The NIDEK US-500 Echoscan is an ultrasonic device to measure the axial length and corneal thickness and provide the information to be used for diagnosis. Axial length is one of the parameters used to determine the refractive power of an IOL prior to cataract surgery. By inputting the measured axial length with other parameters, the refractive power of an IOL can be calculated. Corneal thickness is a necessary parameter when considering the clinical influence of surgery, drugs and contact lenses upon endothelium tissue. Pachymetry is now commonly performed prior to and after corneal refractive surgery using devices such as the excimer laser. The US-500 is comprised of a touch screen, main body with a built-in printer, Pachymetry probe, and foot switch.

GMDN Preferred Term Name GMDN Definition
Ophthalmic ultrasound imaging system An assembly of mains electricity (AC-powered) devices designed for ophthalmic imaging procedures. It includes software that supports a variety of static and real-time eye and orbital imaging applications including physical measurement and oncology related treatment. It will generate ultrasound pulses, direct them to a target area, detect the resulting ultrasound echoes, and process the resulting information producing and displaying static or dynamic two- or three-dimensional (3-D) images. This GMDN code includes ultrasound imaging systems with, e.g., A-mode, B-mode, Doppler, colour Doppler (CD), M-mode, and duplex (combination imaging, Doppler and/or colour flow) scanning capabilities.
Ultrasound pachymeter A mains electricity (AC-powered), ophthalmic device that uses ultrasound to measure the thickness of the cornea. A small ultrasound probe that is connected to this device is placed directly onto the cornea to make the measurements which are recorded and displayed by the pachymeter. This line-powered device, also known as a pachometer, may provide print-out readings. The data is used to evaluate, e.g., refractive eye surgery (e.g., laser assisted in situ keratomileusis (LASIK) treatment), monitor epithelium regrowth and other ophthalmic needs.
