有晶状体眼后房型人工晶状体植入术对高度近视的疗效

目的：探讨有晶状体眼后房型人工晶状体(implantable contact lens，ICL)植入术对高度近视患者的临床治疗效果。

方法：选取2014-06/2015-06经我院检查确诊为高度近视患者34例68眼，均给予ICL植入术进行治疗。观察治疗后屈光度、视力恢复情况、中央前房深度、角膜内皮细胞计数和眼压情况。

结果：术后1、3、6mo，1、2a的等效球镜屈光度、中央前房深度、裸眼视力、最佳矫正视力恢复情况均优于术前，差异有统计学意义(P<0.05)。术后1、3、6mo，1、2a的角膜内皮细胞计数和眼压情况与术前比较，差异无统计学意义(P>0.05)。术后1、3mo，1、2a的裸眼视力、最佳矫正视力、等效球镜屈光度、中央前房深度比较，差异无统计学意义(P>0.05)。

结论：高度近视患者采用ICL植入术进行治疗，能够改善等效球镜屈光度和中央前房深度，提高裸眼视力，同时对患者眼压和角膜内皮细胞影响较小，效果维持及安全性较好。

Correction effect of phakic posterior chamber implantable contact lens implantation on high myopia

AIM: To analyze the clinical efficacy of phakic posterior chamber implantable contact lens(ICL)implantation on high myopia patients.

METHODS: Thirty-four patients(68 eyes)who checked and diagnosed as high myopia in our hospital from June 2014 to June 2015 were selected as the clinical research subjects, and all the patients were given phakic posterior chamber intraocular lens implantation treatment. The diopter, visual acuity recovery, central anterior chamber depth, corneal endothelial cell count, and intraocular pressure after treatment were observed.

RESULTS: The equivalent spherical refraction, central anterior chamber depth, uncorrected visual acuity and best corrected visual acuity recovery at 1, 3 and 6mo, 1 and 2a after treatment were better than those before treatment, and the differences were statistically significant(P<0.05). There were no significant differences in corneal endothelial cell count and intraocular pressure at 1, 3 and 6mo, 1 and 2a after treatment compared with those before treatment(P>0.05). There were no significant differences in uncorrected visual acuity, best corrected visual acuity, equivalent spherical refraction and central anterior chamber depth at 1, 3mo and 1 and 2a after treatment(P>0.05).

CONCLUSION: The application of phakic posterior chamber intraocular lens implantation for the treatment of high myopia patients can improve the equivalent spherical refraction and central anterior chamber depth, improve uncorrected visual acuity, meanwhile, it has less effect on the patient''s intraocular pressure and corneal endometrial cells, the effect maintenance and safety is better which meet their expectations.
