Axial Length Measurement: The Gold Standard for Monitoring Myopia Progression

Myopia (short-sightedness) is becoming increasingly common, especially in children and teenagers. While glasses and contact lenses correct vision, they don’t tell the full story of how the eye is changing over time.
At Eyecare Plus Mermaid Beach, we offer axial length measurement, a state-of-the-art technology that allows us to accurately measure and monitor myopia progression. This advanced approach helps us make informed decisions about treatment and long-term eye health for our patients on the Gold Coast.
What Is Axial Length?
Axial length is the measurement of the eye from the front (cornea) to the back (retina).
In myopia, the eye grows longer than normal, causing light to focus in front of the retina rather than directly on it. This elongation is the underlying structural change responsible for short-sightedness.
Because myopia progression is driven by eye growth, measuring axial length has become the most reliable way to track how myopia is changing over time.
Why Axial Length Is More Accurate Than Prescription Changes
Traditionally, myopia progression has been monitored by changes in spectacle or contact lens prescriptions. While helpful, prescription changes can be influenced by:
Day-to-day visual fluctuations
Testing conditions
Accommodation (focusing) responses
Axial length measurement, on the other hand:
Directly measures eye growth
Is objective and highly repeatable
Provides a clearer picture of true myopia progression
For this reason, axial length is considered the gold standard in myopia research and clinical management worldwide.
Why Is Measuring Axial Length Important in Myopia Control?
Measuring axial length allows our optometrists to:
1. Closely Monitor Myopia Progression
By tracking changes in eye length over time, we can accurately determine whether myopia is progressing and how quickly.
2. Assess Treatment Effectiveness
Axial length measurement helps us evaluate whether myopia control treatments, such as Ortho-K, specialised contact lenses, or spectacle lens designs, are effectively slowing eye growth.
3. Identify Long-Term Eye Health Risks
Axial length is also an important indicator of future eye health risk.
When axial length reaches or exceeds 26 mm, the risk of myopic degeneration, including:
Retinal complications
Posterior pole changes
Increased risk of vision impairment later in life
becomes significantly higher.
Early detection allows us to take proactive steps to reduce these risks wherever possible.
How Often Should Axial Length Be Measured?
At Eyecare Plus Mermaid Beach, our optometrists:
Measure axial length at the initial diagnosis of myopia
Repeat measurements every 6 months
This regular monitoring allows us to:
Track progression accurately
Adjust treatment plans as needed
Provide reassurance to parents and patients
