"Thanks to the Chinese doctors, I have hope of seeing again."His operation marked the 3,603rd procedure completed under a cataract blindness prevention project jointly launched by the GX Foundation, a Chinese non-profit and non-governmental organization registered in China's Hong Kong Special Administrative Region, as well as the Fujian Provincial Health Commission.According to a World Report on Vision published in 2019 by the World Health Organization, more than 2.2 billion people globally suffer from visual impairment or blindness. For at least one billion of them, these conditions were preventable or remain treatable. A lack of eye care resources, especially in low- and middle-income countries, remains one of the leading causes.In Senegal, where the healthcare system remains underdeveloped and high ultraviolet exposure in the tropical savannah contributes to cataract development, the situation is particularly pressing. Many patients miss the optimal window for treatment due to limited medical services.Patients queue up to establish medical records at the Regional Hospital Center of Fatick in Fatick, Senegal, May 2, 2025. (Xinhua/Si Yuan)Senegal's Minister of Health and Social Action Ibrahima Sy described blindness and visual disorders as major public health issues, noting that nearly 165,000 people in the country are blind and more than 550,000 suffer from visual impairments caused by cataracts, trachoma, glaucoma, and other conditions."The situation is more serious than we had imagined," said Zheng Hong, chief physician from the ophthalmology department of Sanming No. 1 Hospital, Fujian. A month earlier, she and four colleagues had traveled over 10,000 km to reach this West African country."We initially planned to perform about 10 operations a day," Zheng said. "But faced with so many longing eyes, we all agreed to extend our working hours and now perform over 20 surgeries daily."In the early hours of last Friday, the hospital corridors were jam-packed with patients from across the country. Local volunteers efficiently handled registrations and screenings.A patient undergoes a vision examination at the Regional Hospital Center of Fatick in Fatick, Senegal, May 2, 2025.

He had lived with blurry vision for years, unable to access surgical treatment."We conduct thorough screenings for every patient," explained Zhang Caihua, chief physician from the ophthalmology department of Sanming No. 2 Hospital, Fujian. "Once cataracts are diagnosed, we customize intraocular lenses to suit each individual's eye condition."In the screening room, Zhang, assisted by local doctors, used a keratometer and A/B-scan ophthalmologic ultrasound to collect patient data. "The patients are very cooperative during screening and surgery," she said while reviewing the day's registry. "When the bandages come off, some patients dance, others cry. That joy transcends all language barriers."Zhang Caihua (R), chief physician from the ophthalmology department of Sanming No. 2 Hospital, China's Fujian Province, receives a patient at the Regional Hospital Center of Fatick in Fatick, Senegal, May 2, 2025.

Whether it's patients who have been blind for 30 years or centenarians, the joy of regaining sight deeply symbolizes Sino-Senegalese friendship," said Leung.He added that after completing the mission in Fatick, the Foundation would continue its free operations in N'dioum in the Saint-Louis Region, northwestern Senegal.At the ceremony, Li Yan, minister counselor at the Chinese Embassy in Senegal, affirmed China's commitment to deepening humanitarian medical assistance to Senegal, delivering real and tangible benefits to the Senegalese people.
