BACKGROUND/OBJECTIVES: To evaluate the refractive outcomes, optical performance, and the quality of vision in patients implanted with a new diffractive intraocular lens (IOL), the Intensity Hanita.
SUBJECTS/METHODS: This observational, prospective, longitudinal study included 64 eyes underwent bilateral cataract surgery with the Intensity IOL (Hanita Israel) implantation. Main outcome measures after 6 months were the following visual acuities (VAs) of uncorrected and corrected distance (UDVA and CDVA), uncorrected and distance corrected intermediate VAs (UIVA and DCIVA), uncorrected and distance corrected near (UNVA and DCNVA), refraction, slitlamp biomicroscopy, defocus curve (DFC), high ocular aberrations (HOA), contrast sensitivity (CS), optical quality, subjective quality of vision (QoV) and near activity visual questionnaires (NAVQ).
Sixty-six percent of eyes having UDVA 0.10 logMAR or better. DFC showed maximum vision at distance (0.02 ± 0.07 LogMAR at 0.0 D), with flat decline through intermediate and near vision (0.11 ± 0.08 LogMAR at -1.5 D and 0.12 ± 0.12 at -2.5 D). No significant changes in CS were found (all spatial frequencies, p ≥ 0.06). The RMS of HOA, coma, trefoil, and SA were 0.21 ± 0.10, 0.10 ± 0.06, 0.11 ± 0.07, and 0.00 ± 0.04 μm and the Strehl ratio was 0.12 ± .04 at 6 months. Subjective symptoms (halos and glare) were reported mild but well tolerated, not causing significant disturbance in daily activities. The NAVQ showed high levels of satisfaction performing daily near-vision tasks.
The Hanita Intensity diffractive IOL successfully restores all distances of vision. The flat profile of the monocular defocus curve confirms the five-foci distribution principle that provides vision at all ranges while increasing the depth of focus.
背景/目的：评估植入新型衍射型人工晶状体（IOL）——Hanita Intensity的患者的屈光结果、光学性能和视觉质量。
受试者/方法：这项观察性、前瞻性纵向研究纳入了64只接受双侧白内障手术并植入Hanita Intensity IOL（以色列Hanita公司）的眼睛。6个月后的主要观察指标包括以下未矫正和矫正远视力（UDVA和CDVA）、未矫正和远矫正中间视力（UIVA和DCIVA）、未矫正和远矫正近视力（UNVA和DCNVA）、屈光、裂隙灯显微镜检查、散焦曲线（DFC）、高阶像差（HOA）、对比敏感度（CS）、光学质量、主观视觉质量（QoV）以及近视力活动主观问卷（NAVQ）。
66%的眼睛UDVA达到0.10 logMAR或更好。DFC显示远视力最佳（0.0 D时为0.02±0.07 LogMAR），在中间视力和近视力时呈平缓下降（-1.5 D时为0.11±0.08 LogMAR，-2.5 D时为0.12±0.12）。未发现CS有显著变化（所有空间频率，p≥0.06）。6个月时，HOA、彗差、三叶草像差和球差的均方根分别为0.21±0.10、0.10±0.06、0.11±0.07和0.00±0.04μm，斯特列尔比为0.12±0.04。主观症状（光晕和眩光）报告为轻度但耐受性良好，未对日常活动造成明显干扰。NAVQ显示在进行日常近视力任务时满意度较高。
Hanita Intensity衍射型IOL成功恢复了所有距离的视力。单眼散焦曲线的平缓特征证实了五焦点分布原理，该原理可在增加焦深的同时提供全范围视力。
