Chinese doctors restore sight for 500 Sri Lankans

Three years ago, a cornea from Sri Lanka restored Xu Pengfei's sight in his right eye, and on Wednesday the 10-year-old was able to express his thanks by helping someone in Sri Lanka see again.

On Wednesday, Xu and a Chinese doctor together removed the bandages on the eyes of Sudarma Karunaratna, a 74-year-old English teacher, after she had cataract surgery on her right eye at a hospital in Colombo, capital of Sri Lanka.

Karunaratna is one of 500 patients who have received free surgeries from Chinese doctors in the past four days and recovered their eyesight.
