Abstract：
UNASSIGNED: To determine if the changes in stereoacuity and aniseikonia, following bilateral implantation of presbyopia correcting intraocular lenses could be predicted from preoperative measurements of higher order aberrations (HOAs), axial lengths (AL), refractive errors (RE) and corrected visual acuities (CVAs).
UNASSIGNED: Stereoacuity (Randot tests, @6m & 40cm, in steps of 20 arcsecs\") vertical and horizontal aniseikonia (Awaya test @6m, in steps of 1%) with best correction and HOAs (Shack-Hartmann aberrometer) were measured before, 3 and 6 months after uncomplicated bilateral phacoemulsification. Twenty patients (I) underwent a mix-and-match procedure (Tecnis MF, ZKB00 in one eye and ZLB00 in the other), 17 (II) were implanted with a trifocal (AT LISA 839 triMP) and 18 (III) with a one-piece diffractive (Synergy OU) intraocular lens. The resultant aniseikonia (AR) of vertical and horizontal pairs of aniseikonia measurements was calculated using the Pythagorean theorem. Twenty untreated age/gender matched cases were recruited as controls (IV).
UNASSIGNED: The key results (p < 0.001) were a) stereoacuity at distance (SAD) and near (SAN) improved, AR reduced in groups I, II & III remaining unchanged in group IV; b) some significant intergroup differences in SAD, SAN & AR were detected at postop; c) at 6 months postop, changes (Δ=pre- minus postoperative value) correlated with preoperative values (x). Linear regression revealed, I ΔSAD=0.66x-57.47 [0.832, ±66.4], ΔSAN=0.96x-34.59 [0.821, ±16.9], ΔAR=0.93AR-2.12 [0.795, ±1.4] II ΔSAD=0.79x-62.91 [0.916, ±38.1], ΔSAN=0.96x-31.49 [0.892, ±8.0], ΔAR=0.91AR-0.91 [0.839, ±1.3] III ΔSAD=0.67x-35.50 [0.991, ±23.7], ΔSAN=0.88x-38.51[0.988, ±10.6], ΔAR=0.86AR-0.96 [0.900, ±1.3]. Figures in parentheses are the corresponding rs and ±limits of agreement between actual and estimated values. Definitive overarching associations connecting interocular differences in HOAs, AL, RE, and CVAs with SAD, SAN and AR were not found.
UNASSIGNED: Changes in stereoacuity and aniseikonia can be predicted using preoperative values. ΔSAN can be predicted within ±1, and ΔAR within ±2, scale divisions. In group III ΔSAD can be predicted within ±1, and in group I ±3, scale divisions.

摘要：
■为了确定立体敏锐度和aniseikonia的变化，在双侧植入老花眼矫正人工晶状体后，可以通过术前测量高阶像差（HOAs）来预测，轴向长度（AL），屈光不正(RE)和矫正视力(CVA)。
■立体灵敏度(Randot测试，@6m&40cm,以20弧秒的步长）垂直和水平aniseikonia（Awaya测试@6m，以1％的步长）进行最佳校正，并在之前测量HOA（Shack-Hartmann像差仪），无并发症双侧超声乳化术后3个月和6个月。20名患者(I)接受了混合搭配手术(TecnisMF，一只眼睛中的ZKB00和另一只眼睛中的ZLB00），17（II）植入了三焦点（ATLISA839三MP）和18（III）植入了一件式衍射（SynergyOU）人工晶状体。使用毕达哥拉斯定理计算了垂直和水平对aniseikonia测量结果的aniseikonia（AR）。招募20例年龄/性别匹配的未治疗病例作为对照(IV)。
■关键结果（p<0.001）是a）远距离（SAD）和近距离（SAN）改善的立体敏锐度，第一组的AR降低，II和III在IV组中保持不变；b)SAD的一些显著组间差异，SAN和AR在postop检测到；c)在术后6个月时，变化（Δ=术前减去术后值）与术前值（x）相关。线性回归显示，IΔSAD=0.66x-57.47[0.832，±66.4]，ΔSAN=0.96x-34.59[0.821,±16.9],ΔAR=0.93AR-2.12[0.795,±1.4]IIΔSAD=0.79x-62.91[0.916,±38.1],ΔSAN=0.96x-31.49[0.892,±8.0],ΔAR=0.91AR-0.91[0.839,±1.3]IIIΔSAD=0.67x-35.50[0.991,±23.7],ΔSAN=0.88x-38.51[0.988,±10.6],ΔAR=0.86AR-0.96[0.900,±1.3]。括号中的数字是实际值和估计值之间的相应rs和±一致极限。连接HOA中眼间差异的决定性总体关联，AL,RE,和带有SAD的CVAs，没有发现SAN和AR。
■可以使用术前值预测立体敏锐度和aniseikonia的变化。ΔSAN可以预测在±1范围内，ΔAR可以预测在±2范围内。在第III组中，ΔSAD可以预测在±1范围内，在第I组±3范围内。
