Abstract: Objective To evaluate the short-term effects of coreoplasty combined with phacoemulsification and intraocular lens(IOL) implantation for pupil abnormality and cataract. Design Retrospective case series. Participants  Pupillary abnormalities combined with cataract patients 59 cases ( 62 eyes). Methods Coreoplasty combined with phacoemulsification and IOL implantation and(or)vitrectomy of anterior segment were performed based on pupil size, shape and iris condition in 2009-2011. All patients were followed up for 3-6 months. Main Outcome Measures Visual acuity, intraocular pressure (IOP) and iris morphology. Results The preoperative uncorrected visual acuity was better than 0.5 in 7 eyes(11.3%). Small pupil was in 36 eyes (58%). Eye injury with IOP was in 14 eyes (22.6%). Congenital iris coloboma was in 8 eyes (13%). Traumatic aniridia was in 4 eyes (0.06%). IOP increased in 8 people (13%), averaging IOP (32.50±2.50) mm Hg. At the last follow-up, postoperative visual acuity improved in 59 eyes (95%). The  uncorrected visual acuity was better than 0.5 in 23 eyes (37.1%). After surgery in 62 eyes (100%) pupil was round or nearly round, and at central or nearly central position. In  3 eyes （0.05%） pupil was displacement. In 33 eyes (53.2%) pupil diameter was 2.5~ 4.0 mm. Hyphema occurred in 1 eyes intraoperatively. After 1 weeks in 6 eyes existed elevated IOP, averaging IOP (29.0±3.5) mm Hg, of which 3 eyes were performed hypotensive surgery. At 1 month after coreoplasty surgery 3 eyes existed elevated IOP, averaging （24.5±3.5）mm Hg. After 3 to 6 months the IOP in all patietns was normal. Conclusions Coreoplasty combined with phacoemulsification and IOL implantation for the treatment of pupillary abnormalities with cataract patients is safe, effective.
