Phacoemulsification combined with goniosynechialysis for therapy of primary angle-closure glaucoma

Objective To observe the effect of phacoemulsification combined with intraocular lens implantation and goniosynechialysis for the therapy of primary angle-closure glaucoma and cataract.Methods Data of 30 patients(37 eyes) with primary angle-closure glaucoma combined with cataract were analyzed retrospectively,including 16 eyes with range of closed-angle≤180° and 21 eyes 180°.All patients were treated with phacoemulsification and intraocular lens implantation combined with goniosynechialysis.The preoperative and postoperative intraocular pressure,anterior chamber angle and visual acuity was monitored.Results After 3 to 24 months′ follow-up period,the corrected visual acuity of post-operation was improved except 2 eyes with optic atrophy.The mean postoperative intraocular pressure(IOP) was(14.31±4.13)mm Hg(1 mm Hg=0.133 kPa),significantly decreased compared with the preoperative IOP[(26.42±3.22)mm Hg;t=5.86,P0.01].The preoperative and postoperative mean central anterior chamber depth was(2.0±0.3)mm and(3.2±0.4)mm.All postoperative chamber angles were wider than the preoperative ones.Conclusions The combined procedure of phacoemulsification and goniosynechiaysis was a safe treatment with few complications and has a good visual outcome in patients with primary angle-closure glaucoma and cataract.
