摘要
目的 通过超声诊断学检测方法观察有晶状体眼后房型人工晶状体植入术（ICL）对前房参数引起的改变.方法 利用A超和UBM进行术前术后前房深度、晶状体厚度及ICL后间隙等参数进行测量,同时记录术前术后裸眼视力,最佳矫正视力等数据.结果 A超测量中,前房深度术后（2.54±0.21）mm比术前（3.40±0.30）mm变浅（t=22.648;P≤0.01）;晶状体厚度术后（4.50±0.55）mm较术前（3.76±0.29）mm增加（t=9.261;P≤0.01）;前房晶状体总参数术前（7,16±0.33）mm术后（7.04±0.50）mm差异无统计学意义（t=1.535;P=0.134〉0.05）;ICL晶状体问隙为：（0.26±0.49）mm.UBM测量中,前房深度为：（2.25±2.70）mm,ICL后间隙为：（0.45±0.26）mm,虹膜根部激光孔开放良好,未发现ICL与正常晶状体接触以及位置的异常.术后裸眼视力（0.776±0.414）较术前裸眼视力（0.073±0.056）有明显的提高,平均提高11行以上;术后最佳矫正视力（1.061.4±0.272）较术前最佳矫正视力（0.656±0.321）也有了明显提高（t=13.175;P≤0.01）,平均提高2行以上.术后等效屈光度（-2.05±1.55）D较术前等效屈光度（-17.72±4.87）D得到了很大程度的改善（t=24.819;P≤0.01）.结论 有晶状体眼后房型人工晶状体植入术（ICL）后前房变浅但由于开放的虹膜根切孔的存在无青光眼的发生,术前准确的生物测量能够帮助术后ICL与正常晶状体之间拥有安全的间隙,避免白内障的发生.
Objective To observe the data of anterior chamber after posterior chamber phakic intraocular lens （implantable contact lens, ICL） by ultrasonography method.Methods Anterior chamber depth （ACD）, the thick of lens, the distance between the posterior surface of ICL and the lens was measured by A-ultrasound and ultrasound biomicroscopy （UBM）.Vision acuity （VA） of pre-surgery, VA and best corrected VA （BCVA） of post-surgery were recorded.Results A-ultrasound showed that ACD was （2.54± 0.21 ）mm postoperatively and （3.40± 0.30）mm preoperatively.There was a statistically significant （t=22.648; P≤ 0.01）. The thick of lens was （4.50± 0.55 ）mm postoperatively and （3.76± 0.29 ）mm preoperatively.There was a statistically significant difference （t=9.261; P≤ 0.01 ）.The distance between the post-surface of comea and the post-surface of lens was （7.16± 0.33 ）mm preoperatively and （7.04± 0.50 ）mm postoperatively.There was no significant difference （t=1.535; P=0.134〉0.05 ）.The distance between the posterior surface of ICL and the lens was （0.26± 0.499 ）mm.UBM showed that ACD was （2.25± 2.70 ）mm and the distance between the posterior surface of ICL and the lens was （0.45± 0.26）mm.No contact was found between the ICL and the crystalline lens.The VA of post- operation （0.776± 0.414） was 11 lines higher than that of pre-operation （0.073± 0.056）. There was statistically significant difference （t=13.175; P≤ 0.01） between BCVA of post-operation （1.061± 0.272） and that of pre-operation （0.656± 0.321 ）.The diopter of post-operation （-2.05± 1.55D） was much better （t=24.819;P≤ 0.01） than that of pre-operation （-17.72± 4.87D）.Conclusions ICL implantation for the surgical correction of high myopia is a safe procedure although the anterior chamber depth is decreased after the surgery.Accurate measurement by ultrasound can help avoid the occurrence of cataract coming from operation.
