The Comprehensive Myopia Measurement Tool: Combining an Autorefractor, Axial Length Measurement, and a Keratometer in One Device
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 counseling.

All You Need in 7 Steps
for Your Myopia Management Clinic
1. Measurement
2. Data Analysis
3. Questionnaire
4. Patient Education
5. Treatment Options
6. Take-home Report
7. Follow-up
All information is based on peer-reviewed papers.
Near-work duration alone already provides a good estimate, which can then be narrowed down with further input.

Description
New GRAS Module:
Comparison with the Gullstrand eye
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, 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.
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 will support 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 make available 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 commenced a partnership to increase eye care practitioners’ knowledge and clinical confidence in measurement and interpretation of axial length in myopia. Specific educational content, research summaries and case studies have been developed, which 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.
