Elton John said he lost his eyesight and couldn't see the premiere of his new musical

• Elton John said he couldn't watch a performance of his new musical because he sight is still impaired.
• John wrote the music for "The Devil Wears Prada" stage musical, which is showing in London.
• In September, John said on Instagram that he had limited vision due to a severe eye infection.

Elton John said he was unable to watch the new "The Devil Wears Prada" musical in London because his vision is still impaired after an infection.

John shared the health update on Sunday while giving a speech after a special gala performance of the stage musical in support of his AIDS foundation, which was attended by celebrities like Anna Wintour, Donatella Versace and Lily Collins.

John composed the music for "The Devil Wears Prada" musical, based on 2006's "The Devil Wears Prada" movie, which is currently in the previews stage.

John said on Sunday that he hasn't attended many of the previews because he lost his eyesight.

"It's hard for me to see it but I love to hear it and boy it sounded good tonight," John said.

John also thanked his husband David Furnish, who helped John on and off stage, for being his "rock."

John first posted a statement on Instagram in September saying he only had limited eyesight following a severe eye infection.

"I am healing, but it's an extremely slow process and it will take some time before sight returns to the impacted eye," the statement read.

Last week, John told ABC's "Good Morning America" that he got the infection in his right eye in the South of France in July, and that his left eye did not have great vision either.

He said that he has been unable to finish his next album because of the vision problems.

"I'm kind of stuck at the moment, because I can do something like this, but going into the studio and recording, I don't know, because I can't see a lyric for a start," He said. "It kind of floored me. And I can't see anything, I can't read anything, can't watch anything."
