The KT-800 is an accurate and easy to use non-contact tonometer, designed with the patient's comfort and the operator's need for functionality in mind. Auto alignment simply requires placing the positioning spot inside a circle on the monitor after which 3D alignment is automatically carried out by the tonometer. The instrument will only detect and measure when the patient's eye is sufficiently open for a reading in order to carry out measurements in a comfortable and time efficient manner. The tonometer chin rest can be easily adjusted and allows visual contact with the patient throughout the measuring process. In addition, the gentle air puff feels incredibly "soft" to the patient, thus ensuring patient comfort. The pressure measurement range covers pressures of 1 to 60mmHg without any switching and the results are swiftly printed on paper or transferred to your Electronic Health Records.
