With the ERK-5400 you can perform refractometry and keratometry alone or consecutively in a single mode.

The ERK-7800 combines all of the necessary visual pretesting functions in one smartly designed instrument. Operators can perform refractometry and keratometry alone or simultaneously. The ERK-7800 is also quick.

The HRK-9000A offers the world's first Contact Lens Fitting Guide with color camera. One of a kind, the device also offers a Meibomian Gland Analysis function and Tear Film Break Up Time (TFBUT) measurement.

The OZMA CRK-9000 Auto Refractor / Keratometer offers high precision measurements using Wavefront Technology and 3D Auto Tracking at an affordable price.

The HRK-8000A has high order aberration data available, which was only previously available in wavefront aberrometers. It also features a contact lens fitting assistance and prescription guide, which has not been featured in an auto ref-keratometer before.

The HRK-7000A autorefractor/keratometer features wavefront technology to provide better results for patients. It has the ability to easily connect to multiple refraction systems.

The CRK-7000 uses 2 mire rings and 2 LEDs to provide corneal curvature radius and corneal refractive power measurements. It features a focusing indicator, a high speed printer, and automatic power-off.

The Visuref 100 is easy to set-up and use, and has a small learning curve. It is comfortable for patients, and has reliable data for quality patient care.

The Canon RK-F2 Full Auto Ref-Keratometer helps accelerate the exam process by aligning and acquiring a reading for one eye automatically. The RK-F2 is lightweight and has a compact footprint.

The WaveLight OB820 diagnostic device is a multi-functional optical biometer used to capture axial eye dimensions and anterior segment measurements. Additionally, the WaveLight OB820 diagnostic device provides information concerning keratometry, white-to-white distance, and pupillometry. OB820 diagnostic device is a multi-functional optical biometer used to capture axial eye dimensions and anterior segment measurements.
