Are You A Candidate?

Common Vision Disorders


Myopia (Nearsightedness)

Nearsighted individuals typically have problems seeing well at a distance and are forced to wear glasses or contact lenses. The nearsighted eye is usually longer than a normal eye, and its cornea may also be steeper. Therefore, when light passes through the cornea and lens, it is focused in front of the retina. This will make distant images appear blurred.  There are several refractive surgery solutions available to correct nearly all levels of nearsightedness.

Hyperopia (Farsightedness)

Farsighted individuals typically develop problems reading up close before the age of 40. The farsighted eye is usually slightly shorter than a normal eye and may have a flatter cornea. Thus, the light of distant objects focuses behind the retina unless the natural lens can compensate fully. Near objects require even greater focusing power to be seen clearly and therefore, blur more easily.

Astigmatism

Asymmetric steepening of the cornea or natural lens causes light to be focused unevenly, which is the main optical problem in astigmatism. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common.

Presbyopia

Presbyopia is a condition that typically becomes noticeable for most people around age 45. In children and young adults, the lens inside the eye can easily focus on distant and near objects. With age, the lens loses its ability to focus adequately.

Although presbyopia is not completely understood, it is thought that the lens and its supporting structures lose the ability to make the lens longer during close vision effort. To compensate, affected individuals usually find that holding reading material further away makes the image clearer. Ultimately, aids such as reading glasses are typically needed by the mid-forties.


How do I know if I am a candidate for LASIK?

  • Up to 11.00 D myopia (near sighted)
  • Up to 3.00 D hyperopia (far sighted)
  • 5.0 D or less of astigmatism
  • Minimum age 18
  • Maximum age 65
  • No systemic or eye diseases affecting outcome

The most common reasons for not being a LASIK candidate include thin corneas, severe dry eyes, and/or cataracts or other eye diseases. Many people think that astigmatism or large pupils dictate that they are not a candidate, however, modern improvements in laser technology have made it so that surgery is a definite possibility for individuals with these issues.

In order to confirm that you are eligible for laser surgery, you must schedule a LASIK evaluation with Dr. Walter.
