Objective

To evaluate and compare the objective and subjective outcomes after the bilateral implantation of a diffractive bifocal and trifocal intraocular lens.

Methods

This is a case–control, single-center observational study which included 27 patients; 16 patients were implanted bilaterally with the bifocal AcrySof IQ ReSTOR+3.0D and 11 patients with the trifocal AT LISA tri 839MP. Uncorrected visual acuity at distance, intermediate, and near under mesopic and photopic conditions using ETDRS charts with 10% and 100% contrast, corrected distance visual acuity, and binocular defocus curve in photopic conditions; binocular contrast sensitivity under mesopic and photopic conditions for far and near distances were assessed. The Visual Function Questionnaire-25 questionnaire was used to assess patients' satisfaction. All the measurements were performed 6–24 months after cataract surgery.

Results

The ReSTOR group had better binocular uncorrected near visual acuity in photopic conditions with low and high contrast charts (p = 0.040 and p = 0.033, respectively), as well as in far contrast sensitivity measurement under mesopic conditions with a spatial frequency of 3 cycles per degree (p = 0.034). There was not a significant difference between the two study groups in uncorrected near, intermediate or distance vision under mesopic conditions. The AT LISA tri study group had better subjective outcomes.

Conclusion

Both intraocular lenses restore visual acuity after cataract surgery. The ReSTOR intraocular lens provides better objective outcomes than the AT LISA tri, although the latter provides better subjective outcomes. The relevance of this study is the evaluation of both objective and subjective outcomes.

双眼植入衍射双焦或三焦人工晶状体后的长期客观和主观结果。

目标

评价和比较衍射双焦和三焦人工晶状体双侧植入后的客观和主观结果。

方法

这是一项病例对照、单中心观察性研究,其中包括 27 名患者;16 名患者双侧植入双焦 AcrySof IQ ReSTOR+3.0D,11 名患者植入三焦 AT LISA tri 839MP。使用具有 10% 和 100% 对比度的 ETDRS 图表,在明视条件下使用具有 10% 和 100% 对比度的远距离、中距离和近距离的未矫正视力,以及在明视条件下的双眼散焦曲线;评估了远近距离的中视和明视条件下的双眼对比敏感度。使用视觉功能问卷 25 问卷来评估患者的满意度。所有测量均在白内障手术后 6-24 个月进行。

结果

ReSTOR 组在具有低对比度和高对比度图表(分别为p  = 0.040 和p  = 0.033)的明视条件下以及在空间频率为 3 个周期/周期的中视条件下的远对比敏感度测量中具有更好的双眼未矫正近视力度 ( p  = 0.034)。在中间视力条件下,两个研究组之间在未矫正的近、中或远视力方面没有显着差异。AT LISA tri 研究组的主观结果更好。

结论

两种人工晶状体在白内障手术后都能恢复视力。ReSTOR 人工晶状体提供比 AT LISA tri 更好的客观结果,尽管后者提供更好的主观结果。本研究的相关性是对客观和主观结果的评估。
