Abstract
Description
Technical Field
[0001] This invention relates to the field of eye health monitoring technology, specifically to a wireless system and method for acquiring intraocular pressure data. Background Technology
[0002] Glaucoma and other blinding eye diseases have become major irreversible causes of blindness worldwide, and intraocular pressure (IOP) is a core monitoring indicator for its screening, diagnosis, treatment, and long-term management. Current IOP data acquisition technologies are mainly divided into three categories: in-hospital single-point measurement, independent implantable continuous monitoring, and patient-led intermittent home monitoring.
[0003] In-hospital measurements, exemplified by the Goldmann applanation tonometer, can only obtain discrete data at the time of visit; home tonometers rely on patient self-operation, resulting in sparse and fragmented data. Neither method covers key periods such as nighttime, changes in body position, and emotional fluctuations, easily missing transient intraocular pressure peaks and failing to accurately reflect the dynamic changes in intraocular pressure.
[0004] Independent implantable continuous monitoring devices achieve continuous measurement by implanting miniature sensors inside the eye, but they require the integration of power supply and wireless transmission modules, which presents many inherent bottlenecks: the built-in battery has limited battery life, usually only a few months to a few years, requiring a second surgery to replace it, increasing patient trauma, risk and economic burden; active radio frequency sampling and transmission are prone to generating continuous heat, posing a risk of thermal damage to intraocular tissues; fixed frequency sampling generates a large amount of redundant data, resulting in high energy consumption and serious transmission conflicts.
[0005] Furthermore, existing data acquisition strategies are mostly based on preset fixed patterns, lacking adaptability. They cannot dynamically adjust the sampling frequency according to the stability or fluctuation of intraocular pressure, the patient's physiology, and the usage scenario. This results in low energy efficiency and difficulty in prioritizing the capture of key data. At the same time, sensor data is easily affected by environmental factors such as body temperature, leading to drift. They lack real-time online compensation and calibration, and also lack synchronous contextual information such as body position and proper movement, resulting in insufficient data reliability and clinical interpretation value.
[0006] In summary, existing technologies struggle to balance long-term security, data integrity, system energy efficiency, and user-friendliness, failing to meet the clinical needs for long-term, accurate, and intelligent intraocular pressure monitoring for eye diseases such as glaucoma. Summary of the Invention
[0007] In order to overcome the shortcomings of the existing technology, the present invention aims to provide a wireless acquisition system and method for intraocular pressure data, so as to solve the technical problems of data partiality, electromechanical bottleneck, rigid strategy and insufficient quality in the long-term intraocular pressure monitoring of existing data acquisition technology.
[0008] This invention is achieved through the following technical solution: This invention provides a wireless acquisition system for intraocular pressure data, including an intelligent artificial lens, an external portable reading device, a user terminal, and a cloud service platform; One end of the intelligent intraocular lens is interactively connected to one end of an external portable reading device, the other end of the external portable reading device is interactively connected to one end of a user terminal, and the other end of the user terminal is interactively connected to a cloud service platform.
[0009] Preferably, the intelligent intraocular lens includes a passive sensor module, an optical component, and a support haptic module; The passive sensor module is integrated at the root of the optical section and the support loop module; The passive sensor module is interactively connected to an external portable reading device.
[0010] Furthermore, the passive sensor module includes a pressure sensor, an ASIC chip, a micro coil, and a temperature sensor; The output terminals of the pressure sensor and temperature sensor are connected to the input terminal of the ASIC chip, the output terminal of the ASIC chip is connected to the input terminal of the micro coil, and the micro coil is interactively connected to one end of the external portable reading device.
[0011] Preferably, the external portable reading device includes a radio frequency energy transmission and data reception module, a main control module, and a Bluetooth module; One end of the radio frequency energy transmitting and data receiving module is interactively connected to one end of the intelligent artificial lens, and the other end is connected to the input end of the main control module. The output end of the main control module is connected to the input end of the Bluetooth module; the output end of the Bluetooth module is connected to the user terminal.
[0012] Secondly, the present invention also provides a wireless method for acquiring intraocular pressure data, based on the aforementioned wireless intraocular pressure data acquisition system, comprising the following processes: The main control module determines whether to enter the patient active mode or the automatic scanning mode based on the preset strategy or user instructions, and initializes the communication parameters. The external portable reading device is activated, and a radio frequency energy field is established around the external portable reading device. When the intelligent intraocular lens enters the radio frequency energy field, the passive sensor module inside the intelligent intraocular lens obtains energy and is awakened. After being awakened, the passive sensor module performs intraocular pressure and temperature measurements, and performs temperature compensation correction on the original intraocular pressure reading to obtain the corrected intraocular pressure value. At the same time, it compares the current reading with historical readings. If it determines that the intraocular pressure is in a state of rapid fluctuation, it sends a high-frequency sampling request flag to the external portable reading device. The external portable reading device receives the corrected intraocular pressure data and the high-frequency sampling request flag, and executes a patterned response according to the mode entered by the main control module; The data after executing the standardized response is sent to the user terminal and uploaded to the cloud service platform, where it is analyzed and alerted.
[0013] Preferably, when in patient-active mode, the external portable reading device sends complete data to the user terminal via Bluetooth module; if a high-frequency sampling request is received, the user is prompted to keep the device in place, and the main control module controls the radio frequency energy transmission and data reception modules to perform multiple continuous excitations and readings within a preset time period to capture the rapid changes in intraocular pressure.
[0014] Preferably, when in automatic scanning mode, the external portable reading device automatically and briefly turns on the radio frequency field for listening with a low power cycle; if no valid sensor response is received, it remains in standby mode; if a response is received and the data is normal, a normal monitoring log is recorded; if a response is received and the intraocular pressure value exceeds a preset safety threshold, or a high-frequency sampling request is received, it switches to continuous working mode, completes full data reading, and initiates a local warning.
[0015] Preferably, the temperature compensation correction is performed in real time by the ASIC chip, using the acquired temperature data to compensate the original intraocular pressure reading online, so as to eliminate the influence of temperature drift on the accuracy of intraocular pressure measurement.
[0016] Preferably, the data after executing the patterned response includes intraocular pressure value, temperature value, timestamp, collection mode identifier, and contextual information at the time of collection, which are used by the cloud service platform for long-term trend analysis and graded early warning.
[0017] Preferably, the intelligent intraocular lens is a passive device, and the energy required for its operation comes from the radio frequency energy field established by the external portable reading device, without the need for an internal power supply.
[0018] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a wireless intraocular pressure (IOP) data acquisition system, constructing a four-layer collaborative architecture comprising an intelligent intraocular lens, an external portable reading device, a user terminal, and a cloud service platform. This system addresses the shortcomings of existing technologies at the system level. To address the issue of data partiality, the system integrates the dispersed acquisition, transmission, and analysis processes into a closed loop, providing hardware support for comprehensively capturing dynamic IOP data. To address electromechanical bottlenecks, its passive implant and external excitation design avoids the limitations of battery life and the risk of secondary surgery associated with built-in power supplies. To address rigid strategies, the system reserves expansion space for dual-mode adaptive acquisition and event-driven logic, allowing acquisition behavior to be dynamically adjusted according to physiological states. To address insufficient data quality, the multi-module collaborative architecture lays the foundation for source quality control and contextual information fusion, thus achieving a systemic breakthrough in long-term IOP monitoring in terms of data integrity, device reliability, intelligent acquisition, and data credibility.
[0019] Furthermore, by integrating the passive sensor module into the optical part and the root of the support haptic module of the intelligent intraocular lens, the intraocular pressure monitoring function is integrated without affecting the original optical function and biocompatibility of the intraocular lens. This reduces the complexity and trauma risk of the implantation surgery and provides a hardware foundation for passive collaborative acquisition.
[0020] Furthermore, through the integrated design of pressure sensors, ASIC chips, micro coils, and temperature sensors, the sensor module is equipped with the ability to simultaneously acquire intraocular pressure and temperature, perform real-time temperature compensation, and transmit wirelessly. This improves data accuracy and reliability from the signal source, providing high-quality data support for subsequent adaptive sampling and intelligent analysis.
[0021] Furthermore, through the coordinated operation of the radio frequency energy transmission and data reception module, the main control module, and the Bluetooth module, wireless energy supply and data reading from the implant by the external device are realized. At the same time, convenient communication with the user terminal is supported, providing a hardware control foundation for the implementation of the dual-mode acquisition strategy and ensuring the user-friendliness and operability of the system.
[0022] This invention also provides a wireless method for acquiring intraocular pressure data. This passive collaborative acquisition method completely eliminates the battery life limitations and risks of secondary surgery associated with built-in power supplies, while avoiding the biosafety hazards of active radiofrequency heating. By combining patient-active mode and automatic scanning mode, it ensures data quality during user-initiated participation while enabling hands-free background monitoring, significantly improving the probability of capturing transient intraocular pressure spikes during critical periods such as nighttime and emotional fluctuations. This method is not merely a partial optimization of existing technology, but rather a system-level innovation that simultaneously overcomes traditional technical bottlenecks in four dimensions: data integrity, device reliability, intelligent acquisition, and data credibility. It provides a solution for the long-term management of glaucoma that combines accuracy and safety.
[0023] Furthermore, through the high-frequency sampling response mechanism in the patient-active mode, short-term continuous acquisition is automatically triggered when intraocular pressure fluctuates rapidly, enabling the system to accurately capture key stages of pathophysiological changes, optimizing the information density and clinical value of data acquisition, while ensuring the flexibility and data quality when users actively participate in monitoring.
[0024] Furthermore, by using low-power listening and abnormal triggering logic in automatic scanning mode, proactive background monitoring without patient intervention is achieved, greatly reducing the requirements for user compliance. At the same time, timely activation of complete data collection and local alerts in case of abnormalities effectively improves the probability of capturing key data during non-active periods such as nighttime, thereby enhancing the security and reliability of the system.
[0025] Furthermore, by performing temperature compensation correction in real time through the ASIC chip, the impact of temperature drift on the accuracy of intraocular pressure measurement is eliminated at the front end of the signal chain, ensuring data quality from the source, avoiding interference from original data errors on subsequent analysis and diagnosis, and improving the credibility and usability of clinical data.
[0026] Furthermore, by collecting standardized data packets containing intraocular pressure values, temperature values, timestamps, collection mode identifiers, and contextual information, rich contextual information is provided for long-term trend analysis and graded early warning in the cloud, making data interpretation more targeted and accurate, and enhancing the clinical application value of the system.
[0027] Furthermore, through the passive design of the intelligent intraocular lens, its working energy comes entirely from the external radiofrequency energy field, eliminating the need for a built-in power supply. This fundamentally eliminates the risk of power replacement during secondary surgery and the biosafety hazards of active radiofrequency heating, achieving long-term reliable monitoring with the same lifespan as the intraocular lens, and significantly improving patient safety and quality of life.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0030] The purpose of this invention is to provide a wireless acquisition system and method for intraocular pressure data, so as to solve the technical problems of data partiality, electromechanical bottleneck, rigid strategy and insufficient quality in the long-term intraocular pressure monitoring of existing data acquisition technologies.
[0031] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1 See Figure 1 In one embodiment of the present invention, a wireless acquisition system for intraocular pressure data is provided, including an intelligent intraocular lens 100, an external portable reading device 200, a user terminal 300, and a cloud service platform 400; one end of the intelligent intraocular lens 100 is interactively connected to one end of the external portable reading device 200, the other end of the external portable reading device 200 is interactively connected to one end of the user terminal 300, and the other end of the user terminal 300 is interactively connected to the cloud service platform 400.
[0032] Specifically, the intelligent intraocular lens 100 includes a passive sensor module 110, an optical section, and a support haptic module 120; the passive sensor module 110 is integrated at the root of the optical section and the support haptic module 120; the passive sensor module 110 is interactively connected to an external portable reading device 200.
[0033] The passive sensor module 110 includes a pressure sensor 111, an ASIC chip 112, a micro coil 113, and a temperature sensor 114. The output terminals of the pressure sensor 111 and the temperature sensor 114 are connected to the input terminal of the ASIC chip 112, the output terminal of the ASIC chip 112 is connected to the input terminal of the micro coil 113, and the micro coil 113 is interactively connected to one end of the external portable reading device 200.
[0034] In this embodiment, the detailed features of the passive sensor module 110 are as follows: The core sensor is a MEMS capacitive pressure sensor used to sense intraocular pressure. It does not have its own independent power source, such as a battery.
[0035] Application-Specific Integrated Circuit: Includes ASIC chip 112, which integrates a capacitor-to-digital converter, micro memory, and control logic.
[0036] Energy receiving and data communication unit: a miniature coil 113, used to receive radio frequency energy and backscatter modulated data externally.
[0037] Auxiliary sensor: Integrated with temperature sensor 114 for real-time monitoring of sensor chip temperature.
[0038] Encapsulation: The entire module is sealed with a biocompatible material (such as phenelzine) to isolate it from the intraocular environment.
[0039] Function and principle: The lens serves as the data source. Its passive sensor module 110 is only activated momentarily after receiving specific external radio frequency energy excitation, completing the sensing, analog-to-digital conversion and data storage of intraocular pressure and temperature, and transmitting the data through load modulation technology.
[0040] Specifically, the external portable reading device 200 includes a radio frequency energy transmission and data reception module 210, a main control module 220, and a Bluetooth module 230; one end of the radio frequency energy transmission and data reception module 210 is interactively connected to one end of the intelligent artificial lens 100, and the other end is connected to the input end of the main control module 220, and the output end of the main control module 220 is connected to the input end of the Bluetooth module 230; the output end of the Bluetooth module 230 is connected to the user terminal 300.
[0041] In this embodiment, the external portable reading device 200 is the excitation and control center for data acquisition. It is responsible for generating and transmitting a radio frequency energy field of a specific frequency (e.g., 13.56MHz) to power the passive sensor module 110; at the same time, it receives the modulation signal backscattered from the sensor and decodes the raw data of intraocular pressure and temperature; its main control module 220 executes the core dual-mode acquisition strategy and adaptive sampling logic of this invention.
[0042] In this embodiment, the user terminal 300 (such as a smartphone app) is responsible for receiving data from the external portable reading device 200 and uploading it to the cloud service platform 400. The cloud service platform 400 is responsible for storing the data, performing in-depth analysis (such as trend judgment and early warning calculation), and feeding back the results or early warnings to the user terminal 300 and the doctor's terminal.
[0043] In summary, this invention provides a wireless intraocular pressure (IOP) data acquisition system, constructing a four-layer collaborative architecture comprising an intelligent intraocular lens, an external portable reading device, a user terminal, and a cloud service platform. This system addresses the shortcomings of existing technologies at the system level. To address the issue of data partiality, the system integrates the dispersed acquisition, transmission, and analysis processes into a closed loop, providing hardware support for comprehensively capturing dynamic IOP data. To address electromechanical bottlenecks, its passive implant and external excitation design avoid the battery life limitations and secondary surgical risks associated with built-in power supplies. To address rigid strategies, the system reserves expansion space for dual-mode adaptive acquisition and event-driven logic, allowing acquisition behavior to be dynamically adjusted according to physiological states. To address insufficient data quality, the multi-module collaborative architecture lays the foundation for source quality control and contextual information fusion, thus achieving a systemic breakthrough in long-term IOP monitoring in terms of data integrity, device reliability, intelligent acquisition, and data credibility.
[0044] Example 2 according to Figure 2As shown, this embodiment also provides a wireless method for acquiring intraocular pressure data. Based on the aforementioned wireless intraocular pressure data acquisition system, the method includes the following steps: Step S101: Mode Selection and Initialization The main control module 220 determines whether to enter the patient active mode or the automatic scanning mode according to the preset strategy or user instructions, and initializes the communication parameters.
[0045] Step S102: Establishment of radio frequency energy field and sensor wake-up The radio frequency energy transmitting and data receiving module 210 is activated, establishing a stable radio frequency energy field around the device. When the smart lens 100 enters the effective range of this field (e.g., 0-5cm), its passive sensor module 110 receives energy and is awakened.
[0046] Step S103: Collaborative Data Acquisition and Preprocessing The awakened passive sensor module 110 immediately performs a high-precision intraocular pressure and temperature measurement. After completing the analog-to-digital conversion, the ASIC chip 112 calls the built-in temperature compensation algorithm in real time to correct the original intraocular pressure reading using the temperature data collected this time (from the temperature sensor 114), and obtains a high-quality corrected intraocular pressure value, which is then temporarily stored in the micro memory.
[0047] In this embodiment, the ASIC chip 112 compares the current reading with the temporarily stored historical readings. If it determines that the intraocular pressure is in a state of rapid fluctuation (such as the rate of change per unit time exceeding a threshold), it will send a "high-frequency sampling request" flag to the external portable reading device 200.
[0048] Step S104: Data Reading and Patterned Response The external portable reading device 200 receives corrected intraocular pressure data and a possible "high-frequency sampling request" flag from the passive sensor module 110.
[0049] The modes selected in this embodiment include "patient-active modular mode" and "automatic scanning mode": If in "patient-active mode": the device will send complete data to the user terminal 300 via Bluetooth to complete one acquisition. If a "high-frequency sampling request" is received, the user will be prompted to keep the device in place. The main control module 220 will immediately control the radio frequency energy transmission and data reception module 210 to perform multiple continuous excitations and reads within a short period of time (such as the next minute) to capture the rapidly changing process.
[0050] In "Automatic Scanning Mode": The device automatically and briefly (e.g., 0.1 seconds) activates the radio frequency field for "listening" at low-power intervals (e.g., per hour). If no valid sensor response is received, it remains in standby mode, greatly saving power. If a response is received and the data is normal, only a "Monitoring Normal" log is recorded. Only when a response is received and the intraocular pressure value exceeds a preset safety threshold, or when a "High-Frequency Sampling Request" is received, will the device switch to continuous operation, complete the full data reading, and initiate an immediate local alert (e.g., device vibration).
[0051] Step S105: Data upload, analysis, and management closed loop The external portable reading device 200 sends the complete dataset (including intraocular pressure, temperature, timestamp, acquisition mode identifier, etc.) to the user terminal 300 and uploads it to the cloud service platform 400.
[0052] The cloud service platform 400 further analyzes long-term trends and combines contextual information such as data collection pattern identifiers to execute more complex early warning logic. Ultimately, users and doctors can view continuous, high-quality intraocular pressure curve reports through their terminals and receive tiered alerts when abnormalities occur.
[0053] This embodiment proposes a dual-mode acquisition strategy combining a "patient-active mode" and an "automatic scanning mode." The "patient-active mode" ensures high-quality data acquisition while the user is actively engaged; the "automatic scanning mode" is a revolutionary supplement, actively detecting intraocular pressure (IOP) by automatically performing brief radio frequency listening in the background at low power intervals (e.g., hourly) without any patient intervention. Once an abnormal signal is detected during a preset non-active period (e.g., at night), the system immediately triggers a complete recording. This method transforms traditional "passive response" acquisition into "active detection" acquisition, significantly increasing the probability of capturing transient IOP spikes, thereby obtaining a more realistic and comprehensive dynamic IOP map.
[0054] To address the limited lifespan, secondary surgery risks, and active radiofrequency heating issues inherent in standalone implantable devices due to their built-in power supplies, this invention employs a collaborative acquisition mode combining a "passive implant" and "external excitation." The sensor module of the implant itself contains no battery; its operating power is entirely provided wirelessly via radiofrequency field by the external reading device when needed. This design offers fundamental advantages: Unlimited lifespan: The implant itself has no consumable limitations and theoretically has the same lifespan working potential as an artificial lens.
[0055] Eliminating thermal damage: The system only performs short-duration, weak radio frequency communication at the moment of acquisition, avoiding the continuous heat generation risk caused by the long-term, periodic active transmission of traditional equipment, resulting in extremely high biosafety.
[0056] On-demand operation: It achieves the ideal state of "silent standby and wake-up on demand", optimizing energy efficiency from a physical principle.
[0057] To address the energy consumption and data redundancy caused by fixed sampling strategies, this invention incorporates "event-driven" and "adaptive sampling" logic into the method. The system does not mechanically execute acquisition commands. In "automatic scanning mode," the complete process is only initiated when an abnormality is detected. More importantly, in either mode, the ASIC chip 112 can send a "high-frequency sampling request" flag to the external device based on the real-time intraocular pressure change rate (e.g., determining whether it is in a "rapid fluctuation state"). The main control module 220 responds to this flag and immediately initiates short-term high-frequency continuous acquisition. This method of "adaptively adjusting the acquisition strategy based on physiological signal characteristics" allows system resources (energy, bandwidth, storage) to be concentrated on capturing the most valuable pathophysiological changes, achieving higher data "information density" and clinical value with the same resources.
[0058] To address the issues of raw data being susceptible to interference and lacking context, this invention innovatively embeds multi-source data fusion and real-time preprocessing into the acquisition process. At the moment of each acquisition wake-up, the passive sensor module 110 not only acquires intraocular pressure (IOP) data but also simultaneously acquires data from the temperature sensor 114. The dedicated ASIC chip 112 then executes a real-time temperature compensation algorithm before data transmission to correct the raw IOP reading. This step eliminates a major source of error at the very beginning of the signal chain. Simultaneously, the acquisition process records contextual information such as timestamps and acquisition mode identifiers. Thus, the system output is no longer a raw, isolated "reading," but a "standardized data package" that has undergone preliminary quality control and is rich in context, providing a high-quality, directly usable data foundation for subsequent cloud-based in-depth analysis and clinical diagnosis.
[0059] In summary, this invention is not a simple improvement on existing components, but rather a completely new, system-level "working logic" and "control method" for intraocular pressure data acquisition. This method, through the organic combination of four innovative elements—"dual-mode triggering," "passive collaboration," "intelligent adaptation," and "source quality control"—systematically overcomes the traditional challenges of long-term continuous intraocular pressure monitoring in terms of data integrity, equipment reliability, intelligent acquisition, and data credibility, providing an excellent solution that balances clinical precision needs with a user-friendly experience.
[0060] This embodiment designs a collaborative acquisition method that combines "dual-mode driving" and "adaptive response" under intelligent control by an external device, and links it with a passive implant that integrates auxiliary sensors and preprocessing capabilities. This successfully achieves high-quality, clinically relevant continuous intraocular pressure data streams while ensuring long-term safety and extremely low implant power consumption.
[0061] In summary, this invention also provides a wireless method for acquiring intraocular pressure data. Passive collaborative acquisition completely eliminates the battery life limitations and risks of secondary surgery associated with built-in power supplies, while avoiding the biosafety hazards of active radiofrequency heating. By combining patient-active mode and automatic scanning mode, it ensures data quality during user-initiated participation while enabling hands-free background monitoring, significantly improving the probability of capturing transient intraocular pressure spikes during critical periods such as nighttime and emotional fluctuations. This method is not merely a partial optimization of existing technologies, but rather a system-level innovation that simultaneously overcomes traditional technological bottlenecks in four dimensions: data integrity, device reliability, intelligent acquisition, and data credibility. It provides a solution for the long-term management of glaucoma that combines accuracy and safety.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it.
