【摘要】：目的利用超声生物显微镜观察高度近视白内障患者超声乳化吸出联合人工晶状体植入术后囊袋张力环对人工晶状体倾斜度和偏心量的影响。方法选取接受白内障超声乳化吸出联合人工晶状体植入术的高度近视白内障患者36例(40眼),平均眼轴长度26.88 mm。按照术中是否植入囊袋张力环分为植入组和对照组。植入组19眼术中植入囊袋张力环,对照组21眼行常规手术。对患者行常规裂隙灯检查,记录术前、术后6个月最佳矫正视力,并于术后6个月行超声生物显微镜检查得到水平和垂直方向的倾斜度、偏心量,计算人工晶状体总的倾斜度和偏心量。结果两组术后最佳矫正视力均比术前有所提高;术前术后两组间最佳矫正视力比较,差异均无统计学意义(均为P0.05)。植入组在水平方向、垂直方向以及总的偏心量分别为(0.15±0.07)mm、(0.30±0.40)mm、(0.11±0.02)mm,在水平方向、垂直方向以及总的倾斜度分别为0.02°±0.11°、0.70°±0.25°、0.21°±0.74°。对照组在水平方向、垂直方向以及总的偏心量分别为(0.26±0.19)mm、(0.32±0.60)mm、(0.24±0.97)mm,在水平方向、垂直方向以及总的倾斜度分别为0.11°±0.31°、1.09°±0.20°、1.24°±0.97°。两组人工晶状体水平方向的偏心量和倾斜度,垂直方向的倾斜度及总的偏心量和倾斜度差异均有统计学意义(均为P0.01);在垂直方向上偏心量差异无统计学意义(P0.05)。结论囊袋张力环对于白内障合并高度近视患者术后人工晶状体的位置具有稳定作用。
[Abstract]:Objective To observe the effect of high myopia with cataract phacoemulsification combined with intraocular lens implantation after capsular tension ring effect on intraocular lens tilt and decentration using ultrasound biomicroscopy. Methods 36 cataract patients with high myopia underwent phacoemulsification combined with intraocular lens implantation cases (40 eyes), the mean axial length of 26.88 mm. according to the intraoperative capsular tension ring implantation into implant group and control group. The implanted capsular Zhang Lihuan were used in 19 eyes, 21 eyes in the control group underwent routine surgery. The patients underwent routine slit lamp examination, recorded before operation, 6 months after surgery, the best corrected visual acuity, inclination, and level and the vertical direction at 6 months after the operation for ultrasound biomicroscopy of the eccentricity, the total calculation of intraocular lens tilt and eccentricity. The results of two groups of best corrected visual acuity were proposed before operation 楂，
