High-end Ophthalmic Medical Device Developer
Recently, Professor Yu Weihong, Director of the Ophthalmology Department of Peking Union Medical College Hospital, usedTowardPi Medical Intraoperative Swept-SourceOCT Navigation Surgical Microscope,For the first timeSuccessfully obtained the patient'sIntraoperativeFundusOCTA Image。
Case 1: Epiretinal Membrane

(a)IntraoperativeSS-OCTA Imaging
(SS-OCT is not affected by dyes)


(b) Pre-membrane peeling intraoperative OCTA image (left image)
(c) Intraoperative OCTA image after membrane peeling(Right Image)


(d) En face image before intraoperative membrane peeling(Left Figure)
Intraoperative OCTA showed no significant changes in blood flow, and en face structural images revealed the release of traction with the disappearance of retinal folds.
Case 2: Vitreous Traction

(b) Perform OCTA scan, no significant blood flow signal was found (at the location of the red arrow); cutting can be performed.
TowardPi's intraoperative swept-source OCT navigation surgical microscope, exclusively equipped with a 400,000 times/second swept laser light source and a self-developed ultra-high-speed data acquisition card, has once again led the development of intraoperative imaging technology after achieving stable, real-time, full-field high-definition OCT tomography, measurement, and 3D reconstruction for the first time during surgery.For the first timeIn a real clinical environmentAchieveOperationInSweep FrequencyOCTA(SS-iOCTA)ImagingCollection。
The emergence of this new technology showcases TowardPi's technical depth and innovative leadership in the fields of ophthalmic OCT and microscopic optics. It provides entirely new observable content for ophthalmic surgeries, offers more objective bases for intraoperative judgment and decision-making, making ophthalmic surgeries more reliable, precise, and safer. TowardPi will continue to adhere to independent and controllable principles, persistently achieve R&D breakthroughs, provide novel research tools for scientific exploration, and offer new support for China's ophthalmology to achieve academic leadership.
Technological Innovation, Ingenious Craftsmanship!
