    1.4 Outline of the operation This model of UD-6000 is designed an ophthalmic diagnosis instrument, which provides the function acquires the ultrasound cross-sectional image of an eye with the ultrasound oscillators enclosed in the probe, that which acquires the A-scan wave shape, and that which measures the axial length. It is noted that the instrument is in suspension of ultrasound wave transmission.

  • Page 21: Biometry Function

    1.4.4 Biometry function The probe connected to this instrument transmits ultrasound waves into the internal part of the eyeball, while the ultrasound echo reflected from its anatomy will be received by the same probe. The instrument measures the time from the echo for corneal epithelium to that for the object to be measured, with which the length of the tissues is calculated by applying the sound velocity for conversion as set.
