Refractive errors incidence / prevalence

Refractive errors are the most common type of vision problem that affects your vision and makes it difficult to see clearly. They happen when the shape of your eye affects the ability for light to focus properly on the retina (the photographic film of the eye).

There are 3 main refractive errors that can affect your eye:

  • Myopia (short-sightedness).
  • Hypermetropia (long-sightedness).
  • Astigmatism (difficulty focusing at most distances).
  • Presbyopia (loss of accommodation making reading up close difficult without glasses).

A refractive error can happen as a result of one, or a few, of the following:

  • A change in the eye’s shape.
  • A naturally steeper or flatter surface of the eye.
  • A thicker or thinner lens than normal.
  • The eye is too short or too long.

Often refractive errors are genetic in origin but can be affected by lifestyle, in particular, the amount of near work during the development of the eye in your younger years.

  • During your visit to IVISION LASER we will perform a comprehensive examination of your eye. This includes refraction tests performed by our very experienced optometrist to detect the exact nature of your refractive error.
  • Other diagnostic tests such as the Pentacam HR and MS39 give us an accurate assessment of the curvature and astigmatism in the cornea and help assess your suitability for laser eye surgery.

What is the common treatment for refractive error?

Glasses and contact lenses are used primarily to assist patients with refractive error.

Laser vision correction is an excellent way to treating refractive errors permanently such that you can have natural clear vision.

Can I still have laser eye surgery if I have astigmatism?

If you’ve avoided pursuing surgical options to reduce your dependency on glasses and contact lenses simply because you’ve been told you have astigmatism, LASIK or SMILE Pro for astigmatism may be the answer.

For patients who are unsuitable for the LASIK or SMILE Pro for any reason, there are additional options for surgical correction of astigmatism, including PRK and lens surgery procedures.

Does a high prescription make me unsuitable for vision correction?

We can use laser eye surgery to treat:

  • Short-sightedness – also known as myopia (from -0.5 units to -10 units)
  • Long-sightedness – also known as hyperopia (from +0.5 units to +4 units)
  • Astigmatism (up to 6 units)

For patients who have higher prescriptions lens surgery can be used to correct prescriptions of higher levels.

The best way to find out is to complete our online suitability test and book in for a free assessment at IVISION LASER.

Can I train my short-sightedness away by not wearing glasses?

No you cannot train your short sighteness away. Short-sightedness occurs when the length of the eyeball is too long for the refractive power of the eye. This can only be corrected with glasses or contact lenses or more permanently with laser vision correction.

Is it covered by health funds or Medicare?

There are some health funds that cover laser vision correction. Since this is constantly changing it is best to check with your health if they cover laser vision correction or not. There is no rebate from Medicare.

Learn more about refractive errors through these online resources

Expand your knowledge about refractive errors. (These links will take you off our website.)

A refractive error is the most common eye problem. When the shape of the eye is abnormal, the eye doesn’t bend (or refract) light properly, and so vision is blurred.

The most common types of refractive errors are:

  • Long-sightedness (hypermetropia), causing blurred close and distance vision.
  • Short-sightedness (myopia) causing blurred long distance vision.
  • Astigmatism, which causes an uneven focus of light and blurred vision.
  • Presbyopia, When the eye lens loses flexibility, making close work difficult. This is most common with people over 40 years of age.

This seminal paper covers the prevalence, associations, and characteristics of severe uncorrected refractive error in the Australian National Eye Health Survey. These astounding results encompass increasing public awareness around the importance of regular optometric examinations in groups at high risk of severe uncorrected refractive error. Click here for more information.

Refractive error causes half of all vision problems in Australia. Between 200,000 and 300,000 Australians are not seeing as clearly as they should be because of under-corrected refractive error. For example, wearing glasses with an out of date prescription.

Refractive errors are caused by:

  • too much or too little growth in the length of the eyeball
  • problems with the shape of the cornea, or
  • ageing of the lens.
  • Both genetic and environmental factors contribute to refractive error.
