To compare clinical outcomes after implantation of TECNIS diffractive multifocal intraocular lenses (IOLs) with different add powers.
Prospective, comparative, interventional case series.
Subjects underwent cataract extraction and diffractive multifocal IOL implant. Subjects had an additional add power of +2.75 diopters (D) (Group 1, 23 eyes), +3.25 D (Group 2, 21 eyes), or +4.00 D (Group 3, 21 eyes). Evaluations were performed 1 and 3 months following cataract surgery, including measurement of monocular uncorrected distance visual acuity (UDVA), refractive error (manifest refraction [MR]), and monocular uncorrected near visual acuity (UNVA) at 33, 40, and 50 cm. At 3 months, internal aberrations and contrast sensitivity were evaluated and subjects completed a questionnaire on outcomes satisfaction, visual symptoms, and spectacle use.
Sixty-five eyes (43 subjects) were included. After surgery, no significant differences between groups were observed in UDVA and MR values. UNVA at 33 cm was best in Group 3 (1 month: P = .032; 3 months: P = .031). Three months after surgery, UNVA was best in Group 1 at 50 cm (P = .017). No significant differences in internal aberration and contrast sensitivity were observed between groups and surgical satisfaction was worst in Group 3 (P = .001). A total of 87.0%, 85.7%, and 76.9% had spectacle independence in Groups 1, 2, and 3, respectively (P = .080).
TECNIS diffractive multifocal IOLs with lower add powers provide good vision over longer working distances and excellent distant vision. Subjects with lower add power had greater satisfaction, more spectacle independence, and fewer visual symptoms than those with +4.00 D add.
比较植入不同附加屈光度的TECNIS衍射多焦点人工晶状体（IOL）后的临床结果。
前瞻性、比较性、干预性病例系列研究。
受试者接受白内障摘除和衍射多焦点IOL植入。受试者的附加屈光度分别为+2.75屈光度（D）（第1组，23只眼）、+3.25 D（第2组，21只眼）或+4.00 D（第3组，21只眼）。在白内障手术后1个月和3个月进行评估，包括测量单眼未矫正远视力（UDVA）、屈光不正（显验光[MR]）以及在33 cm、40 cm和50 cm处的单眼未矫正近视力（UNVA）。在3个月时，评估内部像差和对比敏感度，受试者完成一份关于结果满意度、视觉症状和眼镜使用情况的问卷。
纳入65只眼（43名受试者）。手术后，各组之间在UDVA和MR值方面未观察到显著差异。第3组在33 cm处的UNVA最佳（1个月：P = 0.032；3个月：P = 0.031）。手术后3个月，第1组在50 cm处的UNVA最佳（P = 0.017）。各组之间在内部像差和对比敏感度方面未观察到显著差异，第3组的手术满意度最差（P = 0.001）。第1组、第2组和第3组分别有87.0%、85.7%和76.9%的受试者无需佩戴眼镜（P = 0.080）。
附加屈光度较低的TECNIS衍射多焦点IOL在更长的工作距离上能提供良好视力和出色的远视力。附加屈光度较低的受试者比附加屈光度为+4.00 D的受试者满意度更高、更少依赖眼镜且视觉症状更少。
