Canon RK-1

This Canon RK-1 is a used autorefractor and keratometer that combines objective refraction with corneal curvature measurement in a single tabletop instrument. It has long served optometry and ophthalmology practices as an efficient way to obtain baseline refractive data and keratometric readings before a full subjective exam. The unit has been inspected and is in working condition typical of a well maintained pre-owned instrument. Designed for ease of use, the RK-1 allows technicians to align the patient's eye with a joystick control and capture automated readings for both spherical and cylindrical refractive error as well as corneal curvature in two meridians. This dual functionality reduces the number of separate instruments needed at a workstation and speeds up patient throughput, which is especially valuable in busy clinics. Its straightforward interface makes it accessible for technicians without extensive specialized training. The RK-1 is well suited to general eye care practices, vision screening programs, and contact lens fitting services that need consistent, objective baseline measurements. It represents a cost effective way for a clinic to equip an exam lane with combined autorefraction and keratometry capability without investing in a brand new system.
