This retrospective study was performed to determine the postoperative intraocular pressure (IOP) control in patients with glaucoma who underwent phacoemulsification with and without trabeculectomy.
Thirty-five eyes underwent phacoemulsification, and 21 eyes underwent combined surgery. The minimum postoperative follow-up for both groups was 6 months.
The average IOP decreased from 19.7 +/- 4.6 mm Hg preoperatively to 16.3 +/- 3.1 mm Hg in the phacoemulsification group, and from 21.2 +/- 5.9 mm Hg to 14.4 +/- 3.3 mm Hg in the combined group at 6 months (statistically not significant). There was no statistically significant difference between the groups in terms of visual acuity improvement or the number of glaucoma medications.
Cataract surgery, with phacoemulsification alone and combined with trabeculectomy, induces a statistically and clinically significant reduction of IOP in patients with glaucoma.
本回顾性研究旨在确定接受白内障超声乳化术联合或不联合小梁切除术的青光眼患者术后眼压（IOP）的控制情况。
35只眼接受了白内障超声乳化术，21只眼接受了联合手术。两组患者术后的最短随访时间均为6个月。
白内障超声乳化术组患者的平均眼压从术前的19.7±4.6毫米汞柱降至术后6个月时的16.3±3.1毫米汞柱，联合手术组患者的平均眼压从21.2±5.9毫米汞柱降至14.4±3.3毫米汞柱（统计学上无显著差异）。两组在视力改善或青光眼药物使用数量方面无统计学显著差异。
单独采用白内障超声乳化术以及联合小梁切除术的白内障手术，均可使青光眼患者的眼压在统计学和临床上出现显著降低。
