The newer generation of ultrasonic pachymeters. work by way of Corneal Waveform (CWF). Using this technology the user can capture an ultra high definition echogram of cornea, think of it as a corneal A-scan. Pachymetry using the corneal waveform allows the user to more accurately measure the corneal thickness, have to ability to check the reliability of the measurements that were obtained, have the...
