Diagnostic & Specialist - KM-1 LED Manual Keratometer

Being superior in operability, an earth environment-friendly and economical model. Can exert a sufficient performance in ophthalmology and contact lens practice.

  • 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, the astigmatic axis of the eye, etc.
  • The outstanding double external reading helps to read the radius of curvature and refractive power at the same time.
  • The radius of corneal curvature, the 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.
