[Preliminary Clinical Study on the Management of Angle-closure Glaucoma by Phacoemulsification with Foldable Posterior Chamber Intraocular Lens Implantation]

Objective: To investigate the clinical results of phacoemulsification with foldable posterior chamber intraocular lens (PC-IOL) implantation in the management of angle-closure glaucoma with cataract.

Methods: Phacoemulsification with PC-IOL implantation performed on 47 eyes (42 cases) with angle-closure glaucoma and cataract was retrospectively studied, including 26 eyes with primary acute angle-closure glaucoma, 12 eyes with primary chronic angle-closure glaucoma, 5 eyes with secondary acute angle-closure glaucoma and 4 eyes with secondary chronic angle-closure glaucoma.

Results: After a mean postoperative follow-up of (18.40 +/- 9.51) months, the intraocular pressure was reduced from a preoperative mean of (25.47 +/- 18.43) mm Hg to a postoperative mean of (11.99 +/- 4.48) mm Hg (t = 4.918, P < 0.001). The mean anterior chamber depth was (1.69 +/- 0.46) mm preoperatively and (2.28 +/- 0.36) mm postoperatively (t = 7.738, P < 0.001). The best-corrected visual acuity was improved in 41 of 47 eyes (87.2%).

Conclusion: Phacoemulsification with posterior chamber foldable intraocular lens implantation can be a good alternative in treating angle-closure glaucoma with cataract.
