Sixty-two participants were recruited, and 12 of them were not enrolled because they had undergone previous treatments for ocular surface diseases. The participants were adult patients with cataract, exhibiting normal lid position; they did not present any other ocular disease and did not meet the exclusion criteria of the clinical trial. Fifty subjects were enrolled in the study. The randomized subjects received treatment with 0.05% CsA (group A) or 0.5% carboxymethyl cellulose (CMC) (group B) over the 3 months following the cataract surgery. Subjective and objective assessments were performed at preoperative and postoperative visits. Ocular Surface Disease Index (OSDI), tear breakup time (TBUT), and Schirmer\u2019s I test were performed by the same surgeon, and LLT and meiboscore were determined using the LipiView<jats:sup>\u00ae<\/jats:sup> interferometer.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Fifty subjects subjects enrolled consisted of men (50%) and women (50%), with a mean (SD) age of 65.94 (10.35) years. Four subjects in group A and five in group B were excluded from the analysis as they were lost to follow-up within 1 month after cataract surgery. Thus, the study comprised 41 eyes of 41 subjects; 21 subjects were treated with CsA and 20 subjects with CMC. Comparing the clinical measurements between groups A and B taken at the last visit, while controlling the effects of the preoperative values, TBUT and LLT showed significant differences (<jats:italic>p<\/jats:italic> = 0.035 and <jats:italic>p<\/jats:italic> = 0.047, respectively, by ANCOVA). The TBUT between the subjects using CsA and those using CMC after cataract surgery showed a significant difference during follow up (<jats:italic>p<\/jats:italic> = 0.003 by repeated measures ANOVA). In the multivariate analysis, preoperative LLT and the use of CsA were found to be independent parameters for postoperative LLT (R<jats:sup>2<\/jats:sup> = 0.303; <jats:italic>p<\/jats:italic> = 0.008 and <jats:italic>p<\/jats:italic> = 0.045, respectively), whereas the follow-up duration exhibited a positive correlation with the difference between the preoperative and postoperative values of LLT in the group treated with CsA (R<jats:sup>2<\/jats:sup> = 0.738 and <jats:italic>p<\/jats:italic> &lt; 0.001).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>Treatment with 0.05% CsA following cataract surgery is effective in improving TBUT and LLT in comparison with 0.5% CMC. A higher preoperative value of LLT and the postoperative use of CsA could be significant determinants of a higher postoperative LLT value.<\/jats:p>\n<\/jats:sec>\n<jats:sec
