Common Technical Specifications Downloads

Since 2008, the Japan Ophthalmic Instruments Association (JOIA) has been investigating the ophthalmologic examination workflow to promote/publish standardized technical specifications of the output data from ophthalmic examination instruments in cooperation with IHE-J and the Japanese Ophthalmological Society,

JOIA has already published the common technical specifications of output data for several ophthalmic instruments such as refractometers, tonometers, lens meters, fundus cameras, axial-length/cornea-thickness measuring devices and IOL power calculation devices. 

JOIA hopes all the member manufacturers to implement these standardized data output specifications to their products.
