The Nottingham fighter was brutally knocked out by the Mexican earlier in the year, and many questioned the decision to take an immediate rematch just over three months later.
However, a day after Lara relinquished his world crown due to issues with the weight, Wood boxed the smartest fight of his career to prevail by unanimous decision.
The fear was that Lara, who did not have to make the full weight cut due to failing to make the necessary check-weight on Wednesday, would use that advantage to steamroller his vulnerable opponent.
Instead, Lara hit the deck as early as the second round, Wood landing with an uppercut that was quickly followed by a left hook.
Although Lara did not necessarily look hurt, the expected response did not materialise, Wood never under any persistent pressure like he was in the first fight.
While that had the potential to perplex Wood and his team, they stuck to the gameplan, aware that only a lapse in concentration would cost them the redemption that they craved and deserved.
Once the final bell rang, Wood being announced as the winner was a formality, the judges scoring it 118-109, 116-111 and 118-109 respectively.
