方法：分析2014-01/12于我院行有晶状体眼人工晶状体植入手术的高度近视患者46例92眼，年龄26.13±3.37(19～32)岁，其中男20例(43%)，女26例(57%)，对这些患者分别进行行术前、术后立体视觉分析。

结果：术前患者双眼(92眼)等效球镜10.02±2.71D，术后等效球镜-0.02±0.25D，两组间有统计学差异(t=14.062，P=0.000)。术前近立体视盲患者6例，余患者近立体视为637.50±462.08arcsec，术后无患者近立体视盲，近立体视为126.09±165.78arcsec，两组间比较有统计学差异(Z=-5.725，P=0.000)； 术前远立体视盲患者共12例，余患者远立体视为400.59±257.00arcsec，术后远立体视盲患者共2例，余患者远立体视为152.73±111.65arcsec，两组间比较有统计学差异(Z=-4.976，P=0.000)。

结论：有晶状体眼人工晶状体植入手术可使高度近视患者双眼屈光状态变为正视从而获得清晰视觉，并有效改善其立体视觉。

METHODS:Fourty-six patients(92 eyes)with high myopia were included from January to December 2014. The average age of patients was 26.13±3.37(19～32)years, and 20 males(43%)and 26 females(57%)were observed. Analysis the stereopsis of these patients before and after the implantation of posterior chamber phakic intraocular lens.

RESULTS:The mean spherical equivalent of all the eyes was 10.02±2.71D before and -0.02±0.25D after surgeries. There was significant difference on the spherical equivalent(t=14.062, P=0.000).There were 6 patients with the blind of near stereopsis, the near stereopsis of the rest patients were 637.50±462.08arcsec before the surgeries and there were none with the blind of near stereopsis after surgeries. The near stereopsis of all the patients were 126.09±165.78arcsec after surgeries. There were 12 patients with the blind of far stereopsis, the far stereopsis of the rest patients were 400.59±257.00arcsec before the surgeries. After surgeries there were 2 patients with the blind of far stereopsis, the far stereopsis of the rest patients were 152.73±111.65arcsec. There were both significant differences on the near stereopsis(Z=-5.725, P=0.000)and the far stereopsis(Z=-4.976,P=0.000)before and after surgeries.

CONCLUSION:Posterior chamber phakic intraocular lens implantation not only correct the ametropic of the high myopia, but also improve the visual acuity and the stereopsis.
