PURPOSE To compare the visual and refractive outcomes with a diffractive toric extended depth-of-focus (EDOF) intraocular lens (IOL) when both eyes are targeted for emmetropia and the nondominant eye is targeted for slight myopia. SETTING Three clinical practices, United States. DESIGN Prospective case series. METHODS Patients having routine cataract surgery with bilateral Tecnis Symfony toric EDOF IOL implantation were assigned to 1 of 2 groups. In 1 group, the nondominant eye was targeted for -0.50 diopter (D) (mini-monovision). Assessments included uncorrected monocular and binocular visual acuities (logarithm of the minimum angle of resolution) at distance (4 m), intermediate (66 cm), and near (40 cm) and the postoperative residual refractive error. RESULTS Forty patients were enrolled in each group, with 1 dropout. The mean postoperative residual refractive astigmatism was 0.25 D in both groups, with no statistically significant difference. The mean residual refractive astigmatism was 0.50 D or lower in 92% of eyes (72/78) in the mini-monovision group and 95% of eyes (74/78) in the emmetropia group 3 months postoperatively. The mini-monovision group had slightly worse uncorrected visual acuity at 4 m than the emmetropia group (0.16 versus 0.09; P = .002) but better uncorrected acuity at 40 cm (0.25 versus 0.34; P < .001). Binocular uncorrected acuity was not statistically significantly different between groups at 4 m (-0.03 versus -0.01; P = .33) or 66 cm (0.06 versus 0.04; P = .34) but was statistically significant at 40 cm (0.25 versus 0.19; P = .03). CONCLUSIONS The EDOF toric IOL provided functional distance, intermediate, and near vision. A slight monovision approach appears to improve near visual acuity.

针对非优势眼的双眼正视或轻度近视的扩展焦深复曲面人工晶状体：视觉和屈光性临床结局。

目的将双眼以正视眼为目标，非优势眼以轻度近视为目标时，使用散光复曲面扩展景深（EDOF）人工晶状体（IOL）来比较视觉和屈光结局。地点美国的三种临床实践。设计预期案例系列。方法将例行白内障常规双侧Tecnis Symfony复曲面EDOF IOL植入术的患者分为2组中的1组。在1组中，非优势眼的目标是-0.50屈光度（D）（微型单眼）。评估包括距离（4 m），中间（66 cm）和附近（40 cm）的未矫正的单眼和双眼视力（最小分辨角的对数）以及术后残余屈光不正。结果每组40例患者入组，其中1例辍学。两组术后平均残余屈光散光为0.25 D，差异无统计学意义。术后3个月，迷你单眼组的平均残余屈光散光为0.50 D或更低，正视眼组的平均残余屈光散光为0.50 D或更低，正视散瞳组的平均残余屈光散光为95％的眼睛（74/78）。小型单眼视力组在4 m时的未矫正视力比正视眼组稍差（0.16比0.09； P = 0.002），但在40 cm处的未矫正视力更好（0.25 vs 0.34； P <.001）。组之间在4 m（-0.03对-0.01; P = .33）或66 cm（0.06对0.04; P = .34）时，双眼未矫正视力在统计学上无显着差异，但在40 cm（0.25对0.19; 0.4 cm对统计学上显着P = .03）。结论EDOF复曲面人工晶状体提供了远距离，中度和近视功能。
