术后3个月未矫正的单眼/双眼视力效果对比

(未矫正远距离视力= UDVA; 未矫正近距离视力= UNVA; 未矫正中距离视力= UIVA)

摘要

【背景】

对比单眼植入,评估双眼植入三焦点晶体后在同样视力距离内的远中近视力结果。

【方法】

对50名患者100只眼进行双眼蔡司三焦点植入,单眼术前术后三个月及双眼术后三个月全套眼视光检查,包括双眼在未矫正远视力,最佳矫正远视力,未矫正中视力及未矫正近视力,角膜曲率及验光。

【结果】

50名患者平均年龄59.28岁(44-79之间),检查结果显示在UDVA, UIVA, UNVA 及 CDVA均有显著提升,相比较单眼,双眼植入后有令人满意的显著进步(UDVA p = 0.036; UIVA p < 0.0001; UNVA p = 0.001)。术后验光86%的患者屈光结果在± 0.50D。

HIGHLIGHTS
√ Significant improvement of uncorrected distance, intermediate and near visual acuity after surgery;

√ Good contrast sensitivity: Good levels of contrast sensitivity;

√ Low PCO-rate: No serious adverse events, no PCO;

√ Good refractive predictability: Predictable and stable results for correcting astigmatism during cataract surgery andgood refractive predictability for the postoperative sphere and cylinder;

√ Stability of the corneal optics after surgery due to MICS;

√ Low induction of aberrations with the implantation;

√ Effective restoration of the visual function with the associated high levels of visual quality and QoL;

Abstract

【MBACKGROUND】

To evaluate binocular visual outcome for near, intermediate and distance compared to monocular visual outcome at the same distances in patients implanted with a diffractive trifocal intraocular lens (IOL).

【METHODS】

The study comprised of 100 eyes of 50 patients that underwent bilateral refractive lens exchange or cataract surgery with implantation of a multifocal diffractive IOL (AT LISA tri 839MP, Carl Zeiss Meditec, Germany). A complete ophthalmological examination was performed preoperatively and 3 month postoperatively. The main outcome measures were monocular and binocular uncorrected distance (UDVA), corrected distance (CDVA), uncorrected intermediate (UIVA), and uncorrected near visual acuities (UNVA), keratometry, and manifest refraction.

【RESULTS】

The mean age was 59.28 years ± 9.6 [SD] (range 44–79 years), respectively. There was significant improvement in UDVA, UIVA, UNVA and CDVA. Comparing the monocular results to the binocular results there was a statistical significant better binocular outcome in all distances (UDVA p = 0.036; UIVA p < 0.0001; UNVA p = 0.001). The postoperative manifest refraction was in 86 % of patients within ± 0.50 [D].
