KR-1 - refractometers
The Topcon KR-1 is a revolutionary auto kerato- refractometer. The tiltable and rotatable touch screen will change the way of working for ever. The operator can use the KR-1 from various angles, ensuring the best interaction with the patient. The Topcon KR-1 can be used in several set-ups, which use a minimum of working space.
• Fully automated operation with touch screen
• Flexible & space saving lay out
• Reliable & fast measurements
• Compact ergonomic design
The KR-1 is fully operated through a 8.5” wide touch screen. Simply touch the center of the pupil on the LCD screen to start measuring both eyes. The device automatically obtains objective refraction data of the right and left eye. The KR-1 auto kerato- refractometer can detect automatically abnormal conditions of an eye, i.e. cataract. The instrument changes to “cataract mode’ and continues the measurement. The device incorporates a button for cataract, in case you would like to start measurements in the cataract mode from the start. If required, the KR-1 can be set in manual mode as well. The manual mode is used for focusing only. The up/down and left/right movement will remain automated.
The adjustable touch screen control panel enables the operator to be positioned anywhere around the patient because the control panel can be faced in a number of different directions. The KR-1 can be positioned in a conventional set-up, against a wall, or even in a corner of a room. The compact body enables the operator to support the patient easily from many different positions during measurement even when the patient's eye lid needs to be opened. These unique aspects will contribute to space saving and flexible layout in your eye examination room.
With Topcon’s exclusive Rotary Prism Technology, the KR-1 auto kerato- refractometer provides unmatched accuracy and reliability. This technology ensures reproducible results. The objective measurement of both eyes is done in a fast and comfortable way for the patient. The KR-1 can measure patients with a pupil as small as Ø2mm
The Topcon KR-1 allows the operator to take peripheral KRT measurements of the corneal curvature radius, in addition to inner KRT ring measurements, which is useful in corneal evaluation of contact lens fitting.
The KR-1’s new ergonomic design provides a more comfortable position for the patient with a 5º inclination of the patient’s head, and optical head of the KR-1. The compact body of KR-1 and improved chin rest design enables easier access to patients. The operator will have better interaction with the patient.
The KR-1 can be connected directly to other instruments such the Topcon CV-5000 automated phoropter. The KR-1 can be integrated into the Topcon Imaging and database software: IMAGEnet i-base. This software enables easy and fast access to patient data and is a useful tool to maintain customer contacts.
