TowardPi Medical Showcases Full-Spectrum Innovation from Diagnosis to Treatment at CCOS 2025

The Symposium was organized byFudan University Eye, Ear, Nose and Throat HospitalProfessor Gézhì Xú、Xi'an People's Hospital(Xi'an No.4 Hospital)Professor Hong YanCo-chair,Professor Weiwei Yu from Peking Union Medical College Hospital, Chinese Academy of Medical SciencesZheProfessor Xu Wen from the Second Affiliated Hospital of Jiang University School of MedicineConduct academic sharing, and delve into the clinical value and development trends of swept-source OCT technology.

SpeakerProfessor Yu WeihongBy technical comparison, it was pointed out that intraoperative SS-OCT has achieved a breakthrough in clinical usability compared to traditional intraoperative OCT. In the past, intraoperative OCT imaging signals were easily interfered with by media such as dyes, gases, and blood cells, making it impossible to use stably throughout the procedure.TowardPi Surgical MicroscopeThe SS-OCT implemented during the operation has achieved two major innovations: first, the wavelength has been increased from the traditional 840-870nm to 1060nm.Significantly Enhanced Penetration Capability; Second, the frequency domain technology was upgraded to swept-source technology, which not only improved real-time performance but also achieved an ultra-large depth of field of 12mm. These two innovations have enhanced intraoperative OCT.Truly Achieve"Full-process availability" empowers doctors to make precise decisions at any time.. At present, the intraoperative SS-OCTA technology can preliminarily display large non-perfused areas of the retina and neovascularization, providing crucial decision support for surgeries related to retinal vascular diseases. Speaking about the development of TowardPi's technology, Professor Yu could not hide his excitement: "It happens to coincide with...September 3rd Parade, Xiehe and China in the same frame, looking forward to the accelerated development of domestically produced ophthalmic equipment, contributing to the enhancement of national medical strength."

SpeakerProfessor Wen XuSystematically expounded the five core advantages of intraoperative SS-OCT for anterior segment surgery: First, it provides richer imaging information than traditional microscopes; Second, it has good penetration for corneal opacity surgeries, supporting the execution of complex procedures; Third, it clearly displays the complete picture of the lens and the structural relationships of the surrounding anterior segment tissues, facilitating timely identification of abnormalities; Fourth, it accurately distinguishes membranous tissues, providing real-time safety warnings during surgery; Fifth, it offers real-time decision-making support in complex surgeries, truly achieving "intraoperative decision-making." She particularly noted that the development of intraoperative SS-OCT technology has transformed OCT from a simple preoperative examination device into...Key Tool for Solving Complex Surgical Challenges, helping many patients who previously had difficulty accessing treatment regain their sight. At the same time, this technology is of great guiding significance for young doctors learning traumatic cataract surgery and establishing a surgical quality evaluation system. TowardPi's intraoperative SS-OCT microscope is precisely..."Driven by Life"A vivid embodiment of continuous innovation.

HostProfessor XU GezhiPointed out: The potential value of intraoperative OCT technology has not been fully utilized, and this conference focuses onIntraoperativeOCTAIt is an important breakthrough for high-end surgical microscopes. As the host who has not yet personally experienced this technology, along with the colleagues present, we all have high expectations for this innovative technology that can capture retinal blood flow signals in real time during surgery and provide dynamic navigation — how it achieves the upgrade from "seeing" to "clearly seeing," and how it will assist surgeons in accurately assessing proliferative membranes and evaluating blood perfusion, promoting surgical decision-making to shift from "experience-dependent" to "image-guided"!

HostProfessor Hong YanEvaluating from the perspective of clinical practical experience: TowardPi's intraoperative swept-source OCT surgical microscope has achieved a generational leap from "spectral-domain" to "swept-source," bringingImported equipment not yet fully availableA completely new experience. Among them, the real-time synchronization technology of scanning range and microscope depth of field stands out —— where the doctor observes under the microscope, the imaging range of the swept-source OCT automatically covers.Without the need to repeatedly interrupt surgery and manually adjust the scanning position, as is required with traditional imported equipment., significantly enhancing the continuity of the surgical process and reducing additional intraoperative time consumption. The real-time precise measurement function is also an important breakthrough. Professor Yan Hong particularly emphasized the revolutionary role of this technology in clinical teaching: "Tutors can rely on real-time imaging and data to intuitively explain to students 'why the lens position needs to be adjusted at this moment' and 'what constitutes an ideal fitting state,' allowing students to no longer simply imitate the 'sense of touch,' but instead understand surgical standards and operational basis through real, objective images, thereby mastering the precise implantation technique more quickly and effectively shorteningLearning cycle."

The seminar showcased some of the clinical application achievements of TowardPi's swept-source OCT technology during surgery, such as its high penetration power, ultra-large scanning range, and real-time synchronization features supported by its high-speed swept-source technology. These are the foundations for redefining real-time decision-making in ophthalmic surgery, making surgeries more precise, safer, and more efficient, while providing a new tool for clinical teaching and helping to improve the level of ophthalmic care in China.

The microscopic world of ophthalmic surgery, where every micrometer of operation can impact the patient's world of light. The application of Swept-Source intraoperative OCT (SS-iOCT) technology is reshaping the decision-making models and operational standards in ophthalmic surgery. The symposium was hosted byProfessor Hong Jing from Peking University Third Hospital, Professor Zhang Han from Shandong First Medical University Affiliated Provincial HospitalCo-chair,Dr. Lu Yao from Peking University Third Hospital、Dr. Xu Zhe from the Second Affiliated Hospital of Zhejiang University School of Medicine, Dr. Liu Bosh from Tianjin Medical University Eye Hospital, Dr. Peng Rongmei from Peking University Third Hospital,Multiple experts shared via surgical videos, further elaborating on the significance and clinical application value of this technology.

SpeakerDr. Lu YaoFocusing on the surgical application of proliferative diabetic retinopathy (PDR), it was noted that vitreous management in PDR is more complex compared to other surgeries, often accompanied by multiple neovascularizations and proliferative membranes, making the selection of surgical entry points more challenging. Intraoperative SS-OCT provides better planning, technical guidance, and detailed control for these complex surgeries, especially when managing diabetic retinopathy cases without posterior vitreous detachment or retinal photocoagulation, significantly reducing decision-making difficulty and enabling real-time precision decision-making during surgery.

SpeakerDr. Xu ZheShared the Application Value of SS-iOCT System in Traumatic Cataract Surgery. Traumatic cataract surgery is complex, uncertain, and high-risk, essentially constituting an ocular reconstruction procedure. Traditional microscopic surgery often encounters limited observation range due to corneal or iris abnormalities and insufficient evaluation of the lens and capsular support system. In contrast, the SS-iOCT system dynamically and in real-time presents cross-sectional information of the entire anterior segment, addressing deficiencies in preoperative assessment from multiple dimensions. It supports surgeons in timely adjusting surgical plans, thereby significantly reducing complications and enhancing safety alerts.

SpeakerDr. Liu Bosh"Tracing the Fundus, Who Holds the Light?" Highlighting the use of SS-OCT during surgery, which enables non-invasive fundus examination for patients who could not be assessed preoperatively, assisting doctors in deciding whether to inject drugs and greatly simplifying the surgical process. "Technological advancements are gradually rewriting traditional medical practices, continuously improving healthcare efficiency." TowardPi's intraoperative SS-OCT navigation microscope truly realizes intelligent operation during the surgical process.

SpeakerDr. Peng RongmeiInsights were shared from the perspective of corneal surgery, pointing out that corneal surgeries involving the posterior elastic layer are extremely difficult and demand highly precise techniques. "Chinese surgeons already have an advantage in surgical operations, and the addition of SS-OCT real-time navigation during procedures further enhances their capabilities, enabling micron-level precision and significantly improving the success rate of surgeries."

HostProfessor Hong JingCorneal transplantation has entered the era of precise component corneal transplantation, allowing for refined transplantation at different layers. She emphasized that endothelial surgery places extremely high demands on microscopes — after membrane peeling, the membrane tends to curl into a tube shape, making it difficult to distinguish the front from the back under a traditional microscope. However, the application of intraoperative OCT has completely resolved this issue, making the orientation of the membrane clearly visible and significantly reducing surgical risks. Professor Hong believes that with the market promotion of this technology, corneal transplantation will become more widely available in hospitals across China, benefiting more patients.

HostProfessor Zhang HanTraditional surgery is considered a "single-view" operation, making it difficult for the surgeon to detect potential risks in front of or behind the microscope’s field of view; however, the emergence of swept-source intraoperative OCT has broken this limitation, allowing doctors to directly visualize previously inaccessible areas. This enables them to perform surgeries with greater ease, boldness, and precision. It was also emphasized that this technology has brought revolutionary changes to clinical teaching, allowing young doctors to directly observe surgical details and outcomes, rapidly accumulate experience, and build confidence.

The exchange meeting fully demonstrated the core value of swept-source OCT technology in ophthalmic surgery, with related activities carried out simultaneously.Surgical Live StreamingIt also objectively demonstrates the practicality, reliability, and stability in clinical applications. From the cornea to the retina, from routine surgeries to complex cases, this technology is reshaping the decision-making pathways and operational standards of ophthalmic surgeries, aiming to ensure every step is evidence-based and every moment is controllable. As the conference theme "Illuminate the Future with Light, Define the World with Shadows" implies, the swept-source intraoperative OCT technology is lighting the way forward for ophthalmic surgeries and building a solid foundation for patients' bright world.

The symposium was organized byProfessor Han Quanhong from Tianjin Eye Hospital、Professor Jiang Bing from the Second Xiangya Hospital of Central South UniversityCo-hosted by,Professor Tao Li from Zhongshan Ophthalmic Center, Sun Yat-sen University,Professor Yun'e Zhao from Hangzhou Branch of Eye Hospital, Wenzhou Medical UniversityGather together to delve into the clinical applications and development trends of multimodal technology in ophthalmology.

SpeakerProfessor Li TaoIt was pointed out that different imaging modalities in ophthalmology each have unique value and cannot completely replace one another. Therefore, multi-modal combined diagnosis remains the inevitable choice for precise diagnosis. Today, TowardPi has achieved multi-modal integration of 133° four-band colorful fundus photography, autofluorescence, red-free imaging, IR imaging, FFA, ICGA, and OCT&OCTA with a maximum range of 30×25mm (approximately 150° of the intraocular angle). Moreover, this integration is not a simple arrangement of images but enables imaging at any position.Precision Point-to-Point Linkage Analysis, leading the comprehensive entry into multi-modal joint analysis in ophthalmology"Ultra-Wide Angle, Big Data, Multi-Modality, Point-to-Point Integration"The multi-modal 2.0 era marks a milestone in the development of precise ophthalmic multi-modal diagnosis and treatment. The core advantage of TowardPi's new ultra-widefield four-wavelength confocal laser imaging technology lies in its "extremely high sensitivity to minute lesions" — it can capture subtle changes in retinal structures more sensitively and three-dimensionally, helping doctors identify "hidden lesions" that are difficult to detect with optical fundus photography.

SpeakerProfessor Yun'e ZhaoRegarding the special group of patients with high myopia combined with cataracts, it was pointed out that the accuracy of traditional refractive prediction still faces many challenges. A comparison of the biometric parameters between TowardPi's new-generation swept-source optical biometer "Meridian" and IOLMaster 700 showed good consistency in multiple core parameters, providing strong support for cross-validation in clinical measurements and equipment interchangeability. Professor Zhao Yune emphasized that swept-source OCT, with its technical advantage of segmented optical deconstruction, enables fine parsing of intraocular structures (i.e., segmented axial length model measurement), "which theoretically lays the foundation for higher measurement accuracy; in the future, more high-quality clinical data will be needed to further optimize the calculation formula for intraocular lens power, ultimately improving the visual quality and refractive satisfaction of patients with high myopia after cataract surgery."

HostProfessor Han QuanhongHighly recognized the necessity of multimodal joint analysis for precise ophthalmic diagnosis and treatment, praised the innovative breakthroughs achieved by TowardPi's ultra-widefield big data multimodal point-to-point joint analysis in advancing the understanding and comprehensive recognition of ophthalmic diseases. Meanwhile, it pointed out that using ultra-widefield multicolor imaging as a guide, combined with modalities such as OCT and OCTA, has broad prospects in reducing lesion misdiagnosis, improving the level of precise diagnosis and treatment, and deepening disease research.

HostProfessor Jiang BingTowardPi "Ziwu" Swept-Source Optical Biometer Shows Good Consistency in Core Parameters with IOLMaster 700, and Ziwu’s Segmented Optical Deconstruction Technology Enables Axial Segmentation Model Measurement, Theoretically Ensuring Higher Measurement Accuracy; Refractive Prediction for High Myopia Patients with Cataract Remains Challenging, Which Requires Further Optimization of Both Instrumentation and Intraocular Lens Calculation Formulas. The Ziwu Swept-Source Biometer Provides Precise Data Measurements to Help Optimize Intraocular Lens Formulas, Improving Postoperative Visual Quality and Refractive Satisfaction for Such Patients.

The symposium showcased TowardPi's multi-modal, digital, and intelligent joint diagnostic solutions. With the support of artificial intelligence technology, it will further enhance the diagnostic and triage capabilities and efficiency of ophthalmology in China, especially in grassroots hospitals, and improve the accessibility of high-quality medical care.
