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.
Improved usability
Melody function – for inexperienced patients like children, newly added melody function can be of help. It can ease patient’s anxiety and draw attention.
Measurement method
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.
