title: Reduction of intraocular pressure and improvement of vision after cataract surgeries in angle closure glaucoma with concomitant cataract patients.
abstract: OBJECTIVE
  This study is to compare the efficacy of three different cataract surgeries in eyes with angle closure glaucoma (ACG) with concomitant cataract.
  
  
  METHODS
  A retrospective comparative analysis of 106 ACG patients (112 eyes) with concomitant cataract was conducted between February, 2012 and February, 2014. Clinical outcomes of ACG patients with concomitant cataract underwent phacoemulsification and intraocular lens implantation (group A, n = 34, 36 eyes, angle closure < 180°); combined phacoemulsification, intraocular lens implantation, and goniosynechialysis (group B, n = 43, 45 eyes, angle closure, 180°~270°); and combined phacoemulsification, intraocular lens implantation, and trabeculectomy (group C, n = 29, 31 eyes, angle closure > 270°) were compared during a 6-month follow-up.
  
  
  RESULTS
  There were no statistical differences among the 3 groups in pre-operative or post-operative average visual acuity (VA), intraocular pressure (IOP), anterior chamber depth (ACD), and angle opening distance (AOD) (all P > 0.05). Post-operative VA, IOP, ACD, AOD and the degree of angle opening in the 3 groups were all improved as compared with pre-operative levels (all P < 0.05). No statistical difference was detected among the 3 groups in the incidence of complications (χ(2) = 0.376, P = 0.829).
  
  
  CONCLUSIONS
  Phacoemulsification alone, combined phacoemulsification/goniosynechialysis, and combined phacoemulsification/trabeculectomy provide safe, effective, predictable, and stable options of cataract surgery for treatment of ACG with concomitant cataract.
