Ophthalmic A Scan

Ophthalmic A Scan (SW-1000A/P) is composed of main unit, A scan probe, P scan Probe, pedal and so on. The A scan probe contacts the cornea and sends out ultrasound of 10 MHz. The echo wave from front surface, back surface of lens and retina is respectively detected. The signal is processed and then we get the depth of chamber, thick of lens and axial length. The data are transmitted to MP (Micro Processor). The values of A constant and K1, K2 are input from keyboard. The MP automatically calculates the IOL according to the chosen formula (Default formula is SRK-II), data and values of A constant and K1, K2. The data of IOL are displayed on the color LCD screen through output interface, or stored in the machine, or printed out.
