Full-Auto ARK-Biometer Refractometer System for Hospitals

The Visionstar is a Class II ophthalmic optical instrument—specifically an auto refractometer-keratometer—powered by electricity, with CE quality certification , ensuring compliance and reliability for clinical use. Equipped with a 9-inch adjustable touch screen, it enables intuitive operation while delivering high-precision ocular measurements: its sphere power range covers -30D to 30D, cylinder power (absolute value) spans 0 to 12D, and cylinder axis adjusts from 0° to 180°, meeting diverse refractive testing needs. For corneal parameters, it measures curvature radius (6.5~10.5mm) and corneal refractive power (32.1D~51.9D) accurately. Additionally, it detects pupil diameter (2~14mm) and pupillary distance (10~85mm), providing comprehensive data for vision correction. A built-in 57mm thermal printer with automatic paper cutting allows for quick output of test reports, enhancing workflow efficiency. Designed specifically for ophthalmic optical applications, this device serves as a practical tool for optometry centers, optical shops, and ophthalmic clinics, supporting precise vision assessment and glasses-fitting processes.
