	abstract = {PURPOSE: To compare the clinical characteristics and in vivo confocal microscopy (IVCM) findings of patients with neuropathic corneal pain (NCP) due to refractive surgery (RS-NCP) and herpetic eye disease (H-NCP) to controls. METHODS: Sixteen patients with RS-NCP and 7 patients with H-NCP, and 37 healthy reference age- and sex-matched healthy controls were included to the study. The medical records were reviewed for demographic features, detailed disease history, ocular surface disease index (OSDI), ocular pain assessment survey (OPAS) scores. IVCM images of patients were analyzed and compared to reference controls by two masked observers. RESULTS: The mean pain intensity score for the last 24 h (5.1 {\textpm} 2.4 vs. 3.9 {\textpm} 1.2; p = 0.27), last 2 weeks (6.1 {\textpm} 2.5 vs. 4.8 {\textpm} 2.3; p = 0.13) for RS-NCP vs. H-NCP respectively, and quality of life scores (p = 0.23) were similar in both groups. Quality of life, especially mood (p = 0.06) and enjoying life/relations to others (p = 0.10) were affected in both groups, but were not statistically significant between groups. The mean total nerve density was lower in RS-NCP (5702.4 {\textpm} 4599.0 μm/mm) compared to their respective controls (26,422.8 {\textpm} 4491.0; p \&lt; 0.001) and in the H-NCP group (2149.5 {\textpm} 2985.9) compared to their respective controls (22,948.8 {\textpm} 3169.0; p \&lt; 0.001). Alterations in DC density were similar between all groups (38.3 {\textpm} 48.0 cells/mm in RS-NCP, 61.0 {\textpm} 76.9 in H-NCP, p = 0.95). CONCLUSION: Neuropathic corneal pain patients due to refractive surgery show similar clinical characteristics, pain levels, quality of life impact, and IVCM findings as patients with NCP due to herpetic eye disease.},
