This semi-prospective, parallel, comparative investigation evaluated the clinical outcomes and quality of vision (contrast sensitivity, visual function, dysphotopsia, spectacle use, overall satisfaction) after mono- or bilateral implantation of two presbyopia-correcting intraocular lenses (IOL)-the Liberty 677MY or the AT LISA tri 839M-in 50 eyes of 25 cataract patients. Clinical outcomes were assessed 3 and 12 months postoperatively. Eighty-nine percent of eyes implanted with the Liberty IOL and 59% of eyes implanted with the AT LISA IOL achieved a refractive outcome ±0.5 diopters of the target (emmetropia). Refractive outcomes were stable with both lenses. The proportions of eyes with 20/20 uncorrected distance visual acuity (UDVA) and 20/20 uncorrected near visual acuity (UNVA) were higher in the Liberty group than in the AT LISA group (UDVA: 56% vs. 41%; UNVA: 83% vs. 66%). Optical quality assessment results were comparable for the two IOLs. Superior photopic contrast sensitivity was found with the Liberty lens. The rate of Nd:YAG capsulotomy at the 12-month follow-up was 16.7% in the Liberty group and 40.6% for the AT LISA IOL. Considering that both lenses are made from the same material, we propose that the noted differences in clinical outcomes may derive from differences in design and optical surface between the two IOLs.
这项半前瞻性、平行、对比研究评估了25例白内障患者50只眼单眼或双眼植入两种矫正老花眼的人工晶状体（IOL）——Liberty 677MY或AT LISA tri 839M后的临床结果和视觉质量（对比敏感度、视觉功能、畏光、眼镜使用情况、总体满意度）。术后3个月和12个月评估临床结果。植入Liberty人工晶状体的眼中89%以及植入AT LISA人工晶状体的眼中59%达到了目标（正视）±0.5屈光度的屈光结果。两种晶状体的屈光结果均稳定。Liberty组中未矫正远视力（UDVA）和未矫正近视力（UNVA）达到20/20的眼的比例高于AT LISA组（UDVA：56%对41%；UNVA：83%对66%）。两种人工晶状体的光学质量评估结果相当。Liberty晶状体具有更高的明视对比敏感度。在12个月随访时，Liberty组Nd:YAG囊切开术的发生率为16.7%，AT LISA人工晶状体组为40.6%。考虑到两种晶状体由相同材料制成，我们认为观察到的临床结果差异可能源于两种人工晶状体在设计和光学表面上的差异。
