Preoperative and postoperative intraocular pressure, aqueous flare, corneal thickness, and signs and symptoms were recorded before the operation and1 wk following treatments. RESULTS： There were no statistically significant differences between the two groups in corneal thickness（P ≥0.629）, aqueous flare（P ≥0.398）, and signs and symptoms scores（P ≥0.350） at each time point. Ocular hypertension was only observed in two eyes in the tobramycin/dexamethasone group. CONCLUSION： Fluorometholone combined with levofloxacin treatment shows comparable efficacy but without the tendency to increase intraocular pressure;thus, it might be a better regimen for postoperative use.展开更多

The results were compared to that of the conventional methods (dual wavelength and first derivative of ratio spectra). The suggested methods were validated in compliance with the ICH guidelines and were successfully applied for determination of SCG and FLU in their laboratory prepared mixtures and commercial ophthalmic solution. The novel method showed significant advantages over the conventional methods regarding simplicity, minimal data manipulation and maximum reproducibility and robustness;which enabled the analysis of binary mixtures with overlapped spectra for routine quality control testing with quite satisfactory.展开更多
