带散光多焦点人工晶体治疗高度近视白内障散光的临床观察

The Clinical Study of Toric Multifocal Intraocular Lens in Correcting Corneal Astigmatism and High Myopia after Phacoemulsification

摘要: 目的：观察带散光多焦点人工晶体治疗高度近视白内障散光的稳定性及可靠性。方法：收集我院2016年1月至2016年12月高度近视白内障行超声乳化联合带散光多焦点人工晶体植入的患者23例30眼，术前角膜散光 > 1.5D，患者眼轴在26~28 mm之间。对术前，术后1周，1月，3月，6月患者裸眼视力，最佳矫正远视力，近视力，散光度数及人工晶体散光轴位的观察。结果：术后半年患者裸眼视力 ≥ 0.8者19眼占(63.3%)。术后6月等效球镜−0.5~+0.5D。最佳近视力 ≥ 0.6有27眼占(90%)，患者6个月散光度(0.38 ± 0.15)D与术前(2.51 ± 1.02)D有明显降低有统计学意义(P < 0.05)，术后6月人工晶体平均旋转度(3.16 ± 1.34)。结论：带散光多焦点人工晶体植入矫正白内障角膜散光的效果可靠，稳定性好。

Abstract: Objective: To study the stability and reliability of toric multifocal intraocular lens (IOL) in the pa-tients with high myopia after phacoemulsification. Methods: Twenty-three cataract patients (30 eyes) with high myopia were involved in the study. All the patients with more than 1.5D corneal astigmatism and ocular axis 26 - 28 mm were implanted toric multifocal intraocular lens after phacoemulsification. The uncorrected visual acuity (UCVA), best corrected near and distance visual acuity (BCNVA and BCDVA), residual corneal astigmatism, and mean axis rotation of toric multifocal intraocular lens (IOL) at postoperative 1 week, 1 month, 3 months, 6 months were observed. Results: At postoperative 6 months, the number of patients (19 eyes) UCVA ≥ 0.8 is 63.3% of all, the spherical equivalent is (−0.5 - +0.5), and the number of patients (27 eyes) BCNVA ≥ 0.8 is 90% of all. There were significant differences in patients with corneal astigmatism preoperative (2.51 ± 1.02)D and postoperative 6 months (0.38 ± 0.15)D (P < 0.05). The mean axis rotation of Toric IOL in the study was (3.16 ± 1.34) at postoperative 6 months. Conclusion: The toric multifocal IOL im-plantation makes better UCVA and BCNVA, and it also provides good stability and reliability in corneal astigmatism correction in phacoemulsification.
