BIOLINE Manual for installation and use
OPTIKON 2000
principal one, allows the axial measurement of this eye to be retained,
even after the double CLEAR . At the time of printing, the measurement
of the reference eye is indicated together with the axial measurement
and the A-Scan graph of the principal eye.
• MODE : Defines the conditions for acquiring the measurement
• APHAKIC : Enables automatic acquisition for an aphakic eye. If peaks
are revealed in the lens zone the message “MODE ERR” (mode error)
is indicated.
• PHAKIC : Enables automatic acquisition with non-cataractic lens.
• CATAR. : Enables automatic acquisition with normal or cataractic eye.
• PS.PHAK.: Enables automatic acquisition in the case of an artificial
lens
• WB.CATA.: For immersion examination (without direct contact between
probe and cornea). Enables automatic acquisition in the case of a
normal or cataractic lens
• MAN.GATE: Mode with manual acquisition via A-SCAN or footswitch
key. In any event an automatic procedure for identifying the type of eye
(phakic or aphakic) is active for the correct calculation of axial length. If
the A-scan is frozen it is possible to measure the axial length relating to
peaks other than the one indicated by the marker (small arrow at the
base of the peak). To move the marker to another peak, display EXAM
= “MAN.GATE” (vertical, then horizontal arrows) then press the key —>
. The marker moves to the next peak and the measurements AXL and
AVG will be updated as a result. Finally press Enter to confirm the
measurement indicated and return to operating mode.
NOTE: AFTER ACQUIRING THE A-SCAN IN ONE OF THE AUTOMATIC MODES, IT IS HOWEVER POSSIBLE TO MOVE
TO “MAN.GATE” MODE IF YOU NEED TO SELECT A DIFFERENT RETINAL PEAK.
• GAIN.: Selects the level of echo amplification; from MIN (minimum) to MAX
(maximum) in seven levels. “MED/HIGH” or “MED.” are the values normally
recommended. There is also the option “GAIN = AUTOSET” which allows
automatic adaptation of the amplification to optimum level.
• PRMT.: Selects the acoustic signalling mode: BEEP for tone signalling, VOX
for voice signalling of the standard deviation.
