title: Intraocular pressure after phacoemulsification in patients with uncontrolled primary open angle glaucoma.
abstract: RATIONALE (HYPOTHESIS): Although cataract and glaucoma represent an increasingly common situation encountered concomitantly, the management of this association is still debatable. OBJECTIVE (AIM): We aimed to assess intraocular pressure dynamics after phacoemulsification in patients with uncontrolled primary open angle glaucoma (POAG).
  
  
  RESULTS
  The present study was designed as a prospective, non-randomized, cohort study. The study population comprised of 38 patients with medically uncontrolled POAG who underwent cataract surgery by phacoemulsification between 2011 and 2012. Most of the patients (32/38, 84.2%) needed glaucoma surgery after a variable time (mean time between surgeries was 11.6 +/- 4.18 months). Mean preoperative IOP decreased with 2,1 +/- 3,7 mmHg at 6 months (CI 95% 1.96 to 3.56) and with 1,9 +/- 3,9 mmHg at 12 months compared with the baseline IOP. Postoperative IOP was statistically significant lower compared with its preoperative value at 6 months (p=9.11 x 10⁻⁸) and at one year (p=9.2 x 10⁻⁵). The difference between mean IOP at 6 months and 1 year after cataract surgery was not statistically significant (p>0.05). Preoperatively, all the patients received topical antiglaucoma therapy. After phacoemulsification, their number did not change statistically significant, but it showed a slight increase. Average number of topical glaucoma medications used preoperatively was 2.66 + / -0.66, while at 6 months after surgery it was 2.71 + / - 0,75 and at 12 months postoperatively, 2.9 +/- 0.53.
  
  
  CONCLUSIONS
  IOP decreased statistically significant after phacoemulsification in patients with uncontrolled POAG, but the decrease was not sufficient for optimal glaucoma management; therefore, many patients needed subsequent glaucoma surgery.
