Opthalmic
ultrasound scanners Desmin and Epidot enable estimation of
physiological and pathological structures of eyeball and orbit, full
automatic and manual biometry and calculation of lens power for
intraocular implants. System work in A and B presentation.
Pachymeter
mode enables measurement of thickness of the cornea, which is a
essential prior to certain refractive surgical procedures.

- calculation of average and standard deviation for measurements of individual eye segments
- possibility to make measurement of an eye with lens, with intraocular implant, without lens
B-mode
- distance (3 double cursors)
- area, circumference (ellipse)
- volume (ellipsoid)
Pachymetry
