The KR-9900 Auto Refractometer Keratometer is an advanced diagnostic platform integrating refraction and corneal curvature measurement into a single high-performance unit. Utilizing 3D autofocus technology, the system automatically focuses and measures both eyes quickly and accurately.
Its mire ring double-ring measurement system enables synchronous focusing and data capture, increasing measurable points and significantly improving keratometry accuracy. The rotation prism ensures evenly distributed light, producing high-quality measurement rings for consistent results.
The KR-9900 supports peripheral keratometry measurement, analyzing corneal steepness within a 3 mm zone around the corneal center for a more complete understanding of corneal shape. A powerful SLD + CCD imaging system ensures reliable measurement even for cataract patients.
With intelligent eye tracking, synchronous PD measurement, RETRO mode, and ergonomic design, the KR-9900 is ideal for busy ophthalmic clinics and optometry practices requiring fast, precise, and comprehensive diagnostics.
