Subbasal Nerve Density Estimates in Normal and Post-LASIK Corneas by using Two Confocal Microscopes

	Subbasal nerve density, µm/mm²(means ± SD)
Instrument	Normal cornea (n = 18)	Post-LASIK cornea (n = 75)^a	All Corneas (n = 93)
Confoscane 4	10,658 ± 5,581^b	2,477 ± 3,514^c	4,060± 5,124^b
Tandem scanning	5,534 ± 1,850^b	844 ± 983^c	1,752 ± 2,209^b

n, number of confocal microscopy examinations.

Post-LASIK examination were at 1-month (n=10), 3 months(n=26), 6-months1-years (n=29).

P<0.0001, paired, test generalized estimating equal models, confoscan 4 vs. tandem scanning microscope.
