Description

Technical Field

[0001] The invention relates to non-invasive real-time continuous monitoring of intraocular pressure in ophthalmology, and in particular to a full-time dynamic corneal curvature monitoring system and device. Background Art

[0002] The cornea and sclera together form the outermost fibrous membrane of the eyeball. The cornea is also an important refractive matrix and is the only way for external light to enter the eye and form an image on the retina. The surface of the cornea is not a standard sphere. The central 1 / 3 of the front surface is close to a sphere, and the peripheral area is relatively flat. The average radius of curvature of the central cornea is 7.8mm (6.7-9.4mm). Corneal disease is one of the main causes of blindness in my country, and its incidence cannot be ignored.

[0003] Corneal curvature is important for understanding changes in eye morphology, monitoring eye refractive errors, and inferring changes in intraocular pressure. Traditional corneal curvature monitoring is generally instantaneous static monitoring, lacking a 24-hour dynamic continuous monitoring device. Corneal curvature monitoring must be performed in the hospital, which is not only time-consuming and laborious for doctors and patients, but also unable to capture small changes in curvature in a timely manner.

[0004] Chinese patent application CN112450877A discloses a smart contact lens with full corneal fiber grating sensors arranged in series, including a soft contact lens and a hard contact lens; the soft contact lens is placed on the cornea of ​​the patient's eyeball after being worn, and an intraocular pressure monitoring sensor for monitoring intraocular pressure is arranged therein; the intraocular pressure monitoring sensor is a fiber grating sensor, and the fiber grating sensor includes an optical fiber and a plurality of gratings distributed and made on the optical fiber; the plurality of gratings are arranged in the near-central and peripheral areas of the cornea in the soft contact lens, and each grating has a mutually distinguishable reflection wavelength within the intraocular pressure measurement range; the hard contact lens is arranged on the outside of the soft contact lens, and after being worn, the soft contact lens is covered inside and the latter is limited or fixed to prevent the soft contact lens from moving or rotating relative to the cornea. This patent application forms a sensor network through the grating series design, which improves the sensitivity, accuracy and repeatability of intraocular pressure monitoring.

[0005] Chinese patent application CN204394461U discloses a contact lens for continuous dynamic monitoring of intraocular pressure. The contact lens is provided with a lens and a micro-electromechanical system; the lens includes a lens body made of hydrogel cross-silicone hydrogel, and a polyhexamethylene biguanide plasma polymer coating covering the outer surface of the lens body, a hollow channel is provided at the center of the lens, and a conical micro-channel is provided in the non-optical area and the area that does not affect the operation of the micro-electromechanical system; the micro-electromechanical system includes a microelectronic integrated chip implanted on the lens and a signal generator and a signal receiver outside the eye, which are used to sense the changes in corneal curvature caused by intraocular pressure. The contact lens of this patent application has little interference with the ocular surface, and can measure intraocular pressure more accurately, comfortably and safely in real time and continuously, which is helpful for the early diagnosis and early treatment of glaucoma, and can also be used for glaucoma patients to monitor intraocular pressure control.

[0006] The above-mentioned patent, a smart contact lens with full-corneal fiber grating sensors arranged in series, and the patent, a contact lens for continuous dynamic monitoring of intraocular pressure, are attached to the contact lens through gratings and pressure sensors respectively to monitor changes in intraocular pressure at any time. However, it is inevitable that a signal transmission module needs to be set on the contact lens all the time, such as the micromotor system in the patent, which undoubtedly increases the burden on the contact lens and has excessively high requirements for the application of technology.

[0007] In summary, there is an urgent need for a full-time dynamic corneal curvature monitoring system that can separate the monitoring system from the computing and processing system, reduce the difficulty of technical application, improve the system's endurance stability, and reduce the patient's wearing burden.

[0047] In some preferred embodiments, a data storage unit 350 is further included, which can be used for data storage. When the data has no transmission object, that is, the data cannot be transmitted in time, the collected data can be preferentially stored in the data storage unit 350, and then updated and transmitted later; the full-time dynamic corneal curvature monitoring system also includes a data analysis unit 360, which is used for data analysis, comparing the initial value with the previous measurement value, reconstructing the corneal simulation morphology, and obtaining the continuous corneal change law.

The setting of the warning value can be a preset value. For example, when the measured intraocular pressure change interval is greater than a preset threshold, an alarm is issued to indicate abnormality and timely medical treatment;

[0048] Please see attached Figure 2 , attached Figure 2 It is a schematic diagram of steps of a full-time dynamic corneal curvature monitoring system of the present invention; the execution of the full-time dynamic corneal curvature monitoring system of the present invention at least includes the following steps: step S100-step S104;

[0049] Step S100: initialization correction: comparing the corneal initialization data obtained by the full-time dynamic corneal curvature monitoring system with the corneal initialization data measured in advance;

[0050] The patient's initial corneal curvature is measured using an existing keratometer, and then the data is measured by the full-time dynamic corneal curvature monitoring system for comparison and correction to determine whether the error is reasonable. It should be understood that each time the carrier of the corneal curvature tracking module 200 and / or the intraocular pressure detection module 300 is adjusted or replaced, initialization work is required;

The structure is simple, and the detection module is stripped off, which greatly reduces the difficulty of technical implementation and reduces the burden on the cornea.

[0057] Example 2

[0058] Please see attached Figure 3 , Attachment Figure 4 ; Attachment Figure 3 Schematic diagram of a full-time dynamic corneal curvature monitoring device and its magnetic grating corneal contact lens; Figure 4 Schematic diagram of a full-time dynamic corneal curvature monitoring device and its magnetic grating monitoring outer lens of the present invention; a full-time dynamic corneal curvature monitoring device, including a magnetic grating corneal contact lens 40, a magnetic grating monitoring outer lens 50; the magnetic grating corneal contact lens 40 is attached to the cornea, and a corneal curvature tracking module 200 is provided thereon, and the corneal curvature tracking module 200 includes a plurality of magnetic gratings 210; see attached Figure 5 , attached Figure 5 It is a cross-sectional schematic diagram of the magnetic grating groove of a full-time dynamic corneal curvature monitoring device of the present invention; the magnetic grating 210 is fixed in the magnetic grating groove 41, and the magnetic grating groove 41 is arranged on the magnetic grating corneal contact lens 40, and the upper and lower parts of the magnetic grating groove 41 are respectively an upper elastic surface 42 and a lower elastic surface 43, and its periphery is a rigid annular surface 44, which wraps the magnetic grating 210 therein; the magnetic grating monitoring outer mirror 50 includes a frame body 51, and the frame body 51 is provided with an intraocular pressure detection module 300, and the intraocular pressure detection module 300 includes a magnetic grating sensor 310, a central processing unit 320, a power supply unit 330, a signal transmission unit 340, a data storage unit 350, a data analysis unit 360, and an alarm unit 370; and the various interactive units thereof are electrically connected.

The upper and lower surfaces of the magnetic grating groove 41 are elastic surfaces, namely an upper elastic surface 42 and a lower elastic surface 43, and the peripheral surface is a closed rigid annular surface 44 to ensure that the curvature is not affected by horizontal pressure changes.
