Sumario: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). Methods and 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. Discussion. 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.
