To evaluate the clinical outcomes after cataract surgery with implantation of a new diffractive multifocal intraocular lens with a lower near addition.
A prospective multicenter clinical study including 44 eyes of 44 patients (age range: 43 to 82 years) that underwent cataract surgery with implantation of the Tecnis ZLB00 multifocal intraocular lens (Abbott Medical Optics, Santa Ana, CA). Changes in uncorrected and corrected distance, intermediate, and near visual acuity, and manifest refraction were evaluated during a 3-month follow-up. Additionally, patients were asked about photic phenomena and spectacle dependence.
Postoperative spherical equivalent was within 0.50 and ± 1.00 diopters of emmetropia in 91.2% and 100% of eyes, respectively. Postoperative monocular uncorrected distance, near, and intermediate visual acuities were 0.10 logMAR (20/25 Snellen) or better in 82.5%, 86.5%, and 68.8% of eyes, respectively. All eyes achieved monocular corrected distance and near visual acuity of 0.10 logMAR (20/25 Snellen) or better. All patients reported to be satisfied with the outcomes of the surgery. Only 6 patients (13.6%) required the use of spectacles for some daily activities postoperatively, and 8 patients (18.2%) reported mild perception of halos.
The introduction of low addition multifocal intraocular lenses follows a trend to increase intermediate visual acuity. Still, a near addition of +3.25 diopters reached satisfying near results and led to high patient satisfaction.
评估植入一种新的低近附加度衍射多焦点人工晶状体后白内障手术的临床效果。
一项前瞻性多中心临床研究，纳入44例患者（年龄范围：43至82岁）的44只眼，这些患者接受了白内障手术并植入了Tecnis ZLB00多焦点人工晶状体（雅培医疗光学公司，加利福尼亚州圣安娜）。在3个月的随访期间评估未矫正和矫正的远、中、近视力变化以及显验光。此外，询问患者有关光现象和眼镜依赖情况。
术后等效球镜度分别在91.2%和100%的眼中处于正视眼的±0.50和±1.00屈光度范围内。术后单眼未矫正远视力、近视力和中视力分别在82.5%、86.5%和68.8%的眼中达到0.10 logMAR（20/25 Snellen）或更好。所有眼的单眼矫正远视力和近视力均达到0.10 logMAR（20/25 Snellen）或更好。所有患者均报告对手术结果满意。仅6例患者（13.6%）术后在一些日常活动中需要使用眼镜，8例患者（18.2%）报告有轻度光晕感。
低附加度多焦点人工晶状体的引入顺应了提高中视力的趋势。尽管如此，+3.25屈光度的近附加度仍取得了令人满意的近视力结果，并使患者满意度较高。
