title: Evaluation of the Ex-PRESS(®) P-50 implant under scleral flap in combined cataract and glaucoma surgery.
abstract: OBJECTIVE
  To evaluate the efficacy and safety of glaucoma drainage device Ex-PRESS(®) P-50 for combined cataract surgery and glaucoma.
  
  
  METHODS
  Patients having cataract and open angle glaucoma or patients with open advanced glaucoma which needed two or more antiglaucoma medications were included. Combined cataract surgery and glaucoma with Ex-PRESS(®) P-50 model placed under scleral flap was performed.
  
  
  RESULTS
  Out of 40 eyes of 40 patients (55% male and 45% female) completed the study during one-year follow-up. The mean of age was 76.6±11.02y. The intraocular pressure (IOP) decreased significantly during the 12-month follow-up from 23.5 mm Hg to 16.8 mm Hg (Wilcoxon signed ranks test, P<0.001). A 59.5% of patients did not need any topical treatment, 10.8% of them needed one active principle, 27% needed two active principles, and 2.7% of them needed three active principles for successful IOP control (<21 mm Hg).
  
  
  CONCLUSIONS
  Combined surgery of phacoemulsification with ExPRESS(®) P-50 lowers IOP from the preoperative baseline and reduces significantly the number of antiglaucoma active principles for IOP control after the operation.
