With the thoughtfully designed GRK-7000, you can consecutively perform the measurement of corneal curvature and determine refractive power in one easy step. With the GRK-7000 auto-fogging mechanism, you can take multiple measurements without worrying about loss of accommodation. You’ll enjoy a wider measurement range as well. Measure contact lens base curvature, pupillary distance, vertex distance, pupil, cornea and iris size with ease and precision. A focusing indicator and real-time images on the 5.7 inch color LCD make operation simple and fast. With a compact, modern design and built-in printer, the GRK-7000 is an ideal choice. Best of all, you can connect the GRK-7000 to other Gilras units to create a Total Refraction System.
