Product Description

Topcon KR-8000PA Autorefractor/Keratometer/Topographer


  • Mapping / Overlay
  • The KR-8000PA SUPRA provides accurate refraction and keratometry measurements. It also displays corneal mapping very quickly and even overlays the mapping output onto the anterior segment by a single touch.
  • Corneal Irregularity Detection
  • Screenshot 2015-01-12 16.10.42In case of corneal irregularity, the placido ring projected on the cornea will be sort of distorted. However, if the irregularity is not substantial, it will not be noticeable. The KR-8000PA SUPRA detects corneal irregularity like irregular astigmatism and gives a marking to attract the operator’s attention.
  • Base Curvature Area
  • Based on the mapping data, the KR-8000PA SUPRA advises the base curvature for the contact lens. The KR-8000PA SUPRA reconstruct corneal shape from mapping data of the whole cornea obtained by the projected placido rings. The internal software calculates the radius of curvature of a circle consisting of 3 points (2 optic zone ends and corneal peak on the same meridian). 
  • Corneal Diameter Measurement
  • Corneal diameter can be measured either during testing of the patient or later by recalling an image of the cornea on the monitor. Measurements can be obtained for both eyes, with the data recorded on the printouts if required.
  • Printing Measurement Results
  • Screenshot 2015-01-12 16.11.39A complete printout of test results for record purposes can be accomplished with one touch of the print switch. The operator can choose among 3 data formats:
  • Scenic Fixation Chart
  • This scenic color chart is adjustable in two brightness level for optimal results with large or small pupils, making eye fixation easier. 
  • Omni-Directional Joystick
  • Fast, positive and responsive control of operations is performed with our omni-directional joystick that leaves the user one hand free to operate other functions. Even novice operators can obtain excellent results. Also for the KR-8000PA SUPRA, the vertical movement is electric and corresponds to the rotation of the joystick.
  • Auto Shut-Down
  • To conserve enegy and prevent any built-up of heat from electronic circuitry, the instrument incorporates an automated function to shut down the instrument when left unused for more than 10 minutes.
  • Automatic PD Measurement
  • For binocular readings, PD measurement is performed automatically; the value obtained is stored in the patient’s data file and printed out together with the results of objective tests.
