Precise examination of refractive errors
The micro lens array, independently developed by Huvitz, consists of hundreds of small lenses, providing a wealth of data points for precise diagnosis of refractive errors. The HRK-9000A meticulously analyzes even the minutest details of light aberrations, enabling precise observation of pre- and post-refractive surgery conditions and essential analysis of higher-order aberrations for customized lens prescriptions.


The subjective visual acuity (VA) test
The subjective visual acuity (VA) test finds the best corrective vision through patient communication. It confirms vision based on patient responses, making it useful for determining the need for near-vision correction after distance vision correction. Comparing subjective and objective VA tests yields more reliable and accurate data.
Equipped with TFBUT measurement and a Meibography function
The HRK-9000A features TFBUT measurement and a Meibography function, allowing for a more comprehensive understanding of patients' vision. Through TFBUT (Tear Film Break-Up Time) measurement, you can diagnose tear film condition and dry eye syndrome, while the Meibography function enables the observation of meibomian gland changes.



Detailed eye health analysis through IOL, RET-ILLUM Mode, and Color View Mode
The HRK-9000A uses a separate measurement method for intraocular lens (IOL) or cataract assessment. It allows for the observation of eye health conditions such as lenticular opacity in cataract patients or corneal injury caused by contact lens wear. The full-color CCD camera and white LED light source in the auto ref-keratometer enable the assessment of contact lens fitting status, a feature previously only possible with slit lamps.
