PurposeTo compare treatment with preservative-free and preserved sodium hyaluronate 0.1% and fluorometholone 0.1% eyedrops after cataract surgery in patients with preexisting dry-eye syndrome.SettingBucheon St. Mary's Hospital, Catholic University of Korea, Seoul, Korea.DesignRandomized controlled study.MethodsPatients with cataract and dry-eye syndrome were randomly divided into 2 groups. Group 1 patients were treated with preservative-free sodium hyaluronate 0.1% and preservative-free fluorometholone 0.1% eyedrops 4 times a day in the first month and twice a day in the second month. Group 2 patients were treated with preserved eyedrops using the same schedule. Ocular Surface Disease Index (OSDI) score, tear-film breakup time (TBUT), Schirmer I test, corneal fluorescein staining, impression cytology, and antioxidant and inflammatory cytokine activities in tears were evaluated.ResultsBoth groups comprised 40 patients. At 2 months, the OSDI score, TBUT, Schirmer I score, fluorescein staining score, impression cytology findings, and goblet cell count were significantly better in Group 1 than in Group 2 (P<.05). The interleukin-1β and tumor necrosis factor-α concentrations were significantly less in the tears of Group 1 patients than in the tears of Group 2 patients, and catalase and superoxide dismutase 2 fluorescence intensities were significantly greater in the tears of Group 1 patients than in the tears of Group 2 patients (P<.05).ConclusionsPreservative-free sodium hyaluronate 0.1% and fluorometholone 0.1% eyedrops can improve the symptoms and signs of dry-eye syndrome after cataract surgery. Preservative-free fluorometholone eyedrops may have antiinflammatory and antioxidant effects in tears of patients with dry-eye syndrome.Financial DisclosureNo author has a financial or proprietary interest in any material or method mentioned.Copyright © 2015 ASCRS and ESCRS.
