De Bruyne was at the receiving end of a heavy challenge from Chelsea defender Antonio Rudiger in last weekend’s Champions League final that left the Manchester City man with a fractured nose and left eye socket.
De Bruyne’s participation in EURO 2020 was thrown into doubt in the aftermath of the collision especially when he was substituted straight after.
The 29-year-old has undergone a minor surgery and has been cleared to take his place in the Belgium squad, although he will miss their opening game of the competition.
"After looking at the images, it was decided Kevin needed a little bit of an intervention and that has taken place today, everything went really well, really positive, so we're looking forward to Kevin joining us on Monday, and he will join the squad for the Euros," Martinez told a news conference on Saturday.
Elaborating more on the surgery, Martinez added: "I'm not the right person to talk in medical terms, it was just necessary for the long-term structure of the eye socket.
"It wasn't the type of surgery that is for the full structure of the front of the bone, it was just to make sure in the long-term there are no issues, but it is not a surgery as such that he needs a long time recovery, it was just to make sure the area was stronger, it took 20 minutes, went really well and the medical department are really happy.
"He's really good, he's in good spirits and can't wait to get on the pitch. This is not a surgery that stops you getting back in activities, it is the opposite, it gives you the opportunity to not need protection to play, so that's been really good news from that point of view and it's been done at the right time to see Kevin involved in the squad.
Belgium begin their EURO 2020 campaign on June 12 against Russia before facing Denmark and Finland in Group B.
