title: Intraocular pressure in nonglaucomatous eyes with pseudoexfoliation syndrome after cataract surgery.
abstract: OBJECTIVE
  To investigate the course of the intraocular pressure (IOP) in nonglaucomatous patients with pseudoexfoliation (PSX) syndrome after cataract surgery.
  
  
  METHODS
  In a prospective age-matched controlled clinical study, 23 consecutive patients with PSX were studied and compared with a control group of 23 patients. The IOP was measured by applanation tonometry preoperatively, and postoperatively on day 1, after 4 weeks, and after 6 months. All patients were operated on with a self-sealing 7-mm scleral tunnel incision, phacoemulsification, and posterior chamber intraocular lens (IOL) implantation.
  
  
  RESULTS
  Preoperatively the IOP was similar between both groups (P = .962). At the first postoperative day the IOP was below 22 mm Hg in all cases. After 4 weeks and 6 months a mean decrease of 3.88 mm Hg (P = .001) in the control group and of 3.15 mm Hg (P = .002) in the PSX group was observed; this difference was not statistically significant (P = .543).
  
  
  CONCLUSIONS
  At 1 day postoperatively no pressure increase was observed in the eyes with PSX after scleral tunnel incision and phacoemulsification. Six months after cataract extraction with IOL implantation, the tension level decreased in the presence of PSX similarly as in normal eyes.
