Focus on Autorefractors

RK-F1

Canon Medical Systems
■ The Canon Full Auto-Refractor Keratometer motorized optical head automatically aligns, acquiring readings and automatically moving over to the opposite eye to perform the same function. The unit can also be operated manually to acquire readings.

The RK-F1 replaces the conventional joystick with a trackball and roller. Once the pupil is visible in the monitor, the user presses the start button to begin to complete measurements of refraction and keratometry. For refraction, dioptric measurement range of -30 D to +22 D allows examination of severe myopia and other abnormalities. For keratometry, the radius of curvature extends from 5.5 mm to 10.0 mm.

The RK-F1 can be used to make a series of measurements at a 30° angle from the eye's center along the attentive meridians.

Through retro-illumination, the RK-F1 delivers a detailed view of the eyes that is particularly useful for identifying cataracts, vitreous opacity, scars and other serious eye problems.

A motorized chinrest offers easy adjustment of the unit when beginning the eye examination.

The layout of the operation panel makes the unit easy to use from either a seated or standing position. Control keys for each of the unit's main functions are grouped together for convenience.

3-D WAVE

Marco
■ The 3-D Wave allows users to obtain an autorefraction, corneal topography, optical path difference and wavefront analysis to comprehensively evaluate patients, perform refractive and cataract surgery screenings, evaluate postop complaints and determine pathology diagnoses.

In less than 1 minute, the 3-D Wave gathers data quickly to help determine patient treatment and offers single registration of corneal topography and refraction data, which allows a complete view of the optical system, including a display of internal OPD (subtraction of cornea). Applications range from wavefront contact lens prescriptions to selection of the best IOL to fit a patient's needs.

Wavefront analysis for Vision Diagnostics include: optical path difference, wavefront high-order, wavefront total, eye image showing mesopic and photopic pupils, internal OPD, refractive maps and point spread function.

RETINOMAX AUTOREFRACTORS

Right Medical
■ The Retinomax autorefractor, designed by Nikon, is hand-held and offers features such as full-measurement range and advanced-measurement modes. Readings are taken the instant that alignment and focus is achieved, and terminated when accurate data is gathered.

The Speedy-1 autorefractor and the Speedy-K autorefractor/keratometer, also designed by Nikon, are quick, automated and have a user-friendly interface to significantly reduce testing time and provide accurate, reproducible measurements, says the company.

ACCUREF-K 9001, NVISIONREF-K 5001 AND THE ACCUREF 8001

Shin-Nippon
■ The Accuref-K 9001 refractometer/keratometer combination instrument offers accurate, quick measurement functions, ensuring precise patient data, says Shin-Nippon. Kerato-peripheral measurements are standard. The compact design of the 9001 features a three-position color display screen with control panel adjustment for sitting or standing operator use.

The Natural Vision 5001 autorefractometer/autokeratometer features automatic distance and near point measurements with an Auto-Measure function. A "wide-view window" eliminates "instrument myopia," ensuring quick, reliable patient data, says Shin-Nippon.

The AccuREF 8001's 2.3 mm minimum-pupil feature allows accurate measurements through much smaller pupils than conventional models, says the company. The Quick Measurement Function generates one to 10 continuous measurements with a single touch of the button.

RT-7000 AND RC-5000

Tomey
■ The RT-7000 autorefractor/kerato-meter/topographer takes the place of three devices and has dry eye software inside. The touch-screen alignment of the RT-7000 aligns the eye center with the center of the screen simply by touching the eye shown on the screen. The auto alignment and auto shot functions then start measurement immediately. The RT-7000 combines accurate measurements with short exam time, says Tomey.

The RC-5000 is the newest generation of autorefractor/keratometers. Its features include automatic touch-screen measurements and a high-speed, built-in printer. The touch-screen display allows users to perform both refraction and keratometry automatically with one movement. Users may capture the eye on the display by touching the center of the pupil with a fingertip. The RC-5000 will automatically align and begin measuring. Both devices are EMR compatible.

AUTOREFRACTORS

Topcon Medical Systems
■ Topcon offers a full line of autorefractors, including the new TRK-1P 4-in-1 auto kerato-refractor, tonometer & pachymeter, the KR/RM-8800 series autorefractors/keratometers, the KR-8000PA tri-functional auto kerato-refractor and the KR-9000PW quad-functional wavefront analyzer.

The new 4-in-1 TRK-1P combines an auto refractor, keratometer, non-contact tonometer and pachymeter in one instrument. It features a fully automated measuring process, a large 6.5" color monitor and a built-in printer. The 8800 series also features a color-LCD display and provides measurement through pupils as small as 2 mm.

The tri-functional KR-8000PA incorporates an autorefractor, autokeratometer and color corneal mapping all in one unit, while providing corneal mapping measurements out to 10 mm. The KR-9000PW features a full-range autorefractor, autokeratometer and computerized corneal mapping system, as well as a wavefront analyzer.

iTRACE VISUAL FUNCTION ANALYZER

Tracey Technologies
■ The iTrace Visual Function Analyzer is a combination autorefractor, corneal topographer, wavefront aberrometer, autokeratometer and pupillometer. The iTrace utilizes ray-tracing wavefront aberrometry, capturing 256 data points sequentially in less than 400 milliseconds. By projecting thin-beam laser points into the pupil and charting the retinal location of each data point, the wavefront sensor can calculate the precise amount of deviation induced in the optical system.

The iTrace can provide detailed multi-zonal refraction analysis, and by combining corneal wavefront analysis with whole-eye aberrometry, the iTrace system can isolate whether aberrations originate in the cornea or in the internal optics of the eye.

L80 WAVE+

Visionix, Inc.
■ The L80 WAVE+ combines four functions in one device; autorefractor/keratometer, corneal topographer and aberrometer. The L80WAVE+ utilizes high resolution (3,200 points) Shack-Hartmann technology with an automatic 3-dimensional centering and focusing feature and automatic movement between the eyes. This combination provides a more precise refractometry within 20 seconds, setting up a better starting point for refraction, says Visionix. This technology enables measurement through pupils of small diameters, measurement of the accommodation, size of the pupil and simulation of visual acuity.

ALLEGRO ANALYZER

WaveLight
■ The WaveLight Allegro Analyzer measures the complete optic of the eye and calculates individual wavefront aberrations. The Analyzer enhances the range of possible treatments, from WaveLight's Wavefront-Optimized procedure to sophisticated wavefront-guided treatments, according to the company. Wavefront-guided profiles are based on Wavefront-Optimized profiles for sphere and cylinder.

The Analyzer calculates the individual wavefront aberrations of the eye and works in the visible spectrum. It works with the Tscherning principle and integrates an accommodation target. The Analyzer provides wavefront calculations with Zernike polynomials up to the sixth order and is a precise autorefractor, says Wavelight. The rotating panel PC is both computer and monitor.
