Dr. Weidong Yu takes a revolutionary step towards the treatment of Eye Disorders

In 1999, Dr. Weidong Yu  challenged himself to improve the severe eye condition of one of his patients who had been diagnosed with Retinitis Pigmentosa (RP), an eye disease deemed untreatable under Western Standards.

After a few sessions of acupuncture paired with a treatment of herbal medicine, his patient began to feel improvement in her vision field and night vision. 

This became a revolutionary step towards the treatment of Retinitis Pigmentosa. Since then, Dr. Weidong Yu has improved the vision of over 900 patients with Retinitis Pigmentosa and hundreds of patients with other eye disorders such as Macular Degeneration, Myopia, Presbyopia, and Dry Eye Disease.
