Refractors, Ophthalmic, Manual

Definition : Ophthalmic refractors designed to measure the refractive error by changing a set of different lenses mounted in the devices and other settings (also known as manual phoropters or phorometers); these instruments require the examinee's responses. These instruments usually consist of a refraction unit including a set of calibrated (i.e., containing a number of plus and minus sphere and clylinder graduations) lenses, a cross-cylinder, a pulillary distance setting, prisms, lens controls, and an external eye chart. Manual ophthalmic refractors measure sphere power and cylinder power and axis, accommodation, convergence, and binocular balancing of the eyes; they are used mainly to establish eyeglass prescription.
