To evaluate visual outcomes at different distances (near, intermediate, and far), depth of focus, optical quality, quantitative dysphotopsia, and patient satisfaction in two groups.
The extended depth of focus (EDOF) only group (n = 40 eyes) was implanted bilaterally with an EDOF intraocular lens (IOL) and the mixed group (n = 40 eyes) was implanted with the same EDOF IOL in the dominant eye and a trifocal IOL in the fellow eye. At the 3-month postoperative visit, refractive outcomes and monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance visual acuities for far UDVA, CDVA, distance-corrected intermediate visual acuity (DCIVA) at 80 cm, uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA) at 40 cm, and binocular defocus curve were evaluated.
The mean spherical equivalent (SE) 3 months postoperatively was -0.16 ± 0.41 diopters (D) in the EDOF only group and -0.39 ± 0.63 D in the mixed group. In the EDOF only group, binocular visual acuities were: UDVA = -0.04 ± 0.07 logMAR (20/18); CDVA = -0.04 ± 0.06 logMAR (20/18); DCIVA (80 cm) = 0.07 ± 0.19 logMAR (20/23); DCNVA (40 cm) = 0.32 ± 0.15 logMAR (20/42); and UNVA (40 cm) = 0.24 ± 0.17 logMAR (20/35). In the mixed group, binocular visual acuities were: UDVA = 0.03 ± 0.09 logMAR (20/21) (P = .08); CDVA = -0.01 ± 0.07 logMAR (20/20) (P = .25); DCIVA (80 cm) = 0.24 ± 0.23 logMAR (20/35) (P = .08); DCNVA (40 cm) = 0.19 ± 0.07 logMAR (20/31) (P = .03); and UNVA (40 cm) = 0.18 ± 0.10 logMAR (20/30) (P = .37).
Effective restoration of visual acuity was demonstrated in both groups, with high levels of visual quality and patient satisfaction. Better results in near visual acuity were demonstrated in the mixed group. [J Refract Surg. 2019;35(7):408-416.].
评估两组患者不同距离(近、中、远)、景深、光质量、定量畏光和患者满意度的视觉效果。
在 80cm 处的无矫正近视力(UNVA)、无矫正远视力(UDVA)、远视力矫正(CDVA)、矫正距离中间视力(DCIVA)、40cm 处的矫正近视力(DCNVA)、双眼散焦曲线。
术后 3 个月,仅 EDOF 组的平均等效球镜(SE)为-0.16±0.41 屈光度(D),混合组为-0.39±0.63 D。在 EDOF 组中,双眼视力为:UDVA=-0.04±0.07 对数视力(20/18);CDVA=-0.04±0.06 对数视力(20/18);DCIVA(80cm)=0.07±0.19 对数视力(20/23);DCNVA(40cm)=0.32±0.15 对数视力(20/42);UNVA(40cm)=0.24±0.17 对数视力(20/35)。在混合组中,双眼视力分别为:UDVA=0.03±0.09 对数视力(20/21)(P=0.08);CDVA=-0.01±0.07 对数视力(20/20)(P=0.25);DCIVA(80cm)=0.24±0.23 对数视力(20/35)(P=0.08);DCNVA(40cm)=0.19±0.07 对数视力(20/31)(P=0.03);UNVA(40cm)=0.18±0.10 对数视力(20/30)(P=0.37)。
两组均有效恢复了视力,具有较高的视觉质量和患者满意度。混合组在近视力方面的结果更好。
