PURPOSE
To compare intraindividual differences in visual performance of a monofocal and enhanced monofocal intraocular lens (IOL) of the same platform.
DESIGN
Prospective, interventional, fellow-eye comparison clinical study.
METHODS
In total, 55 patients (110 eyes) with bilateral age-related cataract were enrolled. All patients received a monofocal ZCB00 IOL in the dominant and an enhanced monofocal Eyhance ICB00 IOL in the nondominant eye. After 2 to 4 months, monocular best-corrected distant visual acuity (BCDVA), distance-corrected intermediate visual acuity (DCIVA), distance-corrected near visual acuity (DCNVA), contrast visual acuity, monocular defocus curves, internal higher-order aberrations (HOAs) and spherical aberrations (SA), decentration, and tilt were compared.
RESULTS
The monocular mean BCDVA, DCIVA at 80 cm and 66 cm, and DCNVA were -0.03 ± 0.07, 0.24 ± 0.12, 0.32 ± 0.13, and 0.50 ± 0.13 logarithm of the minimum angle of resolution for the enhanced ICB00 and -0.06 ± 0.06 (P = .014), 0.30 ± 0.11 (P = .005), 0.38 ± 0.12 (P = .004), and 0.55 ± 0.14 (P = .034) logarithm of the minimum angle of resolution for the ZCB00, respectively. Internal HOAs (P = .001) and negative SA (P < .001) were increased with the ICB00 at 3 mm and comparable at 5 mm (P > .05). Contrast acuity, tilt, and decentration were similar (P > .05).
CONCLUSIONS
Significantly increased monocular DCIVA at 80 cm and 66 cm and DCNVA at 40 cm were observed with the enhanced ICB00 IOL, and the ZCB00 IOL demonstrated better BCDVA. This would result in a mean gain of 2 to 3 Early Treatment of Diabetic Retinopathy Study letters at near and intermediate distance. Monocular defocus curves displayed highest differences of 5 Early Treatment of Diabetic Retinopathy Study letters at -1.25 diopters (D) and -1.50 D levels of defocus and a depth of focus of 1.23 D for the ICB00 IOL and 0.94 D for the ZCB00 IOL. Decentration, tilt, and HOAs were generally low.
目的
比较相同平台的单焦点和增强型单焦点人工晶状体（IOL）的个体内视觉性能差异。
设计
前瞻性、干预性、对侧眼比较临床研究。
方法
共纳入 55 名（110 只眼）双侧年龄相关性白内障患者。所有患者均在优势眼植入单焦点 ZCB00 IOL，在非优势眼植入增强型单焦点 Eyhance ICB00 IOL。2 至 4 个月后，比较单眼最佳矫正远视力（BCDVA）、远距矫正中间视力（DCIVA）、远距矫正近视力（DCNVA）、对比视力、单眼离焦曲线、内部高阶像差（HOAs）和球差、偏心距和倾斜度。
结果
增强型 ICB00 的单眼平均 BCDVA、80cm 和 66cm 处的 DCIVA 以及 DCNVA 分别为-0.03±0.07、0.24±0.12、0.32±0.13 和 0.50±0.13 对数最小角分辨率，而 ZCB00 分别为-0.06±0.06（P=0.014）、0.30±0.11（P=0.005）、0.38±0.12（P=0.004）和 0.55±0.14 对数最小角分辨率。3mm 时 ICB00 增加了内部 HOAs（P=0.001）和负球差（P<0.001），而 5mm 时两者相似（P>0.05）。对比视力、倾斜度和偏心距相似（P>0.05）。
结论
增强型 ICB00 可显著提高单眼 80cm 和 66cm 处的 DCIVA 和 40cm 处的 DCNVA，而 ZCB00 IOL 则显示出更好的 BCDVA。这将导致近和中距离的平均增益为 2 到 3 个早期糖尿病性视网膜病变治疗研究字母。单眼离焦曲线在-1.25 屈光度（D）和-1.50 D 水平的离焦时显示出最大的差异为 5 个早期糖尿病性视网膜病变治疗研究字母，而 ICB00 IOL 的焦深为 1.23D，ZCB00 IOL 的焦深为 0.94D。偏心距、倾斜度和 HOAs 通常较低。
