The best way to keep your lensmeter working is to keep it maintained. As with other instruments, we do a detailed overhaul with our ophthalmic equipment maintenance service. We disassemble the lensmeter, and then disassemble the sub-assemblies, and then systematically clean the parts. The optical surfaces are cleaned, and the power, axis, and reticle are adjusted to give it that "like new" feel. The unit is reassembled and checked on our precision lens sets for optical accuracy, and we use a special alignment tool to align the inker pins to optical center. You'll get a thoroughly cleaned lensmeter, aligned for accuracy and ready to help you care for your patients.
