Ezer Autorefractor Keratometer ERK-BH

Ezer Autorefractor Keratometer ERK-BH

This Automatic refractor – keratometer, the Ezer ERK-BH, is a high-quality device, providing excellent measurement precision. One distinguishable feature on this device is the movable LCD display, providing more convenient access to the patient’s eye. The ERK-BH Ezer Autorefractor + Keratometer builds on the excellent feature set and convenient operation of the Ezer ERK-H, to deliver a high-end instrument with unparalleled attention to detail.

AUTO-REFRACTION & KERATOMETRY MEASUREMENT

After a patient is adjusted comfortably using the motorized chinrest, clinicians can take advantage of an enhanced no-load joystick for alignment of the eye. Once aligned, the ERK-BH performs auto-refraction and keratometry with just one press of the joystick button. The ERK-BH can get precise measurements on even the most myopic or hyperopic of patients, with its expansive dioptric measurement range (-30.00 D to +25.00 D). By directing the patient’s gaze to the peripheral fixation lamps, peripheral corneal curvature measurements can be obtained with the tap of a button. The ERK-BH has an equally exceptional range for corneal radius of curvature measurements (5.0 mm to 13.0 mm).

Peripheral Keratometry

Peripheral corneal curvatures can be measured by having the patient look at the peripheral fixation lamps. Measuring the corneal periphery helps with the evaluation of irregular astigmatism, and aids in contact lens fitting. There are two lighting modes for the peripheral fixation lamps: AUTO / MANU.

Comparison of Vision

The CF(Comparison of vision function) mode allows the examiness to experience the corrected vision by applying additional degrees. If the examinee is not presbyopia or primitive, it may be difficult to feel the effect.

Various Measurement Supported

Not only can the practitioner obtain measurements for the usual refractometry and keratometry, but they can also measure corneal diameter and base curve for contact lens fitting. Thus, measurements of the eye and measurements for prescriptions glasses and contact lenses can be obtained more efficiently.

Size MODE

The diameter of cornea can be measured in SIZE Mode for prescribing contact lens. The size of pupil can also measured to see how much it is dilated, and the size of contact lens can be measured without having the examinee remove it.

Illum MODE

By directing light into the pupil using ILLUM mode, cataracts can be evaluated, as can the surface of contact lenses.

IOL Mode

K/R Mode

KER Mode

Intuitive Diameter Measurement

The built-in software of the ERK-BH enables easy diameter measurements using the freeze mode, where measurements of the diameter of the cornea, pupil or hard contact lenses worn by the patient can be taken. By simply touching and dragging the screen with your finger, these measurements are calculated exactly.

Retro Illum Mode

The device’s improved retroillumination mode helps to expose damage to hard contact lenses. In addition, this device has built-in calculations for patients with intraocular lenses or cataracts.

Improved Display Function for Retro illum Mode

Ten images and results can be checked simultaneously through an enhanced display control system.

Convenient Control by TFT-LCD Touch Screen

Operation and setup are a breeze with the ERK-BH’s expanded 7-inch (800×480) LCD touchscreen monitor. Users can avoid neck and back strain with the adjustable touchscreen. It swivels up and down by 180° and left and right from 135-145°. By tapping the appropriate icon, the user can change various settings quickly and easily.

Tilt & Swivel

The screen can be shared from all directions, regardless of the positioning of the patient or the examiner.

Motorized Chinrest

The chinrest is motorized and can be adjusted by the operator using a conveniently positioned switch. This design makes for simple adjustment of the chinrest when switching from patient to patient. The motor is controlled easily by pressing the switch up or down.

Enhanced Joystick Performance

The no-load joystick ensures a softer eye examination, as the user can take obtain measurements without vibrational interference. This system allows for a more accurate measurement as compared to the previous generation belt-type joystick.

Printer with Auto Cutter Function

The ERK-BH provides an immediate and complete printout of measurement results. The auto printer cutter is included for this added convenience. The economy printer mode can be used to save paper by displaying results in a more compact manner by minimizing print size.

Compatible Connection to Various Systems

The ERK-BH can connect to several other digital ophthalmic instruments by Ezer to serve as the hub of the digitally-enabled exam room. Data can be entered manually or transferred directly from compatible devices, and the control box can operate many of the different functions on each device.
