Kevin De Bruyne underwent minor surgery on his eye socket on Saturday.
The expectation is that the Belgian international will recover faster as a result and may be able to play at the European Championship without a face-protective mask.
De Bruyne collided hard with defender Antonio Rüdiger during the Champions League final against Chelsea last week.
The Manchester City playmaker broke both his nose and his left eye socket.
Initially it was reported that De Bruyne would not be operated on, but the medical staff of Belgium came back to that.
Surgery is expected to speed up the recovery process.
"After the swelling went away, this was the right procedure," national coach Roberto Martínez said during a press conference on Saturday.
"He may now be able to play without protection."
Despite the intervention, which only took twenty minutes, De Bruyne will join the group on Monday as planned.
"He can't wait to get back on the field," said Martínez.
"It's also not an operation that you have to recover from for a long time."
Belgium starts the European Championship on June 12 in Saint Petersburg against Russia. The number three of the last World Cup will compete in group C against Denmark (June 17) and Finland (June 21).Keywords:
