WHAT IS MYOPIA and WHAT ARE THE CONCERNS?

Myopia, also known as near sightedness, is caused by an increase in eye length or corneal curvature. This causes blurry vision whilst looking at objects far away and clear vision whilst looking at objects up close. 

Myopia is the most common human eye disorder in the world with estimates at 27.3% in Australasia.  It's prevalence has risen to 80-90% in some East Asian Countries. Myopia affects approximately 15% of children between the ages of 6-14.

Myopia in kids tends to progress or get worse throughout childhood, and higher levels of myopia are associated with higher eye disease risks in adulthood. If your child already wears glasses, you can do something to stop their vision worsening. If they don't you can assess their risk of developing myopia.

Myopia development is due to both genetic and environmental factors. One modifiable risk factor is the amount of outdoor time your child experiences daily.  It has been found that increasing outdoor time to greater than 2 hours per day reduces the onset of myopia.

Comprehensive Eye Examinations

At Donvale Optical we have invested in diagnostic equipment to monitor ocular health and vision thereby providing benefits to your vision over a lifetime. 

We use an Axial length scanner to measure the length of the eyeball.  A light beam is shone into the eye to measure the distance between the front surface of the eye and the back surface of the eye.  The measurement is taken in approximately 20 seconds, is very safe, non-invasive and painless. 

By measuring axial length, we can predict those that may develop myopia in the future, evaluate the risk of myopia related eye diseases in the future and evaluate the effectiveness of myopia management treatments

We also use an Optos Daytona ultrawide imaging camera to view the peripheral retina, which is important for higher degrees of myopia where there is a greater likelihood of peripheral retinal degenerations, holes and tears. The Optos Daytona enables retinal views through a range of 200 degrees. By comparison, standard digital retinal photography captures only the central 45 degrees of the retina.

Orthokeratology

Orthokeratology lenses are a form of rigid contact lens which are worn overnight to gently mould the shape of the front surface of the eye (cornea) thereby enabling clear vision all day without the need for daytime contact lenses or spectacles. It improves vision by gently reshaping your eye while you sleep using specially designed therapeutic contact lenses.

You insert the specially fitted orthokeratology lenses at bedtime, and when you awake, you will have clear, sharp, natural vision for your waking hours (without the need for daytime contact lenses or spectacle wear). It is a great alternative to daily contact lenses or spectacles or for those who do not want the risk of surgery. 

We are able to map your cornea and design a therapeutic lens which has specially designed surfaces that reshape your cornea. This improved shape focuses images directly on the retina. The result is clear vision upon awakening and throughout the day.

Orthokeratology FAQ's

 Why should I consider orthokeratology?

If you dislike wear contact lenses or spectacles during the day or if you feel glasses or contacts inhibit your ability to enjoy physical activities such as various sports, running, biking or swimming. Consider orthokeratology for your child if your child has needed stronger spectacle prescriptions every year.

What is involved in fitting orthokeratology lenses?

An initial examination to assess your suitability for orthokeratology which is bulk billed to medicare. A second examination to collect your contact lenses and learn how to insert and remove them. Follow up examinations are at one day, one week, one month and three months. Subsequent examination are at six month intervals. 

Will my orthokeratology lenses hurt?

At first, the lens may be slightly uncomfortable as you get used to the feeling of a rigid lens. Oce your eyes are closed there is generally no feeling, and within a few weeks, even the brief time the lens is on while awake is no longer noticeable. 

Is orthokeratolgy safe?

Very safe. Millions of people around the world wear contact lenses. Orthokeratology lenses have high oxygen transmissibility to the eye. the most common complications include eye irritation and glare upon removal. More serious complications such as acute red eye and bacterial keratitis are extremely rare but they have been reported in the literature. Proper care of contact lenses reduces these risks considerably.
