Luxvision Keratometer KR-800C
 |
Easy to use precision instrument The KR-800C efficiently measures the radius of curvature of the anterior corneal surface. One posicion measurement is not only more accurate but is truly effective in reducing measuring time and also helps promote patient’s cooperation. The brightness of all three images is equal. The central image is double whenever the instrument is not focused precisely on the corneal mire image. This allows continuous monitoring of correct focus by the examiner. |
|
|
Easy to read internal scale system The milimeter escales of the radius curve are located above mire images. Radius of curvatura and diaper escales for corneal refractive power are always visible. |
||
 |
Measurement of corneal astigmatism Horizontal displacement of the mire images indicates existence of astigmatism and axis rotating handle is used to coincide the measuring head with axis, after which the vertical and horizontal knobs are used to coincide the mire images, showing the great case and simplicity of one position measurement. |
|
|
Highly accurate measurements More images are clear and easy to superimpose producing measurements that have little variations. |
||
 |
Multi-Directional Joystick for unprecedented maneuverability Easy, one-handed vertical, horizontal, diagonal adjustment improves performance while decreasing fatigue. |

Components of the KR-800C |
||
 |
||
|
1. Protractor scale Indicates the axis of astigmatism. 2. Adjustable eyepiece control Adjustable from to diapers to correct for operator spherical error. 3. Horizontal knob 4. Axis rotating handle Must be turned to locate the axis of astigmatism when there is horizontal Displacement of the + and - mire images. 5. Vertical knob Is revolved to coincide de + and + marks of the target images for finding the radius of curvature of the vertical axis. Vertical -, horizontal and height adjustment improve perfomance and focus correctly. 6. Operating Rod 7. Up-Down adjustable knob Height of Up-Down adjustable for accurate positioning. 8. Power switch 9. Fluctuation Hand-wheel Is revolved to coincide the-and -marks of the target image for finfing the radius of the horizontal axis 10. Chin-rest 11. Lamp-house 12. Glare shield Helps to maintain fixation by blocking the no measured eye. 13. Headrest |
