Purpose: To investigate the effect of liposome encapsulated daunorubicin (DNR) on rabbit eyes when it was used in prevention of posterior capsule opacification (PCO). Methods: The liposome encapsulated DNR was prepared by modified freeze-thawing method. Each eye was injected with 0. 1 ml liposomes (0. 2 mg/ml and 20 μg/ml DNR) into the capsular bag during the extracapsular lens extraction (ECLE) in 10 rabbit eyes respectively. The phosphate buffer solution (PBS) was injected as control. Besides biomicroscope observation and histology examination of all eyes, the concentration of DNR in aqueous humor was also determined by high performance liquid chromatography (HPLC).Results: The morphology of liposome encapsulated DNR were similar to the blank liposome with round or ellipse shape. The encapsulated effeciency of liposome encapsulated DNR was 45. 1%. The inflammatory response was much more severe both in 0. 2 mg/ml and 20μg/ml DNR group than the control after liposome injection. All eyes in DNR group w
