Abstract Background To compare and evaluate objective and subjective clinical parameters between 0.05% cyclosporine nanoemulsion (CsN) and 0.15% hyaluronic acid (HA) administration in patients with mild-to-moderate dry eyes. Methods In this prospective, randomized, double-masked, single-center, and placebo-controlled parallel study, patients with mild-to-moderate dry eyes were randomly allocated to be treated with 0.05% CsN or 0.15% HA twice daily. Patients were followed-up at 4, 8, and 12 weeks. Objective and subjective parameters were evaluated during each visit. Results A total of 35 patients were enrolled in this study. Compared with baseline, tear film break-up time and fluorescein staining scores at 4, 8, and 12 weeks significantly improved in the CsN group. However, the Schirmer I test showed no statistically significant change until week 12. Using the Symptom Assessment in Dry Eye (SANDE) score, both groups gradually showed significant improvement compared with baseline values. However, the Dry Eye-Related Quality-of-life Score Questionnaire (DEQS) showed no statistically significant change during the treatment period. Conclusions Both 0.05% CsN and 0.15% HA administration twice a day effectively improved the objective signs and subjective symptoms of patients with mild-to-moderate dry eyes. However, patients treated with 0.05% CsN experienced greater and faster improvement.

Abstract Background To evaluate the effects of lid debris debridement and meibomian gland expression (MGX) on extracellular matrix metalloproteinase-9 (MMP-9) levels and clinical outcomes of moderate and severe MGD. Methods In this retrospective case series study, a total 48 eyes of 24 patients with moderate and severe MGD underwent one session of lid debris debridement using the BlephEx combined with MGX. We evaluated the tear film break-up time (TBUT), corneal and conjunctival fluorescein staining scores, Schirmer 1 test, biomicroscopic examination of lid margins and meibomian gland (MG), ocular surface disease index (OSDI) questionnaire score, and extracellular MMP-9 levels using a point-of-care MMP-9 immunoassay device before and 4 weeks after lid debris debridement and MGX. Linear mixed model and generalized estimating equations model were used to evaluate possible differences. Results There were significant improvements in the TBUT (P = 0.002), SICCA and Oxford staining scores (all P

Abstract Background To evaluate the clinical outcomes of bilateral mix-and-match implantation of diffractive multifocal intraocular lenses (IOLs) with different add powers. Methods We retrospectively reviewed the medical records of 18 patients who underwent bilateral mix-and-match implantation of diffractive multifocal IOLs with different add powers. Multifocal IOLs with add powers of + 2.75 diopters (D) and + 4.00 D were implanted into the patients’ dominant and nondominant eyes, respectively. At 1 and 3-month postoperatively, monocular and binocular visual acuity was measured using logMAR charts and manifest refraction was performed. Specifically, logMAR charts were used to measure uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), and corrected distance visual acuity (CDVA). Defocus curves, contrast sensitivity, and patient satisfaction were assessed at 3-month postoperatively. Results Binocular logMAR measurements (mean ± standard deviation) at 3-month postoperatively were 0.01 ± 0.04 (UDVA), 0.16 ± 0.05 (UIVA), and 0.11 ± 0.07 (UNVA). Postoperative spherical equivalent was − 0.43 ± 0.35 D and − 0.39 ± 0.21 D in the dominant and nondominant eyes, respectively. Defocus curves showed significant differences between − 1.50 and − 4.00 D among binocular, dominant, and nondominant eye measurements, except between − 2.50 and − 3.00 D. Eyes implanted with + 2.75 and + 4.00 D IOLs showed good contrast sensitivity under photopic and mesopic conditions. Over 80% of patients reported high satisfaction with their near vision. Conclusions Bilateral mix-and-match implantation of diffractive multifocal IOLs with add powers of + 2.75 D and + 4.00 D showed good near, intermediate, and far vision.
