Clinical research of phacoemulsification with posterior chamber intraocular lens implantation for glaucoma with different goniosynechia ranges

Abstract

AIM:To study the effect of phacoemulsification with posterior chamber intraocular lens implantation to treat glaucoma with different angle-closure range, which may provide a better way to treat the angle-closure glaucoma.METHODS:There were 47 cases(54 eyes)with angle-closure glaucoma, and all of them underwent phacoemulsification and posterior chamber intraocular lens implantation. According to the range of goniosynechia, these patients were divided into three groups:the eyes with the range of goniosynechia≤1/2 were group A(13 eyes); the eyes with 1/23/4 were group C(23 eyes). We observed the status of anterior chamber angle and the intraocular pressure(IOP)of the three groups at 2wk after operations. RESULTS:Compared to the preoperative condition, the IOP of the three groups at 2wk after operations decreased significantly. The IOP reductions of group B and C were more significant than that of group A, and the differences were significant(PPP3/4 appeared in group B; in group C, there were 5 eyes with goniosynechia>3/4, 1 eye with disappeared anterior chamber, 3 eyes with corneal edema, 1 eye with choroidal hemorrhage. The differences of postoperative complication rate among the three groups was statistically significant(PPCONCLUSION:For patients with angle closure glaucoma who have mild to moderate goniosynechia, phacoemulsification with posterior chamber intraocular lens implantation is an effective way. After operations, their closed anterior angle reopened. But to the patients with severe adhesions, there are more complications after operations, especially the glaucoma may reoccur.
