AIM: To explore clinical application of operation in intraocular silicon oil removal, and analyze the complication of silicon oil tamponade and silicon oil removal, the situation reattachment of retinal and the proper timing of silicon oil removal.

METHODS: Intraocular silicon oil removal with active and continues aspiration was performed in the cutting of scleral under microscope.

RESULTS: Totally 59 patients(62 eyes)had completed silicon oil tamponade. 53 eyes had vitreous chamber and intact retina after operation. While the other 9 eyes who experienced redetachment after operation needed the next operation.

CONCLUSION: The timing silicon oil removal is 3 to 6 months after silicon oil injection. Silicon oil removal may reduce the complication related to silicon oil. Rarely eyes were dependent on silicon oil.
