Intraocular pressure measuring implant in sclera of human eyeball, terminal equipment and implantation method

Abstract

The invention is applicable to the technical field of ophthalmic medical equipment, and provides an intraocular pressure measuring implant in a sclera of a human eyeball, terminal equipment and an implantation method. A window is opened in the sclera of the human eyeball to make an interlayer, the intraocular pressure measuring implant used for measuring the radial pressure intensity in the sclera of the eyeball is implanted into the interlayer, and the intraocular pressure measuring implant is converted into the pressure intensity (namely intraocular pressure) of the inner wall of the sclera of the eyeball by the external terminal equipment through mechanical calculation and calibration. A sclera flap or a pressure sensor is sewn through a suture line with controllable tension to reconstruct stress, the stress is transmitted to the pressure sensor, at the moment of a surgery, the pressure sensor can be calibrated by adjusting the tension on the suture line, and therefore the immediate measuring capacity is established; and in the long term after the surgery, a sclera tissue gradually heals, meanwhile, the suture line is degraded (if a degradable suture line is used), the sclera replaces the suture line to transmit the stress to the sensor, and therefore the long-term availability is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ophthalmic medical equipment, and in particular relates to an implant for measuring intraocular pressure in the sclera of a human eyeball, a terminal device and an implantation method. Background technique [0002] Glaucoma is the world's first irreversible blinding eye disease. The number of patients with primary glaucoma worldwide will exceed 6 million in 2020, and will exceed 100 million in 2040. China is the country with the largest number of glaucoma patients. In 2022, the number of glaucoma patients in my country reached 21 million, of which 5.67 million were blind. With the acceleration of the aging process, the prevalence of glaucoma increases year by year, and the prevalence of primary glaucoma in people aged 40 and over is 2.3% to 3.6%. The clinical manifestation of glaucoma is mainly the increase of intraocular pressure (Intraocular pressure, IOP), which can lead to slow and irreversible dama...

Problems solved by technology

[0005] The present invention provides an intraocular pressure measuring implant, terminal equipment and implantation method in the sclera of the human eyeball, aiming at solving the problem of using a deformation sensor to measure corneal deformation (the cornea changes shape (curvature) to a certain extent with intraocular pressure) ), the problem with this method is that the combination of the sensor and the corneal surface is not firm and unstable, the deformation transmission is unreliable, and the measurement results are inaccurate; it cannot be worn for a long time, and it is easy to cause problems such as corneal and conjunctival inflammatory reactions
