A system for producing visual representation of eye structures that includes an ultrasonic transducer, a processor, and a display device. The processor translates electronic signals received by the transducer into image data for display by correlating echo intensities with multichromatic color hues. The processor can also translate the electronic signals by correlating the echo signal intensities with display characteristics, such as brightness, by using gamma curves that have at least one portion that is substantially continuous and non-monotonic. The processor can also translate the electronic signals into an image that shows different characteristics of the electronic signals in different display characteristics (i. e. one characteristic is color coded while another characteristic affects how brightly a color appears). The processor can also process phase information to both emphasize the depiction of eye structure boundaries and aid in distinguishing reverberation echo signals from genuine ones.

A hand-held pachymeter includes an ultrasonic probe capable of emitting ultrasonic pulses and capable of receiving echo signals of the ultrasonic pulses. The echo signals may include an echo signal from an anterior portion of a cornea of an eye and an echo signal from a posterior portion of the cornea. The hand-held pachymeter also includes a hand-held computing device and an expansion module that interfaces the probe to the hand-held computing device. The expansion module includes circuitry to produce digitized signals that correspond to the echo signals, and a memory which stores computer instructions to determine a thickness of the cornea based on the digitized signals. The computer instructions are executed by the hand-held computing device.
