PURPOSE: To evaluate the efficacy of 0.05% cyclosporine A on tear film parameters and corneal aberration after cataract surgery. METHODS: Patients who underwent cataract surgery were divided into 2 groups. Patients in Group I (23 eyes) were treated with cyclosporine A from 1 week before surgery to 3 months after surgery. Patients in Group II (24 eyes) underwent surgery without cyclosporine treatment. Tear film break-up time (BUT), Schirmer's test I, Oxford scheme, Ocular surface disease index (OSDI), and corneal aberrations were evaluated before surgery and at 1 and 3 months after surgery. RESULTS: In Group I, BUT was significantly improved at 3 months (p = 0.026) after surgery compared with the preoperative value. OSDI decreased significantly at 1 (p = 0.033) and 3 months (p = 0.003) after surgery compared with the preoperative value. However, there were no significant differences between preoperative and postoperative values of BUT and OSDI in Group II. Schirmer's test results and the Oxford scheme were not significantly changed in either group. Preoperative root mean square (RMS) total values were not different between the 2 groups, but was different at postoperative 3 months (p = 0.015). Group I had a significantly lower value for total RMS than Group II. In Group I, Coma 7 (Z3(-1)) (p = 0.018) and spherical aberration (Z4(0)) (p = 0.031) were significantly decreased after surgery. In Group II, Trefoil 6 (Z3(-3)) (p = 0.033) was significantly increased after surgery. CONCLUSIONS: 0.05% cyclosporine A may be effective for improving dry eye syndrome and corneal aberration after cataract surgery.

PURPOSE: Dense breasts have been suggested as a risk factor for breast cancer, but controversy still remains. This study evaluates the association of reproductive and hormonal factors with dense breasts among Korean women. MATERIALS AND METHODS: Using a cross-sectional design, 516 women were recruited and classified for breast density patterns as being either fatty or dense, using the Breast Imaging Reporting and Data System (BI-RADS) of the American College of Radiology. Univariate and multivariate logistic regression models were used for statistical analysis. RESULTS: In univariate logistic regression, older age, higher body mass index, older age at menarche, and oral contraceptive use were associated with more fatty breasts. On the contrary, longer duration of education, alcohol consumption, lower parity, menopause and use of hormone replacement therapy were associated with dense breasts. After adjustment, age and body mass index were inversely associated with breast density (p-value for trend <0.01, respectively), whereas nulliparous and premenopausal status were positively associated. Compared to women who had > or =2 children, nulliparous women had an 11.8-fold increase of dense breasts (p-value for trend <0.01). Compared to postmenopausal women, premenopausal women had 2.4-fold increase of dense breasts (odds ratio, 2.42; 95% confidence interval, 1.36 to 4.32). CONCLUSION: Young age, lower body mass index, lower parity, and premenopausal status were significantly associated with dense breasts in Korea.
