    DIMENSIONS AND WEIGHT Dimensions: 304(W)x521(D)x474-504(H)mm Weight: 23kg PURPOSE OF USE To measure the refractive power of the eye with a function of cornea topography, and to present the measurement data to the eye care professional. OPERATIONS AND PRINCIPLE OF OPERATION To receive light flux from a secondary light source, projected from a light source (point light source) placed at a position conjugate to the eyeground and formed on the retina, by a CMOS sensor through a Hartmann board (formed with a two-dimensionally lined small lens array), and...

    If pupil is detected, the pupil center is used. If pupil is not detected, mechanical center (cornea vertex) is used for analysis. Angle Scale Overlay KR-1W can display angles, horizontal direction as 0°, in 94,147, the aberration map. 148,150 Astig (4mm) Low order astigmatism (with 4mm analysis diameter).
  • Page 202 Used when measuring patient manually. Measuring head can be moved up/down, right/left and back/forth, and a measurement switch is attached. Control Panel Monitor screen to display patient's condition and analysis 12,16 results. As KR-1W adopts touch panel system, it is also used for operation. TERMINOLOGY...
  • Page 203 D (diopter, corneal refractive power) and mm (corneal curvature radius). DATA OUT button Function button on the measurement screen of main body. In KR-1W, this is used for printing measurement result by internal printer, or for transmitting data via net- work. Diameter Pupil diameter.
  • Page 204 IOL Mode Hartmann image may become unmeasurable on eyes wearing IOL and eyes suffering cataract. In this case, KR-1W, using IOL mode, can change cam- era's exposure time and lower error rate.

  • Page 206 Means bright place measurement. Placido ring Ring-shaped part around the measuring window of main body. In KR-1W, measuring beam is projected from Placido ring, and the measured cornea shape is calculated by receiving the ring beam reflected by patient's cornea sur- face.
  • Page 207 Means dark place measurement. Screen Layout Custom layout to select and display maps and RMS as desired. In KR-1W, screen layout can be prepared up to four types. Screen Shot Output Function to data-output analysis result screen. KR-1W outputs the analysis result screen displayed in main body in bit map style.
