Krishnan Karunakaran had slashed throat of his 38-year-old wife Boomichelvi Ramasamy in October 2013 after she rebuffed his demands to help him stay in Singapore by getting his visa extended and not let him see their one-year-old daughter.
In his mitigation, Krishnan claimed that they separated after his wife had an affair, reported The Straits Times.
Deputy Public Prosecutor Mohamed Faizal took issue with the "false narrative" and rejected the assertion that the separation was victim's fault.
In sentencing Krishnan, Justice Chan Seng Onn said-- "There's no reason for you to resort to such violence, even if you desperately wanted to see your daughter. You should have resorted to the legal process and not take matters into your own hands.

"You are lucky that she survived, or you would be facing a far more serious charge," Justice Chan told Krishnan.
On the morning of Oct 27, 2013, Krishnan waited for his wife at the lift lobby of her apartment block in the Hougang housing estate.
He then made her walk towards her flat before slashing her throat in front of her nine-year-old daughter from a previous marriage and her maid.
The domestic helper opened the gate to help her bleeding employer while her daughter called the police.
Krishnan had pleaded guilty on Tuesday (on November 1) to one charge of attempted culpable homicide and one charge of criminal intimidation. Two other charges - for trying to stab Boomichelvi's abdomen and for threatening her domestic worker - were taken into consideration.
He said that Krishnan had bought the knife to threaten, not kill, his wife and that only one cut was inflicted.
Yesterday, the prosecutor told the court that Krishnan's actions were premeditated and that he had no qualms about carrying out the assault in front of the victim's young child.
The couple had married in a temple ceremony in India in 2011 and Krishnan, who ran a herbal medicine business, came to Singapore in July 2012.
