Identity
- Trade Name
- US-500 ECHOSCAN EUDAMEDECHOSCAN FDA UDI
- Generic Name
- Ophthalmic ultrasound imaging system FDA UDI
- Device Name
- 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. FDA UDI
