The beginning of a new era
Myopia - What's the future?
Philipp Hessler explains the status quo and the possibilities of myopia control with the OCULUS Myopia Master *. The world's first device combines all the important measurement parameters for myopia control: axial length, refraction values and central corneal radii.
Myopia: short-sightedness in children and adolescents on the rise
When it comes to the spread of myopia some studies already speak of an epidemic. The well-known Brien Holden Vision Institute has forecast that by the year 2050 one out of two individuals could be affected by myopia. That is alarming, and it makes it more than clear that early detection and control of myopia are becoming more and more important. For there is no other way to effectively reduce the risks of myopia in children and adolescents.
Numbers speak a clear language
A comparison illustrates the rapidity of this development: In the year 2000 22.9% of the global population were affected by myopia and 2.7% had high myopia beyond -5 dioptres. According to Brien Holden's forecast, by 2050, 50% of the world's population could be myopic and at least 10% could be suffering from high myopia. The development is also dramatic within Europe. According to data recently presented by the European Eye Epidemiology Consortium, more than 47% Europeans between 25 and 29 years of age are myopic
Risk of severe eye disease on the rise
Those affected also have a greater risk of developing severe eye disease such as cataract or retinal detachment and eventual blindness. This development is all the more alarming as more and more of its victims are young .

Causes of myopia
The single greatest cause of myopia is the change in lifestyle.
Tablets, smartphones and laptops today impact heavily on media consumption behaviour. Screen devices of course also pose a new burden on the eyes. In the morning people are in the habit of checking their emails or reading the news on their smartphone while on the subway. This is often followed by long hours of work sitting at a computer. As a result, myopia prevalence is significantly elevated in all instances where the eyes have an especially large amount of short-distance work to cope with. This relates not only to screen time, though there is a clear correlation with the intensity of digital device use.
For example, people in Asia spend an average 14 hours of their day on the Internet, while in the USA it is 6 hours. By contrast, the time spent in outdoor activities in natural bright light in these countries is too very short. Conversely, in Australia, only 30% of 17-year-olds are myopic, and the average Australian spends three hours a day out of doors. This is far more than the maximum one to two hours of the average American, Asian or European, who thus incur a heavy burden on their eye health.
Early and accurate measurement and reliable follow-up of myopia
With myopia prevalence increasing in children, adolescents and young adults and growing exponentially overall, it is becoming more and more important to monitor for myopia early on in life. Simply put: The earlier myopia is discovered, the better. Children should therefore be regularly tested for myopia from the age of 4.
The greatest changes in myopia occur from age 6 to 16. At this stage it is still possible to take suitable measures to help those affected. From the age of 25, by contrast, there is virtually no way to successfully treat eyes for myopia. This demonstrates how important it is to regularly test children already at an early age.
The best combination:
Refraction, axial length and keratometry
The standard method for measuring myopia is by refraction. However, due to day-to-day changes in visual acuity as well as measurement variability, refraction tests are prone to fluctuation and unavoidable measurement inaccuracies.
Axis length measurement
The axial length of the eye can be measured accurately and independently of accommodation . Progression in axial length is a reliable indicator of progression in myopia.
The central corneal radii are what ultimately determines the refractive component of the myopic process . These can be automatically measured and succinctly displayed using a keratometer.
The solution for the future:
The Myopia Master* from OCULUS
Previously there was no all-in-one device available for performing refraction, axial length measurement and keratometry in combination. The only option was to purchase at least two devices, but this still left one with no myopia software.
The Myopia Master* from OCULUS now enables opticians, optometrists and ophthalmologists to position themselves optimally for the future. The Myopia Master combines the most important parameters, making myopia detection and control much easier and more reliable than ever.
