Medical optometry accurately diagnoses the patient's refractive status and abnormal ocular muscle accommodation through the 21-step optometry method. Conventional optometry methods are relatively simple, including retinoscopy, computer optometry, or insert optometry, etc., and the results are rough optometry results; and in medical optometry, in addition to the above inspections, a comprehensive refractor must be used to check the spherical power and astigmatism. The astigmatism axis is fine-tuned to make the diopter detected very accurate.
Ordinary optometry only needs conventional optometry equipment such as computer refractometer, lens box and retinoscopy; medical optometry must be equipped with comprehensive optometry, multi-function visual target projector, corneal topography, and eye axis in addition to the above equipment. Advanced refractive inspection equipment such as measuring instrument and intraocular pressure measuring instrument. The computer optometry examination is fast and convenient, but it can only make a preliminary screening of the refractive state, and must not use its results as the standard of optometry. The comprehensive optometry instrument integrates a variety of inspection functions, and the optometry carried out without the comprehensive optometry instrument is not a medical optometry.
