ABOUT THE CALCULATOR AND NEW UPDATES

The Brien Holden Vision Institute myopia calculator is designed to bridge the gap between research data and the end user. The tool shows the various management options / scenarios and demonstrates the possible benefits, over time, of starting to treat myopia progression.

The Brien Holden Vision Institute myopia calculator tool helps eye care practitioners, individuals and carers to apply the research based evidence for various management options and enables the practitioner to demonstrate and discuss risk versus benefit for individual cases.

This latest version of the Brien Holden Vision Institute Myopia Calculator requires users to complete a one-off registration to access it. This will enable us to better understand the number of users and allow for notifications about any updates to the calculator or advances in myopia management research. You can opt out of these notifications at any time and still continue to use the product.

The calculator is now available in two additional languages – Mandarin and Spanish – and we hope to add further languages in the future. You can now choose your preferred language and switch at any time.
This new version includes an ‘ethnicity’ option which allows you to switch between ‘Asian’ and ‘Caucasian’. The updated Myopia Calculator can be used to estimate the annual progression of myopia with and without management using:

- Age
- Refractive error at presentation and
- Ethnicity

The estimated annual progression was calculated using data from the Brien Holden Vision Institute database (for Asian ethnicities) and published meta-analysis (for Caucasian ethnicity).

The estimated annual progression is enveloped by a band (the 95% confidence interval) which means that an estimated observation using the data sets is likely to fall within that band with 95% probability. The band increases in width for longer durations as the confidence decreases with longer observation periods.

Using the “estimated annual progression without management” as a comparison, the calculator can be used to determine the extent to which the risk of annual progression can be reduced with a specific myopia control strategy.
We hope you enjoy the new additions and features.

UPDATED CALCULATOR FEATURES

SINGLE SIGN-UP

This latest version of the Brien Holden Vision Institute Myopia Calculator requires users to complete a one-off registration to access it. This will enable us to better understand the number of users and allow for notifications about any updates to the calculator or advances in myopia management research.

MULTIPLE LANGUAGES

The calculator is now available in two additional languages – Mandarin and Spanish – and we hope to add further languages in the future. You can now choose your preferred language and switch at any time.

ETHNICITY ADDED

This new version includes an ‘ethnicity’ option which allows you to switch between ‘Asian’ and ‘Caucasian’. The updated Myopia Calculator can be used to estimate the annual progression of myopia with and without management using age ,refractive error at presentation and now ethnicity

REVISED INTERVALS

The estimated annual progression is enveloped by a band (the 95% confidence interval) which means that an estimated observation using the data sets is likely to fall within that band with 95% probability. The band increases in width for longer durations as the confidence decreases with longer observation periods.

MANAGEMENT OPTIONS

Choose from different myopia management options, including: multifocal soft contact lenses; peripheral defocus spectacles; executive bifocals; progressive addition spectacles; orthokeratology; low and high dose atropine.

PEER REVIEWED DATA

All data is sourced from peer-reviewed reports on well-conducted clinical trials. The estimated annual progression was calculated using data from the Brien Holden Vision Institute database (for Asian ethnicities) and published meta-analysis (for Caucasian ethnicity).

CONTROL RATE

Use the ‘control rate (%)’ slider to change the level of myopia control and view how it will impact on progression of myopia across the range reported for the selected treatment, compared to standard correction, e.g. single vision spectacles.

RESPONSIVE

Although the calculator is created primarily for desktop and tablet use in your practice, the responsive design ensures it will perform on all devices (including smart phones).
