The OCULUS Myopia Master®
The All-in-One Device to Support Your Myopia Management
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 optometrists and ophthalmologists to position themselves optimally for the future. The Myopia Master® combines the most important parameters, making myopia detection and management much easier and more reliable than ever.
Start streamlining consultations and practice flow, boosting parent buy-in, and improving myopic patient outcomes today.

Measurement
The all-in-one device for myopia measurements
Refraction, axial length, and keratometry are the main measurements required for professional myopia management, but only in combination do they allow for individualized treatment and counselling. The measurement process is contactless and takes just two minutes.
Reliable and reproducible results
The standard deviation of repeated measurements of axial length is about 0.02 mm equivalent to a refractive error change of 0.05 D.
Data Analysis
Measurement Results Interpreted Based on BHVI Growth Curves
The patient data is compared with ethnicity and genderdependent growth curves collected from more than 20,000 eyes. Exclusive algorithms from the Brien Holden Vision Institute (BHVI) now make interpreting the data easier than ever.
Benefit from an extensive database.
- Normative growth curves by ethnicity and gender
- Measurement data predicting axial length and refraction in adulthood of the right (R) and left (L) eye.
- Color coding of the treatment
- Individual risk evaluation based on data analysis
Risk Assessment
Customizable Questionnaire to Assess Risk & Educate Parents
The Myopia Master® software provides a default questionnaire addressing the most important risk factors: hereditary, environmental, and lifestyle. All information used to assess the severity of risk is based on peer-reviewed papers. Customize the default questionnaire or add additional risk factors.
The Myopia Master® software assists the practitioner in educating children and their parents.
Benefit from the questionnaire or create your own.
- Detailed explanation of risk factor
- Literature sources pop up on hovering
- Prolonged near work predisposes patients to developing myopia
- Color scale for fast risk identification
Myopia Report
Evaluation-based Treatment Recommendations
Based on an evaluation of the results the practitioner can select the appropriate treatment with a simple click or enter a personalized treatment. The Myopia Report for parents and children can then be shared via email or printed out together with the next examination appointment.
All of the results are clearly listed in the Myopia Report, which helps readers to understand their individual outcome.
Benefit from easy-to-understand material.
- Overview of the results analysis
- The digital Myopia Report can be sent by email or printed out together with the next examination appointment.
- Easily select or type in individual treatment recommendations on medication, contact lenses, or lifestyle changes.
NEW: Growth Analysis
Assess Individual Treatment Efficacy
The Growth Control module automatically calculates and visually compares a patient’s axial length growth rate with age-adjusted normative data. Color-coded parameters support easy analysis and explanations to parents and patients about current treatment success or changes to recommendations.
Benefit from treatment and lifestyle recommendations.
- The annual growth rate is automatically calculated from the measurements within the displayed interval and shown in the upper graph.
- Assess each treatment type’s impact on the total axial length for the duration of treatment.
One measurement process, three parameters
Refraction
Determine the eye‘s refractive error in seconds as a fundamental component of myopia management. However, day-to-day changes in visual acuity and measurement variability require additional parameters for professional myopia management.
Axial length
Axial length measurement is considered the gold standard for myopia detection and management. Progression in axial length is a reliable indicator of myopia progression and precedes prescription changes. The Myopia Master® measures axial length accurately and independently of accommodation.
Keratometry
The central corneal radii represent the refraction of the cornea. Combining this with the axial length and the total refraction of the eye enables an even better understanding of the human visual system.
NEW Growth Control Module
Supporting Myopia Management Treatment Efficacy Analysis
Assess individual myopia treatment efficacy at a glance with the support of the new Growth Control software update for the Myopia Master®.
The Growth Control module automatically calculates and visually compares a patient’s axial length growth rate with age-adjusted normative data, facilitating streamlined clinical decisions and discussions with patients and their parents. The color-coded parameters support practitioners in tracking and communicating the effectiveness of each myopia treatment, helping to achieve buy-in and reinforce compliance.
Based on a quantitative analysis of these clinically significant measurements, practitioners can evaluate treatment efficacy to validate success or adjust recommendations with greater speed, ease, and accuracy for improved workflow.

Identify early, prevent later effects
Myopia is a major risk factor for various eye diseases such as retinal detachment, macular diseases and glaucoma. This makes it essential to not only to treat the symptoms of myopia but also to slow down the progression of the disease. The Myopia Master® software offers you innovative tools to provide your patients with the very best care.
GRAS Module – Anything but 0.0.
A New Understanding of Eye Development
Never has the interpretation of measurement results been as easy and reliable as with the new Myopia Master®. All individually measured refractive components of the eye are automatically matched with the Gullstrand standard eye model. This way you can always take your bearings by the gold standard. Not only does this save you time, but it also provides an ideal basis for explaining the results to your patients.
Best of all, OCULUS has introduced patient age as an additional variable, further improving reliability.
Optional Module:
Comparison with the Gullstrand eye
Comparison of individual optical components with the age-adjusted Gullstrand eye
- Simulation of the optical beam path with and without glasses
- Additional information about patient education
- Axial length
- Corneal power
- Crystalline lens power
The Gullstrand Refractive Analysis System or GRAS for short, is a refraction-analysis module that is optionally available with the Myopia Master®.

Partnerships

Partnership between OCULUS and IMI
OCULUS has joined the International Myopia Institute (IMI) in tackling myopia awareness and actively supports the IMI activities to advance the research of myopia to prevent future vision impairment and blindness.
The IMI is a global group of experts who have come together to discuss, debate, and publish the latest evidence-based recommendations in classifications, patient management, and research, in the form of the IMI Whitepapers, in up to twelve international languages.

Partnership between OCULUS and Myopia Profile
OCULUS and Myopia Profile, the world’s largest and most popular myopia educational platform, have formed a partnership to increase eye care practitioners’ knowledge and clinical confidence in measurement and interpretation of axial length in myopia. The resulting educational content, research summaries, and case studies can be viewed on MyopiaProfile.com.

Partnership between OCULUS and BHVI
OCULUS and BHVI (Brien Holden Vision Institute) are pleased to announce an agreement that will see OCULUS incorporate BHVI’s algorithms for tracking and estimating refractive error into its Myopia Master® ophthalmic instruments.
