The first study investigating the repeatability and reproducibility of TowardPi's newly developed swept-source biometer (Zalioth, ZW-30, TowardPi Medical) was published in <Eye and Vision> (IF=4.49) as a cover report (March issue, Fig.1). The results indicated that the new biometer exhibited outstanding intraobserver repeatability and interobserver reproducibility! (ICCs for almost all parameters were higher than 0.900)

Zalioth（fig.3）is based on 1060nm wavelength SS-OCT technology. 25kHz scanning speed is ten times faster than traditional scanning optical biological measurement instruments, requiring shorter patient cooperation time. In addition, Zalioth offers a real-time dynamic view of the entire eye axis during the scan confirms the axial measurement is from the anterior surface of the cornea to the fovea (fig.2), resulting in excellent data accuracy. A comprehensive comparison with IOLMaster 700 indicated that Zalioth ZW-30 displayed excellent agreement about CCT, AQD, ACD, LT, etc, suggesting that anterior parameters and AL measurement data were interchangeable between the ZW-30 and IOLMaster 700!
