摘　　要：[背景]观察Nd:YAG激光后囊膜切开术对后发性白内障患者最佳矫正视力、眼压及屈光状态的影响.[病例报告]选择2021年1月—2022年12月间邵武市立医院收治的行Nd:YAG激光后囊膜切开术的66例后发性白内障患者作为观察对象,根据后囊膜切口大小的不同分为对照组(切口大小为5.5 mm×5.5 mm,32例)和观察组(切口大小为4.0 mm×4.0 mm,34例).比较两组最佳矫正视力、眼压、屈光状态及前房深度情况.结果见,两组患者术前最佳矫正视力间差异无统计学意义(P>0.05);术后30 d时的最佳矫正视力均明显改善(P<0.05),两组术后30 d时的最佳矫正视力间差异无统计学意义(P>0.05).两组患者术前眼压间差异无统计学意义(P>0.05),术后24 h时的眼压均显著提升(P<0.05),而两组术后眼压间差异无统计学意义(P>0.05).两组患者术前球镜度数、柱镜度数、角膜散光及等效球镜度(SE)间差异均无统计学意义(P>0.05),术后30 d时的球镜度数、柱镜度数及SE均显著降低(P<0.05),角膜散光无明显变化(P>0.05);两组术后30 d时的各项指标间差异无统计学意义(P>0.05).两组患者术前前房深度间差异无统计学意义(P>0.05),术后30 d时的前房深度均显著增加(t=3.940,P=0.000;t=5.034,P=0.000);两组术后30 d时的前房深度间差异无统计学意义(P>0.05).[讨论]Nd:YAG激光后囊膜切开术对后发性白内障患者最佳矫正视力、眼压及屈光状态均有良好的改善作用,且后囊膜切口的大小对患者最佳矫正视力、眼压及屈光状态均无显著影响.BACKGROUND To observe the effect of Nd:YAG laser posterior capsulotomy on optimal corrected visual acuity,intraocular pressure and refractive status in patients with posterior capsule opacification.CASE REPORTS Sixty-six patients with posterior capsule opacification who underwent Nd:YAG laser posterior capsulotomy in Shaowu Municipal Hospital from January 2021 to December 2022 were selected as the observation objects.They were divided into the control group(incision size:5.5 mm×5.5 mm,32 cases)and observation group(incision size:4.0 mm×4.0 mm,34 cases)according to the incision size of the posterior capsule.The optimal corrected visual acuity,intraocular pressure,refractive status and anterior chamber depth were compared between the two groups.The results showed that there was no significant difference in the optimal corrected visual acuity between the two groups before surgery(P>0.05),and the optimal corrected visual acuity at 30 days after surgery was significantly improved(P<0.05),and there was no significant difference in the optimal corrected visual acuity between the two groups at 30 days after surgery(P>0.05).There was no statistically significant difference in IOP between the two groups before surgery(P>0.05),IOP was significantly increased at 24 h after surgery(P<0.05),while there was no statistically significant difference in IOP between the two groups at 24 h after surgery(P>0.05).There were no significant differences in the spherical degree,cylindrical degree,corneal astigmatism and spherical equivalent(SE)between the two groups before surgery(P>0.05),at 30 days after surgery,the spherical degree,cylindrical degree and SE of the two groups were significantly decreased(P<0.05),while the corneal astigmatism of the two groups had no significant change(P>0.05).There was no significant difference between the two groups in various indexes at 30 days after surgery(P>0.05).There was no significant difference in the depth of the anterior chamber between the two groups before surgery(P>0.05),and the depth of t
