Antrim eased their NHL Division 1B relegation worries with a superb comeback victory at Casement Park.
Dayne Peacock netted early for Laois and the visitors held a commanding 1-9 to 0-4 lead at the break.
The Saffrons trailed by 10 before launching their fightback and they levelled after a Conor Carson goal.
Laois forward Chris Murray netted followed by a Shane McNaughton goal and Antrim won it with injury-time points from Neil McNanus and McNaughton.
McNaughton fired over all four Saffrons points in a disappointing first half.
Laois dominated with Chris Murray impressive while Willie Hyland was accurate from frees.
Antrim looked a beaten side early in the second half but they hit five points without reply with McNaughton, McManus and Barry McFall among the scorers.
McFall set up Carson for his goal while Murray netted from a rebound after Hyland's penalty was saved by Seanan McToal.
McNaughton took his tally to 1-7 by scoring Antrim's second goal and the game was level going into added time.
McManus edged the Ulster side in front before the excellent McNaughton sealed the two points.
