Problems solved by technology
This measurement has the following limitations: First, the conditioning stimulus given is only static
The second is that the adjustment stimulus given is not the real adjustment amount of the eyes, and the eye's response to the adjustment stimulus is ahead or lagging behind, so it is impossible to obtain an objective adjustment amount
The third is that the morphological measurement is not measured synchronously with the accommodation response of the eye

The invention relates to a device and method for synchronously measuring eye objective adjusting and biological parameters. The method includes: a, a computer controls an optical coherence tomography (OTC) imaging module, an external stimulation sighting mark module and an infrared optometry module to synchronously measure the biological parameters and the objective adjusting variables of eyes, and the three modules respectively adopt light sources of three different wave bands; b, light beams of three different wave bands are irradiated into the same position of the eyes, and the light beams of the three different wave bands and irradiated from the eyes are simultaneously and respectively obtained through the OCT imaging module, the external stimulation sighting mark module and the infrared optometry module; c, an external pedal is simultaneously connected with driving programs of the three systems, and the same trigger signal controls the OCT imaging module, the external stimulation sighting mark module and the infrared optometry module simultaneously. By means of the device and method, eye objective adjusting and biological parameters can be synchronously measured.
Description
technical field [0001] The invention relates to the field of optoelectronics, in particular to a method and a device for synchronously measuring objective adjustment and biological parameters of eyes. Background technique [0002] Eye adjustment refers to the use of changes in the position and shape of structures such as the lens to change the refractive power of the eye's optical system, so that objects at different distances can be clearly imaged on the retina. Regulation is closely related to many clinical problems or phenomena, such as myopia, presbyopia and asthenopia, etc. The research on the mechanism of regulation is crucial to the study of the causes of presbyopia and asthenopia and the in-depth study of the development mechanism of myopia. The current studies on the accommodation and morphology of the intraocular medium (mainly the lens) generally only involve applying one accommodation stimulus to the eye and measuring the morphology of the eye under several accom...
