The HandyRef-K is a portable solution for accurate refraction and keratometry measurements anytime and anywhere. The HandyRef-K is lightweight and has excellent weight distribution. Its compact design makes it easy to hold, balance, and use. The intelligently designed button layout is also useful in one-handed operation. New full graphic 3.5-inch color LCD is 40% larger than the previous model. The clear screen design and intuitive icons provide high user-friendliness. Measurement data of 50 patients (100 eyes) can be saved in the main body memory. For inexperienced patients like children, the newly added melody function can ease patient’s anxiety and draw attention. Data can be transferred quickly and easily to PC. Two types of fixation target (scenery or children’s) are available. By using the portable stand, the HandyRef-K can be used as a desktop device. The HandyRef-K adopts an excellent new measurement method; "SynchroScan Technology". Measurements start when the alignment starts, and locks in the data when alignment becomes optimal as a measurement value. Accuracy is further enhanced with the pupil zone imaging method, a super luminescent diode (SLD) and highly sensitive CCD. The features of the HandyRef-K allow easy, accurate measurements while maintaining efficiency.
