To compare clinical and patient-reported outcomes with bilateral implantation of AcrySof toric or spherical control (Alcon Laboratories Inc) intraocular lenses (IOLs).
Patients with cataract and corneal astigmatism who previously received either an AcrySof toric IOL or an AcrySof spherical control IOL were offered implantation of the same IOL in the fellow eye. Six-month assessments included visual acuity, refractive cylinder, spectacle use, and patient satisfaction.
The study included 62 patients (toric, n=40; control, n=22). All corneal incisions were temporal, with final mean incision sizes of 3.0 mm for the toric IOL and 3.1 mm for the spherical control IOL. A significantly greater proportion of patients with toric IOLs achieved spectacle independence for distance vision and did not require prescription glasses for near or distance vision (P=.0190). Patients with toric IOLs had significantly less residual refractive cylinder (P<.0001) and better binocular distance uncorrected visual acuity (UCVA) (P=.0014) than those with spherical control IOLs.
Patients with bilateral AcrySof toric IOLs achieved superior spectacle freedom, residual refractive cylinder, and distance UCVA compared to patients with bilateral spherical control IOLs.
比较双侧植入AcrySof散光型或球形对照(爱尔康实验室公司)人工晶状体(IOL)的临床和患者报告结局。
向先前接受过AcrySof散光型IOL或AcrySof球形对照IOL的白内障和角膜散光患者提供在对侧眼植入相同IOL的机会。6个月的评估包括视力、屈光柱镜、眼镜使用情况和患者满意度。
该研究纳入了62例患者(散光型,n = 40;对照,n = 22)。所有角膜切口均位于颞侧,散光型IOL的最终平均切口大小为3.0 mm,球形对照IOL为3.1 mm。植入散光型IOL的患者中,实现远距离视力无需眼镜矫正以及近、远距离视力均无需处方眼镜的比例显著更高(P = 0.0190)。与植入球形对照IOL的患者相比,植入散光型IOL的患者残余屈光柱镜显著更少(P < 0.0001),双眼远距离未矫正视力(UCVA)更好(P = 0.0014)。
与双侧植入球形对照IOL的患者相比,双侧植入AcrySof散光型IOL的患者在眼镜自由度、残余屈光柱镜和远距离UCVA方面表现更优。
