Abstract

To analyze the cause of fixed intraocular lens (IOLs) pupillary capture in children and investigate the rational methods to reposit intraocular lens. Thirty-one eyes (30 cases) with fixed intraocular lens pupillary capture under 14 years old were analyzed based on clinical data; the causes and the complications were also evaluated. The IOL reposition procedure was performed in 8 cases (8 eyes) with severe complications. Different extent of secondary cataract, posterior iris synechia caused by severe postoperative uveal tract reaction were existed in all 30 cases, corecleisis was occurred in some severe cases. During reposition operation, different extent of lens cortex regeneration in the equator portion of capsule bag was found in all eight cases. Fixed pupillary capture of IOL is the common complication in children after cataract surgery. Severe postoperative uveal tract reaction and secondary cataract and lens cortex regeneration are the major causes of intraocular lens pupillary capture. The intraocular lens could be reposited through iris synechia separation, regenerated lens cortex cleaning and secondary cataract extraction.
