I did a google search and found a little more information. It seems that this is "old news". Following are excerpts from:

Twelve-year-old Hasnah Mohamed Meselmani produced razor-sharp glass crystals from her eyes, Share International reported at the end of 1996. Nabil Matraji, our correspondent in the Lebanon, contacted the Meselmani family to find out more about the amazing phenomenon, which lasted from
March till November 1996. A discussion with Hasnah confirmed that the unseen hand behind the crystal miracle was that of Maitreya. A report about the mysterious “white knight” follows.Commotion stirred the Arab world: a girl was making hard glass crystals, sharp enough to cut paper, appear from her eyes seven times a day without any apparent injury to herself - it had to be some kind of miracle. The 12-year-old Hasnah Mohamed Meselmani became the centre of attention. Religious authorities and scientists sought answers to the riddle.

It all began in March 1996. She was at school when she felt something strange in her left eye - her first piece of crystal, which, understandably, troubled her. Back home, she told her family what had happened and, while she was doing so, a second piece of crystal appeared in her eye. Her father took her to the city of Chtaura to see Dr Araji, an ophthalmologist. She stayed in his clinic for two weeks, and the crystals kept flowing out of her eye.
Dr Araji certified that the pieces were real crystals and said he had no scientific explanation of the phenomenon. It could only be understood, he thought, as an act of God. A few days later, Hasnah was told the same thing in another strange event.
“One night,” she told Nabil, “I was still awake when I heard someone tapping at the window. I got up, walked to the window and there I saw a man dressed in white. He was sitting on a white horse, he smiled at me and called me by name. He asked me if I would go outside to talk to him.” Hasnah went out through the front door.
There stood the “white knight”, as she calls him, waiting for her. He was dressed from head to foot in a white tunic, which also covered his head and face.
“The white knight” said she needn’t be afraid and he introduced himself to Hasnah as a “messenger from God”. A conversation developed between them about which Hasnah revealed no further details, apart from the fact that the white knight led her to understand that it was he who had been behind the crystal tears, and that all went according to God’s will. There was a witness to the conversation: Hasnah’s little brother had followed her outside, heard his sister speaking, but failed to see who she was talking to. “The white knight” visited her a few times again and gave her advice and various warnings. When Hasnah asked when the tears would stop the answer was: “When God wills.”

That Maitreya appeared dressed in white with his face covered at first is not without significance within the Muslim tradition: it is forbidden to show the faces or make images of holy people or divine envoys.
