Comparison of the bacterial composition of ocular surface microbiota using the Bray–Curtis dissimilarity index for the study population. The bacterial composition was compared at the amplicon sequence variant (ASV) level and visualized in a two-dimensional plot with nonmetric multidimensional scaling (NMDS). Conjunctival samples from both eyes of the patients with contact-lens-associated bacterial keratitis (eye with bacterial keratitis (CLABK) and the eye without bacterial keratitis (CLABK_fellow)) were compared with one randomized eye for each participant in the following groups: contact lens users without bacterial keratitis (CL) and non-contact-lens users (NCL). The bacterial composition was not significantly different between groups (pairwise comparison with PERMANOVA); NCL vs. CL p = 1.0; NCL vs. CLABK_fellow p = 0.49; NCL vs. CLABK p = 0.35; CL vs. CLABK_fellow p = 1.0; CL vs. CLABK p = 0.82. Stress ratio = 0.14.
