Following the eye surgery, Fu only reached the quarter-finals of the 2018 World Open, where he lost to David Gilbert, and the 2020 European Masters. Since February 2020, Fu has returned to Hong Kong because of the COVID-19 pandemic, with his last appearance being at the 2020 Welsh Open. Due to not playing in any events since then, his ranking has steadily dropped out of the Top 64, but an offer of an invitational tour card means he would not need to qualify to rejoin the tour as a result.
