Rape victim Fiona Doyle has personally asked the Taoiseach to introduce minimum prison sentences for sex offenders.
She also told Enda Kenny in a one-on-one meeting that judges should be "sensitised" to cases like her own to ensure no one is let down by the justice system.
"I asked for minimum sentencing, especially for rape and assault," Ms Doyle said. "I asked for younger judges and for judges to be sensitised and trained in handling cases like my own.
"There were a few good notes being taken. I'm hoping something will be done."
Ms Doyle, from Bray, Co Wicklow, was raped by her father Patrick O'Brien once a week for a decade from the age of eight.
There was public outcry when the 72-year-old rapist walked free earlier this month. He had been handed a 12-year sentence with nine suspended, but was released on bail to await an appeal on the jail term.
But Mr Justice Paul Carney was later forced to reverse O'Brien's bail and apologised to Ms Doyle. He said it had been insensitive and inappropriate to release O'Brien, also from Bray, Co Wicklow. He is now serving three years behind bars.
Ms Doyle met Mr Kenny in Government Buildings where they talked for over an hour.
The mother-of-three said the Taoiseach promised to take all her requests on board.
"He actually wanted to know my story and some of the details and some of the court case," she added. "It was a bit emotional. I had to stop a few times."
