Abstract

Purpose: To evaluate the visual performance in eyes with diffractive intraocular lenses (IOLs) after laser in situ keratomileusis (LASIK).

Methods: This single-center retrospective study evaluated eyes that had diffractive multifocal IOL implantation after previous LASIK or not treated with LASIK (controls). The outcomes' measures were the visual acuities (VAs) at distance and near, spherical equivalent (SE) and contrast sensitivity at one month postoperatively.

Results: The study evaluated 40 eyes of 33 patients. The mean uncorrected logMAR VAs were -0.05 ± 0.13/0.00 ± 0.14 (LASIK group/control group) at distance and 0.10 ± 0.13/0.16 ± 0.18 at near. There was no statistically significant difference between the 2 groups at the VAs. The SE of the LASIK group was -0.06 ± 0.39 D, significantly lower than the control group (0.22 ± 0.45 D) (p < 0.05). The contrast sensitivity of the LASIK group at high spatial frequency was lower than the control group (p < 0.05).

Conclusion: After LASIK, the diffractive multifocal IOL provided good uncorrected distance and near VAs. However, decrease in contrast sensitivity should be considered.

激光原位角膜磨砂术后衍射型多焦人工晶状体植入术的临床研究[j]。

目的:评价激光原位角膜磨圆术(LASIK)术后使用衍射人工晶状体(iol)的视力。方法:本研究采用单中心回顾性研究方法，对先前LASIK术后行衍射多焦IOL植入术或未行LASIK治疗的眼睛(对照组)进行评估。术后1个月的远近视力(VAs)、球面等效视力(SE)和对比敏感度。结果:对33例患者40只眼进行了评估。未校正的平均logMAR VAs在远处为-0.05±0.13/0.00±0.14 (LASIK组/对照组)，在近处为0.10±0.13/0.16±0.18。两组VAs评分差异无统计学意义。LASIK组的SE为-0.06±0.39 D，显著低于对照组(0.22±0.45 D) (p < 0.05)。高空间频率下LASIK组对比敏感度低于对照组(p < 0.05)。结论:在LASIK术后，衍射型多焦人工晶状体具有良好的未矫正距离和近VAs。但是，应该考虑对比度灵敏度的降低。
