Marussia test driver Maria de Villota has lost her right eye as result of an accident yesterday afternoon.
The 32-year-old crashed into a lorry while taking part in a testing session in Duxford, Cambridgeshire.
She was taken to Addenbrooke's Hospital in Cambridge, where she remains in a critical but stable condition.
"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 at Duxford Airfield yesterday," said Marussia team principal John Booth.
"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 that I must report that, due to the injuries she sustained, Maria has lost her right eye.
"Maria's care and the wellbeing of her family remain our priority at this time. Her family are at the hospital and we are doing everything possible to support them.
"We ask for everyone's patience and understanding with regard to updates on Maria's condition. We will provide further information when it is appropriate to do so and with consideration for her family."
De Villota is the daughter of former Spanish F1 racing driver Emilio de Villota.
