目的评价晶状体超声乳化手术对早期原发性闭角型青光眼合并白内障的疗效。方法对64例原发性闭角型青光眼合并白内障患者,随机分为A组32例32眼(晶状体超声乳化吸出联合后房人工晶状体植入术)和B组32例32眼(周边虹膜切除术),观察两组术前术后眼压、前房深度、前房角及视力情况。结果 A组术后1d眼压升高,术后3d以后恢复正常。术后中央前房平均深度为(2.62±0.33)mm,与术前中央前房平均深度(1.54±0.38)mm比较,差异有统计学意义(P<0.05)。术后房角增宽,视力提高,与术前比较差异有统计学意义。B组术后眼压、前房深度、房角增宽程度及视力,与术前比较差异均无统计学意义。结论晶状体超声乳化吸出联合后房人工晶状体植入对早期原发性闭角型青光眼合并白内障,具有加深前房、开放前房角和提高视力的效果,而且又可避免青光眼的发作,是一种安全有效的手术方法。
Objective To evaluate the effect of phacoemulsification on early primary angle-closure glaucoma with cataract. Methods Sixty-four patients with primary angle-closure glaucoma and cataract were randomly divided into group A (32 eyes) (phacoemulsification combined with posterior chamber intraocular lens implantation) and group B (32 eyes) (peripheral iridectomy ), The two groups were observed before and after intraocular pressure, anterior chamber depth, anterior chamber angle and visual acuity. Results The intraocular pressure of group A was increased on the 1st day after operation and returned to normal after 3d. The average depth of the central anterior chamber was (2.62 ± 0.33) mm, which was significantly different from that of the preoperative central anterior chamber (1.54 ± 0.38) mm (P <0.05). Postoperative widened angle, visual acuity, compared with the preoperative difference was statistically significant. The postoperative IOP, the depth of anterior chamber, the degree of widened angle and visual acuity in group B were not statistically different from those before operation. Conclusion Phacoemulsification combined with posterior chamber intraocular lens implantation in early primary angle-closure glaucoma combined with cataract has the effect of deepening anterior chamber, opening anterior chamber angle and improving visual acuity, and can prevent the onset of glaucoma Safe and effective surgical methods.
