Beyond Basic Vision Tests – An Auto Refractor for Myopia, Astigmatism, and Cataract Diagnosis
While auto refractors are often considered basic equipment in ophthalmology, they actually play a pivotal role in determining diagnostic accuracy, clinical efficiency, and patient trust. These instruments not only measure visual acuity, but also allow for precise diagnosis of refractive errors such as myopia, hyperopia, and astigmatism. Furthermore, they help differentiate whether a patient’s visual decline is due to simple refractive issues or indicative of underlying eye conditions like cataracts or dry eye syndrome. As many ophthalmologists treat dozens of patients each day, the demand for accurate and reliable diagnostic tools continues to grow. In response to these needs, we’re excited to introduce the HRK-9000A, Huvitz high-end auto refractor designed to support modern ophthalmic practices.
High-end Auto Refractor Huvitz HRK-9000A
The HRK-9000A goes beyond standard vision tests by offering customized examinations through precise refraction measurements. In addition to assessing visual acuity, it is equipped to detect various eye conditions such as cataracts and dry eye syndrome—delivering far more value than a typical vision test. Let’s take a closer look at the detailed features of Huvitz’s high-end auto refractor.
01.
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 change

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.
Introducing a high-performance auto refractor not only enhances diagnostic accuracy and clinical efficiency, but also builds greater trust with patients—making it a key factor in delivering quality eye care. We hope this post provides valuable insight for ophthalmologists considering the adoption of a high-end auto refractor like the Huvitz HRK-9000A.
