Korbasova competed only in two individual events at the 2000 Summer Olympics in Sydney. She achieved FINA B-standards of 2:20.38 (200 m backstroke) from the Slovakia Grand Prix in Bratislava and 4:55.45 (400 m individual medley) from the European Championships in Helsinki, Finland. On the first day of the Games, Korbasova placed twenty-fourth in the 400 m individual medley. Swimming in heat one, she came up with a spectacular swim on the dominant backstroke leg to overhaul a five-minute barrier and pick up a second seed in 4:59.05, nearly five seconds behind the leader Georgina Bardach of Argentina. Five days later, in the 200 m backstroke, Korbasova edged out Hungary's Annamária Kiss on the final stretch to establish a Slovak record and a sixth-seeded time of 2:19.37 from heat two, but her relentless effort was worthy enough for a twenty-seventh spot on the morning prelims.
