To compare visual outcomes, depth of field (DOF), spectacle independence, and patient satisfaction of cataract patients with and without previous myopic laser in situ keratomileusis (LASIK) surgery who received a non-diffractive extended range-of-focus (EROF) intraocular lens (IOL).

Prospective case series.
A total of 50 eyes of 41 patients implanted with the Vivity IOL were divided into Post-LASIK and Virgin groups. Outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), refractive outcomes, defocus curves, subjective DOF, spectacle independence, and Visual Function questionnaire (VF-14) after 3 months postoperatively.
Postoperatively, 70% of the Post-LASIK and 86.7% of the Virgin group had refractive error within ± 0.50 D ( = 0.28). The majority of both groups achieved 20/25 or better UDVA, with no significant differences between groups for UDVA, CDVA and UIVA ( > 0.05). The UNVA was significantly better in the Post-LASIK group (0.31 ± 0.08 logMAR) than Virgin group (0.45 ± 0.10 logMAR, < 0.001). The Post-LASIK group showed a smoother curve with a wider landing area, and better subjective DOF compared to the Virgin group ( < 0.001). Spectacle independence at near ranges in bright light was higher in the Post-LASIK group (81.3 % vs 48 %, = 0.033). Both groups reported high visual satisfaction, but the Post-LASIK group had fewer difficulties with near-distance tasks in the VF-14 questionnaire.
In post-LASIK eyes, this wavefront-shaping EROF IOL was well-tolerated and provided an extended range of vision with significantly better UNVA, fewer difficulties in daily activities and higher spectacle independence for near vision compared to normal eyes.
比较接受非衍射扩展焦深（EROF）人工晶状体（IOL）植入的白内障患者中，有和没有近视激光原位角膜磨镶术（LASIK）手术史的患者的视觉效果、焦深（DOF）、脱镜率和患者满意度。

前瞻性病例系列。
将41例植入Vivity IOL的患者的50只眼分为LASIK术后组和未手术组。观察指标包括术后3个月时的裸眼远视力（UDVA）、矫正远视力（CDVA）、裸眼中视力（UIVA）、裸眼近视力（UNVA）、屈光结果、散焦曲线、主观焦深、脱镜率和视觉功能问卷（VF - 14）。
术后，LASIK术后组70%的患者和未手术组86.7%的患者屈光不正度数在±0.50 D以内（P = 0.28）。两组大多数患者的UDVA达到20/25或更好，两组间UDVA、CDVA和UIVA无显著差异（P > 0.05）。LASIK术后组的UNVA（0.31±0.08 logMAR）明显优于未手术组（0.45±0.10 logMAR，P < 0.001）。与未手术组相比，LASIK术后组的曲线更平滑，着陆区域更宽，主观焦深更好（P < 0.001）。LASIK术后组在明亮光线下近距离的脱镜率更高（81.3%对48%，P = 0.033）。两组均报告有较高的视觉满意度，但在VF - 14问卷中，LASIK术后组在近距离任务方面的困难较少。
在LASIK术后眼中，这种波前塑形的EROF IOL耐受性良好，与正常眼相比，提供了更广泛的视力范围，UNVA明显更好，日常活动困难更少，近视力脱镜率更高。
