目的评价超声乳化白内障摘出联合散光矫正型多焦点人工晶状体(ART IOL)植入术后的视觉质量,并与非散光矫正型多焦点IOL(ReSTOR IOL)进行比较。
方法采用队列研究方法,纳入2017年1月至2018年1月于天津医科大学眼科医院行超声乳化白内障摘出联合ART IOL植入术的患者39例50眼和联合ReSTOR IOL植入术的患者32例41眼,分别作为ART组和ReSTOR组。对比2个组患眼术后3个月时的裸眼远视力(UDVA)、裸眼中视力(UIVA)、裸眼近视力(UNVA)、最佳矫正远视力(CDVA)、显然验光、离焦曲线、对比敏感度(CS)、调制传递函数截止频率、二维斯特列尔比(SR)、客观散射指数、不同对比度下OQAS值(OV 100%、OV 20%、OV 9%)、总像差、总低阶像差、总高阶像差、球差、彗差和三叶草像差。
结果术后3个月,ART组和ReSTOR组的UDVA分别为(0.07±0.09)LogMAR和(0.09±0.12)LogMAR,CDVA分别为(-0.01±0.07)LogMAR和(-0.01±0.07)LogMAR,UIVA分别为(0.23±0.11)LogMAR和(0.22±0.13)LogMAR,UNVA分别为(0.11±0.15)LogMAR和(0.06±0.11)LogMAR。ReSTOR组的UNVA略优于ART组,差异有统计学意义( t=2.085, P=0.040)。ART组和ReSTOR组的平均焦点深度分别为(4.12±0.79)D和(4.24±0.95)D。ART组术后残余散光为(0.32±0.31)D,较术前角膜散光的(1.27±0.40)D显著降低,差异有统计学意义( t=13.209, P<0.001)。ART组在明视6、12和18 c/d,明视眩光12和18 c/d,以及暗视3、6和12 c/d空间频率时的CS值略低于ReSTOR组,差异均有统计学意义(均 P<0.05),但不具有临床意义。ART组的SR和OV 20%值分别为0.14±0.05和0.55±0.24,略低于ReSTOR组的0.17±0.06和0.66±0.29,差异均有统计学意义( t=-2.012, P=0.048; t=-2.557, P=0.043)。ART组在5 mm瞳孔直径下的总像差和彗差分别为0.88(0.59,1.13)μm和0.21(0.13,0.30)μm,高于ReSTOR组的0.58(0.47,0.74)μm和0.10(0.08,0.21)μm,差异均有统计学意义( Z=-2.073, P=0.038; Z=-2.101, P=0.036)。
结论超声乳化白内障摘出联合ART IOL植入可以在矫正术前角膜散光的同时为患者提供良好的全程视力和主客观视觉质量,但暗光下或中低空间频率的解析能力略弱于ReSTOR IOL植入眼。
ObjectiveTo evaluate and compare the postoperative visual quality after phacoemulsification combined with toric (ART) and non-toric (ReSTOR) multifocal intraocular lens (IOL) implantation.
MethodsA cohort study was conducted.Thirty-nine cataract patients (50 eyes) who underwent phacoemulsification combined with ART IOL implantation were enrolled as ART group, and 32 patients (41 eyes) who received ReSTOR IOL implantation were enrolled as ReSTOR group in Tianjin Medical University Eye Hospital from January 2017 to January 2018.Three months after surgery, the uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA), manifest refraction, defocus curve, contrast sensitivity (CS), modulation transfer function cutoff, Strehl2D ratio (SR), objective scattering index, OQAS values under 100%, 20%, 9% contrasts (OV 100%, OV 20%, OV 9%), total aberrations, total lower-order aberrations, total higher-order aberrations, spherical aberrations, coma and trefoil aberrations of the two groups were tested and compared.The study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Tianjin Medical University Eye Hospital (No.2019KY[L]-04). Written informed consent was obtained from each subject prior to entering the cohort.
ResultsUDVA at 3 months after surgery was (0.07±0.09)LogMAR and (0.09±0.12)LogMAR in ART group and ReSTOR group, and CDVA was (-0.01±0.07)LogMAR and (-0.01±0.07)LogMAR, and UIVA was (0.23±0.11)LogMAR and (0.22±0.13)LogMAR, and UNVA was (0.11±0.15)LogMAR and (0.06±0.11)LogMAR.UNVA was slightly better in ReSTOR group than ART group, and the difference was statistically significant ( t=2.085, P=0.040). The mean depth of focus was (4.12±0.79)D in ART group and (4.24±0.95)D in ReSTOR group.The postoperative residual astigmatism (0.32±0.31)D was significantly lower than preoperative corneal astigmatism (1.27±0.40)D in ART group ( t=13.209, P<0.001). CS values at 6, 12, and 18 c/d under photopic without glare, 12 and 18 c/d under photopic with glare, 3, 6, and 12 c/d under scotopic without glare in ART group were slightly lower than those in ReSTOR group, showing statistically significant differences (all at P<0.05) without clinical significance.SR and OV 20% values in ART group were 0.14±0.05 and 0.55±0.24, which were slightly lower than 0.17±0.06 and 0.66±0.29 in ReSTOR group, with statistically significant differences ( t=-2.012, P=0.048; t=-2.557, P=0.043). Total aberrations and coma aberration under 5 mm pupil diameter in ART group were 0.88(0.59, 1.13)μm and 0.21(0.13, 0.30)μm, which were higher than 0.58(0.47, 0.74)μm and 0.10(0.08, 0.21)μm in ReSTOR group, showing statistically significant differences ( Z=-2.073, P=0.038; Z=-2.101, P=0.036).
ConclusionsCataract phacoemulsification combined with ART IOL implantation can provide good vision and visual quality while correcting preoperative corneal astigmatism, and the resolution in dim light or low to medium spatial frequencies is slightly weaker than eyes implanted with ReSTOR IOL.
