Description
Monitor - Flexible Vertical-Horizontal Tilt Angle
Monitor 30° left-horizontal tilt allows the user to measure whilst supporting the patient. The 40° vertical tilt enables the user to operate comfortably at standing or sitting positions.
IOL Mode (Colour focus indicator)
Intraocular Lens (IOL) mode allows the possibility to measure eye with implanted Intraocular lens. The Red/Green focus indicator makes alignment easy, especially where irregular reflection occurs with some implanted IOL’s.
Compatibility & Connectivity
K-900/R-800 can communicate with DR-900 Digital Refractor, where REF data can be exported to DR-900 automatically or manually. By one touch on the [Set] button on DR-900 touchscreen panel, objective data is instantly sent to the refractor head.
Additional Information
REFRACTIVE MEASUREMENT RANGE (REF MEASUREMENT)
-
Sphere (S): The K-900 and R-800 measure sphere values from -30D to +22D when VD is 12, and from -22D to +30D when VD is 0. The selectable measurement step is 0.12D or 0.25D.
-
Cylinder (C): The cylinder measurement range is from 0D to ±10D when VD is 0. The selectable measurement step is 0.12D or 0.25D. Cylinder symbols can be switched between -, +, and ±.
-
Axis (A): The axis measurement range is from 0° to 180°, with selectable steps of 1° or 5°.
-
Vertex Distance: The available vertex distance settings are 0, 10, 12, 13.5, and 15 mm.
-
Minimum Pupil Diameter Measurable: The minimum measurable pupil diameter is Φ2.0 mm.
CORNEAL CURVATURE RADIUS MEASUREMENT
The corneal curvature radius measurement specifications are listed for the K-900. In the R-800 column, these values are marked with "-".
Corneal Curvature Radius: The K-900 measures corneal curvature radius from 5.0 mm to 10.0 mm, with a measurement step of 0.01 mm.
Corneal Refractivity: The K-900 measures corneal refractivity from 33.75D to 67.5D, where the corneal refractive index is n = 1.3375. The selectable measurement step is 0.12D or 0.25D.
Degree of Corneal Astigmatism: The K-900 measures the degree of corneal astigmatism from 0D to ±10D, with selectable steps of 0.12D or 0.25D. The display symbol can be switched between mm, -D, and +D.
Axis Angle: The axis angle measurement range is from 0° to 180°, with selectable steps of 1° or 5°.
