This study aimed to evaluate ocular surface temperature (OST) in post-COVID-19 patients with different degrees of fever via infrared thermal imaging. There were 16 participants (32 eyes) in the control group, 22 participants (44 eyes) in the moderate and low post-COVID-19 fever group (M & L fever group), and 18 participants (36 eyes) in the high post-COVID-19 fever group (H fever group). All participants underwent an ophthalmic slit lamp examination and ocular thermography. Among the control group, M & L fever group and H fever group, there were no significant differences in the upper eyelid temperature (UET), inner canthus temperature (ICT), outer canthus temperature (OCT), initial central corneal temperature (initial CCT), third-second central corneal temperature (3s-CCT), or sixth-second central corneal temperature (6s-CCT). However, the change in central corneal temperature measured within 1, 3, and 6 s (change in CCT within 1, 3, and 6 s) of the H fever group were significantly greater than those of the control group (0. 15 +/- 0. 12 ^0C vs. 0. 08 +/- 0. 09 ^0C, p = 0. 007; 0. 30 +/- 0. 22 ^0C vs. 0. 17 +/- 0. 17 ^0C, p = 0. 005; 0. 45 +/- 0. 30 ^0C vs. 0. 26 +/- 0. 23 ^0C, p = 0. 004, respectively) and M & L fever group (0. 15 +/- 0. 12 ^0C vs. 0. 08 +/- 0. 08 ^0C, p = 0. 008; 0. 30 +/- 0. 22 ^0C vs. 0. 16 +/- 0. 14 ^0C, p = 0. 001; 0. 45 +/- 0. 30 ^0C vs. 0. 23 +/- 0. 20 ^0C, p
