: Abbreviation of POST LASIK
: PMMA lens
: After refractive power correction surgery
: Reference section
: Silicone lens
: S/N (signal to noise) ratio
A larger value represents less noise, meaning higher quality
signals can be obtained.
: Digital medical record system to manage data measured with
Tomey products
: Distance between corneal vertexes [mm]
Represents the distance between the corneal vertex and the
posterior surface of the lenses to be prescribed.
When (VD=CL), vertex distance is calculated as 0 mm.
: The LCD turns off automatically when no operation is conducted
for a specified time. (Auto power off mode)
Touch any button to return to Normal mode.
: Manually move the measurement point.
: Indicates the range of gradation values to be measured in
images represented in shades from white to black.
: Adjusts amplification, brightness of images, and amplitude of
waveforms.
: Specifies the range of waveforms to be detected.
: This function smoothes the continuation of images and reduces
noises, improving the image quality.
: Indicates the point where corneal thickness is measured,
specified by diameter and angle.
: Allows you to make various settings, etc. by directly touching
the monitor.
: Image composition method for ultrasound diagnosis which uses
harmonic components of ultrasonic waves.
: Value obtained by converting actual measurements using a
specified percentage or correction value
