Agreement of axial length and anterior segment parameters measured with the MYAH device compared to Pentacam AXL and IOLMaster 700 in myopic children

AI Generated Summary*

Right eyes from 60 myopic children aged 7 to 16 years were measured with the MYAH (optical low coherence interferometry), Pentacam AXL and IOLMaster 700. Mean axial length (Pentacam AXL, IOLMaster 700, MYAH) was 23.61, 23.62 and 23.61 mm, a nonsignificant difference (p = 0.06) with an intraclass correlation coefficient (ICC) of 0.999. Keratometry differences (steep, flat and mean) reached statistical significance, yet mean gaps stayed within 0.15 D (ICCs 0.983 to 0.989). Horizontal corneal diameter differed significantly (11.90, 12.11 and 11.96 mm, same order; ICC 0.900), with the largest gap, 0.21 mm, between Pentacam AXL and IOLMaster 700. The authors judged these discrepancies clinically unimportant and the MYAH reliable, noting the retrospective design and small sample.
