An off-duty policeman stabbed between the eyes says he was "foolish" not to think an aggressive Melbourne home invader would attack him.
Jade Hunia was on bail when he broke into Senior Constable Daniel Yeoman's house at Wantirna South in November, fracturing the policeman's eye socket and damaging surrounding nerves.
The officer and his wife Shereen delivered victim impact statements to the County Court of Victoria on Tuesday, telling the court they were "different people" since the violent home invasion.
The Yeomans' two children, aged 11 and nine, were asleep in their bedrooms at the time.
Mrs Yeoman heard her dogs barking and then saw Hunia climbing the back stairs to her home before forcing his way in.
Mr Yeoman confronted Hunia in the kitchen, with the offender demanding the policeman's car keys before stabbing him in the forehead.
Hunia, now 20, took the keys and stole the family's $25,000 Hyundai, which they'd bought only days earlier.
He was captured on camera speeding through nearby suburbs before he crashed into a wall and was capsicum-sprayed by police.
Hunia still claims to have no memory of the evening after leaving a party at Glen Waverley drunk.
Mr Yeoman told the court he tried to reason with the then-teenager after waking to his wife screaming.
"I didn't think he would stab me. I was foolish to think that," he said.
It took some time before Snr Const Yeoman was able to return to work after spending a week in hospital.
Mrs Yeoman cried while delivering her victim impact statement, saying "it was the scariest night of my life".
She has been diagnosed with post traumatic stress disorder.
Hunia's lawyer said he suffered post traumatic stress disorder after witnessing his sister's suicide in 2015 and on the night "didn't care about himself anymore; he didn't care about anything".
Judge Mark Dean described the offending as serious and "a shocking set of circumstances that's had a terrible effect" on the Yeomans.
He ordered a psychiatric report into Hunia's mental state before a further plea hearing on September 22.
