Abstract

The invention discloses a wearable intraocular pressure detection device and detection method based on a corneal contact lens grating. The wearable intraocular pressure detection device comprises a wearable bracket and a corneal contact lens, wherein the wearable bracket is used for arranging a light source, a photoelectric detector and a processing circuit, and the light source is used for emitting a light beam; the corneal contact lens is used for reflecting the light beam emitted by the light source, and comprises a transparent grating-free area located in a central area and a grating arealocated in a fringe area of the ; the photoelectric detector is used for receiving a diffraction light beam reflected by the corneal contact lens and converts an acquired light signal into an electricsignal and transmitting the electric signal to the processing circuit; and the processing circuit is used for processing and calibrating data transmitted by the photoelectric detector. The wearable intraocular pressure detection device is based on an optical principle and has the characteristics of small size, simple process, high comfort, internal device passiveness and the like, and can be wornfor a long term to realize continuous measurement.

Description

technical field

[0001] The invention relates to the technical field of ray optics, in particular to a wearable intraocular pressure detection device and detection method based on a corneal contact lens grating. Background technique

[0002] Glaucoma is an irreversible ophthalmic disease. Increased intraocular pressure is the main clinical manifestation of glaucoma. Long-term high intraocular pressure will lead to gradual loss of vision. Therefore, it is necessary to continuously monitor the intraocular pressure of glaucoma patients for a long time for timely prevention and treatment. The traditional intraocular pressure testing instrument is a desktop device with a large volume and complicated operating procedures. It needs to be checked by a doctor or professional nurse after the patient registers in the hospital. This makes it difficult to have a continuous understanding of the real-time fluctuations in IOP. It is not very convenient to control the patient's condition an...
