A Comparison of Optical Biometers Used in Children for Myopia Control

AI Generated Summary*

Axial length and corneal readings from four biometers were compared retrospectively in 22 myopic children (44 eyes; mean age about 11 years, spherical equivalent -3.53 D), with the IOLMaster 700 as reference and 16 children retested on at least one device. Intra-subject repeatability for axial length was 0.05 mm with the reference, 0.06 mm for Myopia Master and Myah, and 0.04 mm for Lenstar, implying waits of 5.0 to 6.7 months before yearly growth of 0.1 mm could be detected reliably. Lenstar read 0.02 mm longer and Myopia Master keratometry 0.21 D lower; J0 differences reached significance but stayed under 0.10 D. Agreement was described as good overall, with at least six months advised between repeat axial checks.
