title: Prognostic factors in long-term intraocular pressure control following combined phacoemulsification and trabeculectomy.
abstract: We studied 36 consecutive patients who underwent combined phacoemulsification and trabeculectomy to determine prognostic factors associated with intraocular pressure control one year postoperatively. In patients who were either easier (intraocular pressure < 16 mmHg, n = 19) or more difficult (> or = 16 mmHg, n = 17) to control, the mean intraocular pressure increased up to the fourth week postoperatively. In the more difficult to control group, however, the intraocular pressure continued to increase and a statistical difference between groups was noted by the second month postoperatively (P < 0.05). The peak intraocular pressure within the first month postoperatively was lower in patients easier to control long-term (P < 0.005). No statistical difference between groups in the filtering bleb or anterior chamber appearance, or postoperative complications, was noted (P > 0.05). This study suggests combined trabeculectomy and phacoemulsification is safe and effective in controlling intraocular pressure postoperatively. Determining from the early postoperative examination the long-term pressure control, however, is difficult.
