A minute or so into injury time, with the score locked at 1-1, Laing stepped up to beat ex-Lancers keeper Alieu Secka with a free-kick and give the team new hope of avoiding a second straight relegation.
Omar Abdsami gave Lancing the lead midway through the second half but play-off chasing Eastbourne levelled five minutes later through Joe Overy.
The win lifted the Lancers above Shoreham at the bottom and they are three points from safety, with that the gap to AFC Varndeanians in 18th.
