Rexxam Digital Auto Refkeratometer
Auto Refkeratometer is an easy to use and compact device used for effective eye examination. Made up of advance technology, it offers quick and accurate measurements. The high-quality, modern design of the Refkeratometer enables faster operation and convenience in usage. We are Importer, Wholesaler & Supplier of REXXAM ACCUREF K-900/R-800 Auto Refractometer in India.
An Refkeratometer is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses. This is achieved by measuring how light is changed as it enters a person's eye. The majority of autorefractors calculate the vision correction a patient needs (refraction) by using sensors that detect the reflections from a cone of infrared light.
The Refkeratometer automatically determines the correction needed to place your "focus point" on top of the retina, the light-sensitive area at the back of the eye responsible for correctly processing images. The measurement taken by an Refkeratometer can be translated into a prescription for eyeglasses.
An Refkeratometer Focus light into the eye, measuring how it changes as it bounces off the back of the eye retina. Then, the patient is shown an image that moves in and out of focus. The Refkeratometer automatically determines the correction needed to place your "focus point" on top of the retina, the light-sensitive area at the back of the eye responsible for correctly processing images.
The majority of Refkeratometer calculate the vision correction a patient needs (refraction) by using sensors that detect the reflections from a cone of infrared light. These reflections are used to determine the size and shape of a ring in the retina which is located in the posterior part of the eye.

Auto RefkeratoMeter ACCUREF K-900 "GOOD DESIGN AWARD 2011"
New Generation DESIGN & STYLE
Exquisite detail and quality. Sophisticated shape combined with soft curves and the attractive color with high quality two-tone metallic and pearlescent paintwork which complements any interior and appeals atmosphere of trust to the customer.
Feather-touch sensor button
The feather-touch sensor button used to interface with the screen enables sensitive and accurate operation.
Newly designed optical unit with further improved accuracy
The newlby designed optical unit allows measurement of the minimum pupil diameter up to 2.0 mm and high-accuracy measurement.
Useful function for actual measurement such as display of reliability warning indicator has been added.
Improved side flaps,head rest and chin rest
Side flaps mounted to each side of the measurement window enabling to block out the light realizes high accuracy. The modified shapes of the forehead rest and the chin rest help to minimize stress of the patient.
New Joystick
The completely redesigned joystick with the shape and top button allows the operator to control the unit with more precise and instinctive movement.
Newly designed IOL Mode [color focus indicator]
A subject with IOL was conventionally difficult to measure but this newly designed IOL mode has made it much easier.
Scotopic & Photopic Pupil Diameter Measurement
Both scotopic and photopic measurements are available.
※ S.P.S：Scotopic Pupil Size P.P.S：Photopic Pupil Size
Unique LCD Monitor
A swivel function to the left (30°) and a vertical tilt function (40°) have been added to the monitor unit. This swivel function allows measurement while supporting the patient.
