Takagi KM-1 LED Keratometer

  • The light source changed from a conventional electric bulb type to an LED type which decreases CO2 emission and also reduces the electric power consumption.


  • The Sutcliff type KM-1 can easily measure the radius of curvature, astigmatic axis of the eye, etc.
  • The outstanding double external reading helps to read radius of curvature and refractive power at the same time.
  • The radius of corneal curvature, refractive power of cornea, and extent and axis of corneal astigmatism can be measured.
  • The KM-1 can be set up very easily on any type of instrument table because the base is integrated.
