Orthokeratology Helps Slow Myopia Progression - New Study Update

Levels of myopia (short sightedness) are increasing rapidly, and are expected to continue to do so. Not only do higher prescriptions mean more complicated solutions from spectacles and contact lenses, but it also increases the risks of long term conditions such as retinal detachments. That’s why we are big believers in the latest myopia management solutions.

As optical professionals we rely on the latest evidence to support our work. There is a wealth of data that supports the use of orthokeratology for myopia management, but it’s still nice to see new studies confirming this.

Figure 1.  Myopic progression rates of before and after orthokeratology lens (OK) treatment. The mean myopic progression rate from diagnosis to OK (before OK) is −1.1 D/year, which is significantly higher than −0.3 D/year from OK to last follow up (after OK) (* p  < 0.001, Wilcoxon Signed-Rank test). The mean myopic progression of 1 year before OK is −1.1 D, which is significantly higher than −0.2 D in 1 year after OK (* p  < 0.001, Wilcoxon Signed-Rank test).

July 2019 Study Update

A new study has just been released from Korea, looking at the progression of myopia before and after orthokeratology treatment.

As you can see from fig.1 there was a significant reduction in the progression of myopia from before treatment (average -1.1 dioptres per year) vs after treatment (average -0.3 dioptres per year).

Not only did the prescription change less, but the axial length (length of the eye) stopped growing at the same rate. This is ideal because if the eye grows too much it can stretch the retina which may increase the chances of complications in later life.

What is orthokeratology?

Orthokeratology, or ortho-k is the use of specially designed contact lenses overnight that correct your vision. You sleep with these lenses in and then remove them in the morning. They are designed to correct your prescription whilst you sleep, meaning that you have great vision throughout the day without the need for contacts or spectacles. Not only does this mean freedom from correction, but it’s also been shown to be a great tool in the fight against myopia (as you can see from the study above).
