A Phoroptor is an important part of your practice, and we take their maintenance seriously. Every unit we clean gets the same thorough treatment. We disassemble the phoroptor unit, clean the bearings, races, and optical surfaces. We disassemble the cross cylinders, clean out the old grease, re lubricate, reassemble and align the instrument. We adjust the PD mechanism, sphere detents, and cylinder axis tension. Then, we check it with our alignment jig and make sure the unit is on axis and optically correct. You can rest assured that your phoropter, when maintained by proper technicians will last longer and maintain resale value.
