目的 观察有晶状体眼后房型人工晶状体(posterior chamber phackic implantable collamer lens,pICL)植入术对屈光不正患者双眼立体视功能的影响.设计 回顾性病例系列.研究对象 收集2014年10月至2015年10月在贵州医科大学附属医院眼科行pICL植入术的近视性屈光不正患者40例(77眼).方法 将术前最佳矫正视力(best corrected visual acuity,BCVA)和立体视觉分别与术后1、3个月的裸眼视力(uncorrected visual acuity,UCVA)和立体视觉进行比较.主要指标 UCVA、BCVA、立体视觉.结果 术前UCVA和BCVA分别为(0.06±0.06)和(0.85±0.22).术后1个月和术后3个月的UCVA分别为(0.92±0.24)和(0.97±0.25),均较术前BCVA有显著提高(P均=0.000).与术前比较,术后1个月近距离立体视觉无明显改善(P=-0.259);术后3个月近距离立体视觉有明显改善(P=0.016).在＜2.50 D的屈光参差组中,与术前比较,术后3个月的近距离立体视觉有明显改善(P=0.046).在≥2.50 D的屈光参差组中,各组间两两比较,近距离立体视觉差异均无统计学意义(P=0.343、0.158、0.774).与术前比较,术后1个月和术后3个月的远距离立体视觉均有明显改善(P=-0.010、0.000).在＜2.50 D的屈光参差组中,与术前比较,术后3个月远距离立体视觉有明显改善(P=0.001).在≥2.50 D屈光参差组中,与术前比较,术后3个月远距离立体视觉有明显改善(P=0.009).结论 有晶状体眼后房型人工晶状体植入术能显著提高患者的视力,减小双眼的屈光参差,改善双眼远、近距离立体视功能.“,”Objective To observe the effects on the stereopsis after posterior chamber phackic implantable collamer lens (pICL)implantation.Design Retrospective case series.Participants 77 eyes of 40 myopia patients were involved,who were performed pICL implantation in Affiliated Hospital of Guizhou Medical University from October 2014 to October 2015.Methods Preoperative best corrected visual acuity (BCVA) and stereopsis were compared with uncorrected visual acuity (UCVA) and stereopsis postoperative 1 month and 3 month respectively.Main Outcome Measures UCVA、BCVA and stereopsis.Results UCVA and BCVA preoperatively was (0.06±0.06) and (0.85±0.22) respectively.Postoperative 1 month and 3 month,mean UCVA was (0.92±0.24)and (0.97±0.25) respectively.The UCVA of postoperative 1 month and 3 month were obviously improved comparison with the BCVA of preoperative (all P=0.000).The preoperative near stereopsis was no statistically significant difference from that at postoperative 1 month(P=-0.259).The near tereopsis at the postoperative 3 month more significant improve than preoperatively (P=-0.016).In the group of the anisometropia less than 2.50 D,the near stereopsis at the postoperative 3 month more significant improve than preoperatively (P=0.046).In the group of the anisometropia greater than or equal to 2.50 D,there was no statistically significant difference when comparison of the near stereopsis vision between the two groups (P=0.343,0.158,0.774,respectively).The far stereopsis at the postoperative 1 month and postoperative 3 month were more significant improve than preoperatively (P=0.010,0.000,respectively).In the group of the anisometropia less than 2.50 D,the far stereopsis at the postoperative 3 month were more siginificant improve than preoperatively (P=-0.001).In the group of the anisometropia greater than or equal to 2.50 D,the far stereopsis at the postoperative 3 month more siginificant improve than preoperatively (P=0.009).Conclusion The pICL implantation can significantly reduce anisometropia and improve the vision acuity,the near and distance stereopsis.
