KR-800S AUTO KERATO-REFRACTOMETER Topcon is proud to introduce the new KR-800S Auto Kerato-Refractometer. The KR-800S is unique because it features not only objective autorefraction and keratometry but it also performs subjective far and near testing as well as 3 function tests. These 5-in-1 Functions assure quick and accurate results and enhance your test workflow.

MORE THAN A SIMPLE AUTO KERATO-REFRACTOMETER All measured data can be observed from the wide 8.5 inch color touch screen panel, allowing the user to quickly see each data point and explain the results to the patient. Moreover, Topcon’s ability to engineer a weight reduction of approximately 23%, as compared to older Topcon autorefractors, as well as the new Auto-Vertical mode have contributed to a smooth control of the unit during the measuring process. The KR-800S is more than a simple Auto KeratoRefractometer, it will perfectly match your needs. OBJECTIVE AND SUBJECTIVE DATA Both right...

OBJECTIVE TEST The unique Rotary Prism™ Technology, exclusive to Topcon, allows for unparalleled precision and reliability. Quick measurement becomes available by decentering and rotating the measurement ring projected on the retina rapidly. Moreover, it decreases the influence of an uneven reflection on the eye or a cataract eye. SUBJECTIVE VA TEST* The test results of all objective and subjective measurements can be shown on the monitor. Therefore, it is very easy to compare the VA difference between the objective and subjective tests. If a computerized lensmeter is connected, it can also...

GLARE TEST The Glare test is useful for screening cataract patients by understanding the patient’s VA with/without Glare. The test can also be used to understand the patient’s VA of pre & post LASIK surgery or to know the patient’s QOV. * The Glare test can only be performed with the subjective far distance test. Glare Vision Normal Vision GRID TEST The Grid test can be performed for screening AMD and other macular related diseases. Patients with macular disease may see wavy lines or missing lines. The test can be helpful in detecting early signs of abnormality in the eye so a treatment...
