[Analysis, prospect and treatment of causes of phacoemulsification complications].

OBJECTIVE: To analyse the causes of different complications of phacoemulsification and to investigate their principles of treatment and prevention. METHOD: The causes of different complications in 187 (180 cases) of 2,250 eyes having undergone phacoemulsification were analyzed. RESULTS: Intraoperatively, the common complications of phacoemulsification were posterior capsular rupture in 70 eyes (3.1%), iris damage in 16 eyes (0.7%), iris prolapse in 6 eyes (0.3%), drop of lens fragments into vitreous in 3 eyes (0.1%) and tear of Descernent's membrane in 4 eyes (0.2%). The common complications after the operation were corneal endothelial edema in 89 eyes (4.0%), corneal decompensation in 2 eyes (0.1%), temporary intraocular hypertension in 28 eyes (1.2%), pupillary dilatation in 7 eyes (0.3%), retinal detachment in 8 eyes (0.4%), cystoid macular edema in 24 eyes (1.1%) and displacement of intraocular lens in 8 eyes (0.4%). CONCLUSIONS: The different complications can be diminished following the popularization and development of phacoemulsification. It should be properly managed once the complication has occurred, and good operative effects can be obtained.
