目得：比较单光学部或双光学部可调节人工透镜（IOL）眼的视觉和眼部光学性能，特别关注近视力结局。单位：Vissum Instituto Oftalmologico de阿利坎特，Miguel埃尔南德斯University，阿利坎特，Spain。设计：前瞻性连续非随机干预性比较临床研究。A组植入单光学部可调节IOL（Crystalens HD），B组植入双光学部可调节IOL（Synchrony）。术后随访6个月，观察远、近视力、对比敏感度、眼像差、阅读能力和离焦曲线。结果：A组27眼，B组26眼。患者年龄范围为59 - 82岁。B组的裸眼视力和矫正远视力明显更好（P =.13）。在离焦曲线上，B组在几个离焦水平上的视力均明显优于对照组（P <0.05）。
PURPOSE: To compare the visual and ocular optical performance in eyes with a single-optic or a dual-optic accommodating intraocular lens (IOL) with particular attention to near-vision outcomes.SETTING: Vissum Instituto Oftalmologico de Alicante, Miguel Hernandez University, Alicante, Spain.DESIGN: Prospective consecutive nonrandomized interventional comparative clinical study.METHODS: Eyes with cataract were divided into 2 groups. Group A had implantation of a single-optic accommodating IOL (Crystalens HD) and Group B, of a dual-optic accommodating IOL (Synchrony). Distance and near visual acuities, contrast sensitivity, ocular aberrations, reading performance, and the defocus curve were evaluated over a 6-month postoperative follow-up.RESULTS: Group A comprised 27 eyes and Group B, 26 eyes. The patient age ranged from 59 to 82 years. Uncorrected and corrected distance visual acuities were significantly better in Group B (P =.13). In the defocus curve, Group B had significantly better visual acuities at several levels of defocus (P
