At the 39th World Congress of Ophthalmology (WOC 2024) held in Vancouver, Canada, Professor Zhang Xiaoshan of Dongguan Huaxia Eye Hospital was invited to attend as a leader in cataract treatment and multifocal intraocular lens applications. He delivered a keynote speech in the "Fast Track Research Round - Cataract Discipline", making the voice of the Chinese ophthalmology community loud again.

The theme of Professor Zhang Xiaoshan's speech was "Angle kappa Positioning Technology of Regional Refractive Multifocal Intraocular Lens". The wonderful content aroused great interest among ophthalmologists and scholars around the world and was widely praised by international peers. This not only demonstrated the advancement and innovation of Chinese ophthalmic technology, but also promoted exchanges and cooperation in the international ophthalmology community, and demonstrated the important position of Chinese ophthalmology in the global ophthalmology community.

Challenges and innovations of pupil eccentricity

People's pupils are generally eccentric, and the direction and size of the eccentricity are not fixed. This makes it difficult to accurately control the visual quality of patients after multifocal intraocular lens implantation. Faced with complex and ever-changing challenges, Professor Zhang Xiaoshan, together with university professors and software engineers, developed an innovative "regional refractive multifocal intraocular lens angle kappa positioning technology" to tailor personalized treatment plans for each patient, successfully solving the problem of refractive multifocal intraocular lens positioning, with excellent clinical results and awarded an invention patent.

Angle kappa positioning technology for regional refractive multifocal intraocular lenses

Professor Zhang Xiaoshan found through literature research that better balancing the pupil's response to long-distance and short-distance light (DS/NS) after lens implantation will achieve better visual effects. The regional refractive multifocal intraocular lens is a special type of multifocal lens. Based on the principle of refraction, it has no diffraction rings and has the unique advantages of good long and short vision, high clarity, and high light energy utilization. There has always been controversy about how to find the best position to place the intraocular lens to avoid the influence of pupil deviation. Professor Zhang Xiaoshan found through literature research that better balancing the pupil's response to long-distance and short-distance light (DS/NS) after lens implantation is the key to solving the problem. The regional refractive multifocal intraocular lens Angle kappa positioning technology invented by Professor Zhang Xiaoshan can calculate the optimal implantation position and rotation angle of the intraocular lens through the kappa angle, so as to locate and accurately implant the intraocular lens at the limbus, and use the DS/NS calculation APP for post-implantation verification. Clinical studies have confirmed that patients can obtain good vision and visual quality after implantation with this technology.

Practical Exercise of Patented Technology

At the conference, Professor Zhang Xiaoshan not only conducted in-depth academic sharing, but also demonstrated to ophthalmologists and scholars around the world how to customize personalized surgical plans for patients through precise calculations of patented software through a series of carefully selected case analyses and practical exercises of patented technologies, thereby ensuring the optimal position of the intraocular lens and improving surgical results and patient satisfaction. In particular, for patients who were not suitable for multifocal lenses in the past due to large visual axis deviation (kappa angle), Professor Zhang Xiaoshan's patented technology successfully solved the pain points of clinical practice, providing more convenient and more complete technology for peers, and also bringing clearer vision to more patients.

Chinese Ophthalmology: Innovative Power from an International Perspective

Professor Zhang Xiaoshan's wonderful speech brought valuable experience and profound inspiration to the global ophthalmology community, which not only demonstrated his personal superb professional level, but also set a new milestone in the clinical application of regional refractive multifocal intraocular lenses. Professor Zhang Xiaoshan actively participated in and had in-depth exchanges at the international conference, and discussed the latest research progress and clinical experience in this field with international ophthalmology experts, contributing Chinese strength to the advancement of global ophthalmology diagnosis and treatment technology.

Looking to the future, China's ophthalmology community will continue to shine on the international stage and bring more Chinese wisdom to the global eye health industry. This is not only an affirmation of the past achievements of Professor Zhang Xiaoshan and Huaxia Eye Hospital Group in China's ophthalmology community, but also a confident outlook on the future development of ophthalmology.
