Eye Cue's appointment as the Macedonian representative was announced on 13 February 2018, while their song, "Lost and Found", was presented to the public on 11 March 2018.

Performing during the show in position 11, "Lost and Found" was not announced among the top 10 entries of the first semi-final and therefore did not qualify to compete in the final.

On 30 October 2017, the European Broadcasting Union (EBU) stated that the nation would not be allowed to participate at the 2018 Eurovision Song Contest as MRT no longer had access to their services due to the non-payment of debt amounting nearly 22 million euros.

[7] On 13 February 2018, the broadcaster announced that the band Eye Cue had been selected to represent Macedonia in Lisbon, performing the song "Lost and Found".

[9] On 11 March 2018, "Lost and Found" was presented to the public along with the official music video, directed by Jovan Kucinovski, during the MRT evening news programme Dnevnik 2.

[14] On 14 April, Eye Cue performed during the Eurovision in Concert event which was held at the AFAS Live venue in Amsterdam, Netherlands and hosted by Edsilia Rombley and Cornald Maas.

[20] The Macedonian performance featured the members of Eye Cue performing on stage; Marija Ivanovska wore a short metallic pink dress which she later removed to reveal a grey and pink netted top with grey denim shorts, while Bojan Trajkovski wore a white patterned shirt and black pants.

The band was joined on stage by three dancers, which also performed backing vocals, in black body suits with pink and orange frills.

[23] At the end of the show, Macedonia was not announced among the top 10 entries in the second semi-final and therefore failed to qualify to compete in the final.

Each nation's jury consisted of five music industry professionals who are citizens of the country they represent, with their names published before the contest to ensure transparency.

This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.
