摘要
目的使用光学相干断层扫描(optical coherence tomography,OCT)评估有晶状体眼虹膜固定型人工晶状体(intraocular lens,IOL)近视患者植入术后患者房角宽度的变化。方法 28眼(14例)近视患者植入虹膜固定型IOL矫正高度近视。观察术前、术后患者的等效球镜、角膜内皮细胞计数、眼压以及2点、3点、4点、8点、9点、10点钟位的房角宽度。结果术前、术后等效球镜分别为(-12.95±0.77)D、(-0.35±0.08)D,差异有显著统计学意义(P<0.001)。术前、术后角膜内皮细胞计数分别为(2859.38±62.27)mm-2、(2783.92±62.67)mm-2,差异有统计学意义(P=0.012)。术前、术后眼压分别为(11.87±0.40)mmHg(1kPa=7.5mmHg)、(11.80±0.40)mmHg,差异无统计学意义(P=0.800)。术后3个月,3点、9点钟位房角较术前变窄,差异均有统计学意义(均为P<0.05),其他方位房角宽度术前、术后差异均无统计学意义(均为P>0.05)。结论植入虹膜固定型IOL后高度近视患者部分房角变窄,术后应对患者前房变化情况进行随访观察。
Objective To evaluate the changes of anterior chamber angle width after the implantation of iris-fLxated intraocular lens(IOL) in phakic eyes by optical co- herence tomography(OCT). Methods A total of 28 eyes( 14 cases) with high myopia were treated with the implantation of iris-fixated IOL. Spherical equivalent, corneal en- dothelial density, intraocular pressure, and angles at 2,3,4,8,9 and l0 O' clock positions before and after operation were observed. Results The preoperative and postopera- tive spherial equivalent were ( - 12.95 ± 0.77 ) D and ( - 0.35 ± 0.08 ) D, respectively, and there was significant difference between them (P 〈 0. 001 ). The preoperative and post- operative corneal endothelial density were ( 2859. 38 ± 62.27 ) nun-2 and ( 2783.92 ± 52. 57) mm-2, respectively, and there was significant difference between them (P = 0. 012). The preoperative and postoperative intraocular pressure were (11.87 ± 0. 40 ) mmHg ( 1 kPa = 7.5 mmHg) and ( 11.80 ± 0.40) mmHg, respectively and there was no difference between them(P = 0. 800 ). At postoperative 3 months, the angles at ] and 9 O' clock positions became lower than those before the operation and there was signifi- cant difference (P 〈 0. 05 ), but there was no significant difference between others ( all P 〉 0. 05 ). Conclusion There is partial narrowing of anterior chamber angle after the implantation of iris-fixated IOL, which shows that the follow up after operation is necessary.
