General Properties of Mechanonociceptor Fibers Recorded From Intact and Injured Corneas at Different Times After Lesion With a Microkeratome

		Injured Corneas (Time After Lesion)
Mechanonociceptors	Intact Corneas	3–8 h	24–48 h	72 h	6–15 Days
Spontaneous activity (imp/s)	0.008 ± 0.004 (4/225)	0.022 ± 0.022 (1/25)	0 ± 0 (0/48)	0 ± 0 (0/29)	0 ± 0 (0/28)
Mechanical threshold (mN)	0.66 ± 0.005	0.50 ± 0.09	0.35 ± 0.02*	0.60 ± 0.14	0.57 ± 0.11
n	242	25	48	29	28

Data are mean ± SEM; n = number of recorded fibers; number in brackets indicate the number of fibers with spontaneous activity/number of recorded fibers. * P < 0.05, Mann–Whitney U test, compared with intact corneas.
