Description

Eyeball comprehensive diopter rapid measurement device

Technical Field

The utility model relates to an eyeball diopter measuring device, in particular to a comprehensive diopter quick measuring device for an eyeball, and belongs to the technical field of medical equipment.

Background

At present, research on myopia progression shows that the main cause of myopic eye power increase is eye axis length extension, with power increase of 3.00D per 1mm extension. Medical studies have demonstrated that eyeball elongation depends on retinal peripheral defocus, and that in terms of diopter concept, the person with focus in front of the retina is called myopic defocus and the person with focus behind the retina is called hyperopic defocus.

According to the study of zoology and human eyes, it is proved that the eyeball of a human is of an ellipsoidal special structure, and although the human eye mainly uses the macula area in the center of the retina for viewing objects, the peripheral retinal area is larger than the central retinal area, and more neurons exist, so that the peripheral defocus has a larger influence on the growth and the refraction development of the eyeball than the central defocus.

Diopter of the central field of vision of the human eye is one of the most important parameters for evaluating vision. Research shows that as an effective supplement to the central diopter, the peripheral retinal diopter can reflect the imaging quality of retina, namely the peripheral retinal far vision defocus causes the retinal image quality to be reduced, promotes the growth of the ocular axis and the occurrence and progress of myopia, so that the measurement of the central diopter and the peripheral diopter simultaneously has important value for myopia prevention and control.

The prior vision measurement equipment, such as a comprehensive optometry instrument, mainly measures diopter of a central visual field of a human eye, when the vision measurement equipment is used for measuring peripheral diopter, a subject is required to turn eyes or heads to a fixed target and keep the eyes or heads stationary, the time consumption is long, the degree of fit of the subject is required to be extremely high, and most subjects cannot finish measurement well.

The chinese patent with publication number CN 112263216A discloses a diopter topography measuring instrument, which measures the diopter of human eyes under the sizes of the retinal areas of different macular areas through a diaphragm module with diaphragm holes with adjustable sizes, but the diaphragm module can only determine the diopter of the retinal area of the central retinal area of the macular area of the tested person before use, then select the corresponding diaphragm hole for measurement, because the retinal area of the macular area of each person is different, the diaphragm hole of the diaphragm module is limited, the diopter of the diaphragm module cannot be consistent with the retinal area of the macular area of each person, which results in the measurement process, because the diaphragm hole and the retinal area of the macular area of each person have deviation, the problem of reducing accuracy is solved, and secondly, in order to adapt to the retinal area of the macular area of each person, the diaphragm module can only measure the diopter of the central retinal area of the macular area, can not measure the diopter of the whole retinal area of the macular area, the diopter of the reference data can not be selected, and the accurate diopter result can not be made, meanwhile, because in the cornea reflection diopter and the ocular lens can not be interfered by the refractive eye of the eye can not be measured accurately, and the peripheral diopter of the eye can not be measured accurately.
