Supine position mode – by tilting the instrument 60º or more downward, it enters supine position mode automatically. When measuring from patient’s side, the cylinder axis is compensated by 90º, and is displayed.
Melody function – for inexperienced patients like children, newly added melody function can be of help. It can ease patient’s anxiety and draw attention.
Pupil zone imaging method – analyses a wide area (Max. 4 mm diameter) pupil zone. By measuring the light coming through the pupil zone in a wide area, more accurate measurement data closer to the subjective refraction is now possible.
SynchroScan Technology – adopted an excellent new measurement method; “SynchroScan Technology”. Measurements start when the alignment starts, and locks in the data when alignment becomes optimal as a measurement value. It provides a more stable measurement value more effectively and efficiently.
Auto shot mode – when the alignment / focusing becomes optimal, it gets the measurement data automatically. If unstable data is included, additional measurement automatically starts.
