PURPOSE To compare two trifocal intraocular lenses (IOLs), the RayOne Trifocal RAO603F IOL (closed-loop haptic IOL; Rayner Intraocular Lenses Limited) and the AT Lisa tri 839 MP IOL (plate-haptic IOL; Carl Zeiss Meditec AG), concerning optical and capsular bag performance. METHODS Patients scheduled for cataract surgery received either a closed-loop haptic IOL or a plate-haptic IOL in the first eye and the other IOL in the second eye. Three months postoperatively, autorefraction and subjective refraction, uncorrected and corrected distance visual acuity at 4 m, 80 cm, and 40 cm, an objective reading test (Salzburg Reading Desk; SRD Vision), a defocus curve, IOL tilt and decentration, a questionnaire about dysphotopsia, and grading of halos with a halometer were performed. RESULTS Eighty-eight eyes of 44 patients were included. Visual acuity was comparable between both IOLs. The closed-loop haptic IOL performed better in the defocus curve at -1.50 diopters (D) (0.08 ± 0.10 vs 0.12 ± 0.09 logMAR; P < .01). The plate-haptic IOL had better contrast sensitivity without glare under mesopic and photopic conditions in miosis (P = .0018 and .002, respectively) and mydriasis (P = .017 and .003, respectively). Significant differences were found for less overall subjective disturbance (P = .047) and starbursts (P = .039) for the plate-haptic IOL, but not for the other positive dysphotopsia symptoms. CONCLUSIONS Both trifocal IOLs delivered good and comparable visual function with low degrees of disturbing dysphotopsia. The closed-loop haptic IOL was slightly superior in the defocus curve, whereas the plate-haptic IOL was slightly superior concerning contrast sensitivity and positive dysphotopsia.

两个衍射三焦人工晶状体的视觉性能：随机试验。

目的 比较两种三焦人工晶状体 (IOL)，即 RayOne Trifocal RAO603F IOL（闭环触觉人工晶状体；Rayner Intraocular Lenses Limited）和 AT Lisa tri 839 MP IOL（平板触觉人工晶状体；Carl Zeiss Meditec AG），关于光学和囊袋性能。方法 计划进行白内障手术的患者在第一只眼中接受了闭环触觉人工晶状体或板式触觉人工晶状体，在第二只眼中接受了另一个人工晶状体。术后三个月，自体验光和主观验光，4 m、80 cm和40 cm的未矫正和矫正远视力，客观阅读测试（Salzburg Reading Desk；SRD Vision），散焦曲线，IOL倾斜和偏心，问卷关于视觉障碍，并用光度计对光晕进行分级。结果 共纳入 44 名患者的 88 只眼。两种人工晶状体的视力相当。闭环触觉人工晶状体在 -1.50 屈光度 (D) 的散焦曲线中表现更好（0.08 ± 0.10 vs 0.12 ± 0.09 logMAR；P < .01）。在瞳孔缩小（分别为 P = .0018 和 0.002）和瞳孔放大（分别为 P = .017 和 .003）的中视和明视条件下，平板触觉人工晶状体具有更好的对比敏感度，没有眩光。发现板式触觉人工晶状体的总体主观干扰较少 (P = .047) 和星光爆裂 (P = .039) 存在显着差异，但其他阳性视觉障碍症状无显着差异。结论 两种三焦人工晶状体都提供了良好且相当的视觉功能，并且具有低度的令人不安的视觉障碍。闭环触觉人工晶状体在散焦曲线上略胜一筹，而平板触觉人工晶状体在对比敏感度和正性视觉障碍方面略胜一筹。[J 屈光手术。2021;37(7):460-465.]。
