Doctors treating Michael Schumacher say that there has been a 'slight improvement' in his condition but warned that 'there is a long path ahead.'
Schumacher was injured while skiing in the French Alps on Sunday and has been in a critical condition in Grenoble hospital.
Doctors undertook a new scan on Schumacher late on Monday, which revealed a window of opportunity for a second operation, after doctors were surprised at his unexpected improvement.
Schumacher was subsequently operated on for two hours to remove another haematoma, which has helped reduced intercranial pressure.
Schumacher will be kept in an induced coma which will "last the time we judge to be necessary."
Doctors were unwilling to offer information on the German's recovery, insisting that he was still being evaluated on an hourly basis.
Schumacher remains in a critical condition and continues to suffer from brain haemorraging.
"We can't say he is out of danger but... we have gained a bit of time,'' said Dr Jean-Francois Payen. "The coming hours are crucial"
"The situation is slightly better over the last 24 hours, but we must be realistic," they added.
Schumacher's family remain at his bedside.
A further news conference will be held when doctors deem it necessary.
