I’m sure you can use google as well as anyone else.
Try Gemma Di Giorgi. It’s instructive.
I did find a slightly different story though.
Last year I was invited to meet with Gemma di Giorgi, a middle-aged lady from Sicily who by the grace of God received a miracle from Padre Pio when he was still alive. At that time she was seven years old. She was born without the retina in her eyes and was totally blind. It is like having a camera but without a film in it. Her grandmother, a fervent believer, prayed a lot for a miracle. Having heard so much about Padre Pio she decided one day to take her daughter and visit Padre Pio to ask him for his prayers. So both of them took the train and on the way to Padre Pio, she was healed. She could see. The first thing she saw was the sea and a ship. Then she turned around and looked at her grandmother. Since then she is well known all over Italy and last year I had met her just after her visit to the Holy Father who recognized her and gave her a Rosary. In many of Padre Pio's books she is mentioned as one of his great miracles. The miracle is that she still has no retina and yet she can see. The doctors are all confounded...
When did she first gain her eyesight?
