3.4 Assistant function of Biometry
„ „ „ „ „
This function is an additional function used for biometry purpose,
but it is not a biometry instrument.
This function is intended to provide information to determine the data to
be employed for measurement, by using the B-scan image, in case no
stable biometry results are obtainable with the ordinary biometry instru-
ment due to intraocular disease.
This function which provides amplifying characteristics similar to those
for biometry detects the anterior of the cornea on the line displayed in the
ultrasound image, in an approximate position of the anterior of the crys-
talline lens and that of the retina, to display the cursors in the detecting
position on the line (x-mark: cornea anterior cursor, crystalline lens ante-
rior cursor, and retinal cursor). The mentioned line and each cursor are
movable, while the cursor moves right and left on the line. And this
function displays the distance between the corneal anterior cursor and the
retinal cursor and that between the corneal anterior cursor and the crystal-
line lens anterior cursor. The examiner moves the lines and the cursors to
his/her favorable position, by referring to detected positions.
