9:24 AM PT -- Good news, bad news for Boychuck ...
The good ... Islanders GM Lou Lamoriello says the defenseman did NOT suffer damage to his eyeball in the accident.
The bad ... the injury took 90 stitches to repair!
"He felt the skate blade get his eye," Lamoriello said Wednesday morning. "But, fortunately, it just got the eyelid. It took 90 stitches to fix. A plastic surgeon took care of it."
Lou added, "He'll be fine. It's just a matter of time, with the eye opening up and him feeling good.
