, wash hands frequently, do not share towels, and avoid work, school or daycare activities for a least five days or as long as discharge is present.

12. How Do I Prevent Blepharitis?

There are many everyday steps that you can take to prevent blepharitis. This includes removing all eye makeup before bedtime and not applying eyeliner on the back edges of the eyelids behind the eyelashes.

If you are in the early stages of treating blepharitis, avoid the use of eye makeup to prevent further irritation. Once you begin using makeup again, replace your products used in or near the eyelids because they may be contaminated.

13. What is myopia (nearsightedness)?

Nearsightedness is a refractive error that makes distant objects look blurry. It typically happens when the eye is longer than normal causing the focal point to fall short of the retina.

14. What is hyperopia (farsightedness)?

Farsightedness is a refractive error that makes close-up objects look blurry. It typically happens when the eye is shorter than normal causing the focal point to fall behind the retina.

15. Can myopia, hyperopia or astigmatism be prevented?

No. These common focusing errors are the result of a defect in the mechanism of the eyes that is most likely hereditary. However, in the case of myopia, there is some evidence that visual stress caused by too much close work may exacerbate an existing condition.

16. How do cataracts develop?

Age-related cataracts develop when the lens, which consists mostly of water and protein, clumps together. This produces clouding of the lens and reduces the amount of light that reaches the retina and results in glare and seeing halos at night. The clouding may become severe enough to cause blurred vision. Cataracts can also develop from exposure to ultraviolet radiation, eye injuries, eye diseases, certain medications, or diabetes.

17. How do I know if I have glaucoma?

The only way for you to know is to be examined by a doctor. Glaucoma has no symptoms until there is damage to your optic nerve. But there are many routine tests that can identify risk factors and/or presence of glaucoma.

18. Can you have cataracts and glaucoma at the same time?

Yes, you can, simply because both often result as a natural part of aging. But they are not related to one another. And though most people with glaucoma are not at any greater risk to develop cataracts as those without it there are some exceptions. Ask your doctor if you are concerned.

19. What are the symptoms of Eye Floaters?

Eye floaters can appear in many different shapes, such as:

• Black or gray dots

• Squiggly lines

• Threadlike strands, which can be knobby and semi-transparent

• Cobwebs

• Ring shaped

• Once you develop eye floaters they usually do not go away, though they tend to improve over time.

20. What is the Treatment for Eye floaters?

If eye floaters are so dense and numerous that they affect your vision, your eye doctor may consider a surgical procedure called a Vitrectomy. During this procedure, the vitreous and its floating debris are removed and replaced with a salt solution.

21. What is Squint?

A squint is a condition where the eyes do not look together in the same direction. Whilst one eye looks straight ahead, the other eye turns to point inwards, outwards, upwards or downwards. Squints are common and affect about 1 in 20 children. You might even spot that your baby has a squint. Most squints develop before preschool age, usually by the time a child is three years old. Sometimes squints develop in older children, or in adults.

22. How is a squint diagnosed and assessed?

It is important to diagnose a squint (and amblyopia) as early as possible. Routine checks to detect eye problems in babies and children are usually done at the newborn examination and at the 6- to 8-week review. There is also a routine preschool or school-entry vision check.
Some newborn babies have a mild intermittent squint that soon goes. However, fixed squints are usually permanent unless treated.

23. What are the treatments for squint?

• Treating amblyopia (visual loss) if this is present.
• Wearing glasses to correct any refractive error, if this is present.
• Surgery is often needed to correct the appearance of the squint itself, and may help to restore binocular vision in some cases.

24. What Causes Keratoconus?

Tiny fibers of protein in the eye called collagen help hold the cornea in place and keep it from bulging. When these fibers become weak, they cannot hold the shape and the cornea becomes progressively more cone shaped.
Keratoconus appears to run in families. If you have it and have children, it’s a good idea to have their eyes checked for it starting at age 10. The condition happens more often in people with certain medical problems, including certain allergic conditions. It's possible the condition could be related to chronic eye rubbing. Most often, though, there is no eye injury or disease that can explain why the eye starts to change.
Keratoconus usually starts in the teenage years. It can, though, begin in childhood or in people up to about age 30. It's possible it can occur in people 40 and older, but that is less common. The changes in the shape of the cornea can happen quickly or may occur over several years. The changes can result in blurred vision, glare and halos at night, and the streaking of lights.
The changes can stop at any time, or they can continue for decades. In most people who have keratoconus, both eyes are eventually affected, although not always to the same extent. It usually develops in one eye first and then later in the other eye.

25. Can diabetic retinopathy be treated?

Yes. Many of the problems caused by diabetic retinopathy such as swelling of the retina, bleeding in the vitreous and scar tissue on the retina can be treated with modern techniques such as injections, laser or surgery. The earlier problems are found, the easier they are to treat and in general, the better the visual results. Early and periodic dilated eye exams are very important

26. How is a cataract removed?

A small incision is made into the eye. The surgeon will either remove the lens as is, or use ultrasound, a laser or surgical solution to break it up, and then remove it. The back membrane of the lens (called the posterior capsule) is left in place. Usually, a replacement lens (called anintraocular lens, or IOL) is inserted.
