To analyze the objective and subjective visual performances of a new hybrid refractive/aspheric extended depth of focus (EDOF) intraocular lens (IOL).
In this monocentric prospective study patients with bilateral cataracts underwent cataract surgery and were implanted with a Lucidis IOL (SAV-IOL SA, Neuchâtel, Switzerland) in both eyes, 1 week apart from each other. At 3 months from implantation postoperative evaluations included monocular and binocular uncorrected and distance-corrected distant (4 m), intermediate (80 cm, 67 cm) and near (40 cm) visual acuities (UDVA/DCVA, UI80-67VA/DCI80-67VA, UNVA/DCNVA), binocular defocus curves, halometry, contrast sensitivity and objective quality-of-vision measurements. Also, patients were also asked to complete the national eye institute refractive error quality of life (NEI-RQL-42) questionnaire.
Twenty-five patients (50 eyes) were included. The mean postoperative binocular UDVA, UI80VA, UI67VA and UNVA were-0.02 ± 0.13, 0.05 ± 0.09, 0.05 ± 0.08 and 0.03 ± 0.1 LogMar, and did not significantly differ from their corrected counterparts. On binocular defocus curves a VA ≥0.05LogMar was found between +0.50 and - 2.50 D of vergence, whereas the mean distance from the central stimulus on halometry was 1.23 ± 0.01. Mean ocular and corneal radical mean square at 4 mm were 0.31 ± 0.28 and 0.19 ± 0.07, respectively; whereas the mean Strehl ratio was 0.2 ± 0.09.
Lucidis IOLs demonstrated excellent visual performances, especially at close distances while maintain good quality of vision, contrast sensitivity, and overall patient-satisfaction.
分析一种新型折射/非球面扩展焦深（EDOF）人工晶状体（IOL）的客观和主观视觉性能。
在这项单中心前瞻性研究中，双侧白内障患者接受了白内障手术，双眼植入Lucidis IOL（SAV-IOL SA，瑞士纳沙泰尔），手术间隔1周。植入后3个月，术后评估包括单眼和双眼未矫正及距离矫正的远距（4米）、中距（80厘米、67厘米）和近距（40厘米）视力（UDVA/DCVA、UI80 - 67VA/DCI80 - 67VA、UNVA/DCNVA）、双眼散焦曲线、眩光测量、对比敏感度和客观视觉质量测量。此外，还要求患者完成国家眼科研究所屈光不正生活质量（NEI-RQL-42）问卷。
纳入25例患者（50只眼）。术后双眼平均UDVA、UI80VA、UI67VA和UNVA分别为-0.02±0.13、0.05±0.09、0.05±0.08和0.03±0.1 LogMar，与矫正后的对应值无显著差异。在双眼散焦曲线上，在+0.50至-2.50 D的聚散度之间发现视力≥0.05LogMar，而眩光测量中距中央刺激的平均距离为1.23±0.01。4毫米处的平均眼和角膜均方根分别为0.31±0.28和0.19±0.07；而平均斯特列尔比为0.2±0.
