Abstract:
AIM: To determine the effect of phacoemulsification and intraocular lens (IOL) implantation for angle closure glaucoma previously treated by laser iridotomy.METHODS: Thirty-nine patients(39 eyes )with angle closure glaucoma previously treated by laser iridotomy and cataract were divided into two groups according need for anti-glaucoma medications for controlling intraocular pressure (IOP) or not. All the patients underwent phacoemulsification and foldable IOL implantation and were followed up 3 months postoperatively.RESULTS: The best-corrected visual acuity(BCVA) of both groups improved significantly (P<0.05). The post-operative IOP of group I at 3 months was 15.72±3.02mmHg,and that of group Ⅱwas 16.30±3.81mmHg. The IOP of both group decreased significantly(P<0.05). The central anterior chamber depth of group I was deepened from 1.64±0.45mm preoperatively to 3.21±0.41mm at 3 months postoperatively,group Ⅱ was deepened from 1.92±0.52mm preoperatively to 3.18±0.39mm at 3 months postoperatively. The postoperative central anterior chamber depth of both groups increased significantly(P<0.05).Anterior chamber angle was much wider postoperatively.CONCLUSION: Phacoemulsification and IOL implantation was effective for angle closure glaucoma previously treated by laser iridotomy,and can improve visual acuity and completely relieve the pupillary block of angle closure glaucoma.
