Marussia test driver Maria De Villota has lost her right eye in the wake of yesterday's accident at Duxford Airfield.
The 32-year-old Spaniard is described as being in a "critical but stable" condition after undergoing considerable overnight surgery at Addenbrooke's Hospital in Cambridge.
Team principal John Booth said: "Maria emerged from theatre at Addenbrooke's Hospital this morning after a lengthy operation to address the serious head and facial injuries she received in the accident.
"We are grateful for the medical attention that Maria has been receiving and her family would like to thank the neurological and plastics surgical teams.
"However, it is with great sadness I must report that, due to the injuries she sustained, Maria has lost her right eye."
