Can myopia calculators accurately predict children’s myopia progression?
This study investigated the accuracy of the Brien Holden Vision Institute (BHVI) myopia calculator in predicting myopia progression. The extent of myopia progression over 1-2 years in children corrected with single vision spectacles was accurately predicted by the BHVI myopia calculator in 32-38% of 7-13 year old Hong Kong children. Around one-third progressed more and one-third progressed less than the range predicted by the calculator.
