摘要
背景:在各种视觉功能中,立体视敏或感知深度的能力是最复杂的双目功能。许多出版物讨论了多焦点人工晶状体形成视网膜图像对眩光和对比敏感度的影响,但只有少数报道了多焦点人工晶状体患者的双眼视力测试结果。目的:回顾多焦人工晶状体植入术患者双眼视力的检测结果。方法:通过文献综述和PubMed、Scopus、Web of Science、Google Scholar等科学数据库进行网络检索。结果:一些报告发现,当用近加法测量时,植入单焦点人工晶状体的患者的立体视力评分明显优于植入任何一种多焦点人工晶状体的患者。当使用TNO检验进行测量时,发现屈光型多焦人工晶状体的立体视力优于衍射型多焦人工晶状体。立体视敏度评分,即使在相同类型的镜片内,使用Titmus测试明显优于使用TNO测试。结论:立体视力不受多灶性视网膜模糊的影响,而受其他原因的图像退化的影响,如微小的残余屈光不正,非常早期的眼介质混浊或干眼。多焦点人工晶状体不会比单焦点人工晶状体引起更多的功能性斜视。由于单侧多焦点人工晶状体植入术会影响立体视力,因此应尝试双侧植入术。
Stereoacuity and Multifocal Intraocular Lenses - a Systematic Review.
Background: Among various visual functions, stereoacuity, or the ability to perceive depth, is the most sophisticated binocular function. Many publications discuss the influence of retinal image formation by multifocal intraocular lenses on glare and contrast sensitivity, but only a few present results of testing binocular vision in patients with multifocal intraocular lenses.
Objective: This article is designed to review the results of testing binocular vision in patients with multifocal intraocular lenses implanted in cataract surgery.
Methods: This article was performed based on a literature review and Internet search through scientific databases such as PubMed, Scopus, Web of Science, and Google Scholar.
Results: Some reports found that patients implanted with the monofocal lens, when measured with a near addition, presented statistically significant better stereoacuity scores than those implanted with any of the multifocal intraocular lens types. When the TNO test was used for measurement, statistically significant better stereoacuity was disclosed with the refractive multifocal intraocular lens than with the diffractive-based multifocal intraocular lens design. Stereoacuity scores, even within the same types of lenses, were significantly better with the Titmus test than with the TNO test.
Conclusion: Stereoacuity is not affected by multifocality-induced retinal blur as it is by other causes of image degradation such as small residual refractive error very early opacification of ocular media or dry eye. Multifocal intraocular lenses do not cause more functional aniseikonia than would be expected with a monofocal intraocular lens. Since stereoacuity is compromised with unilateral multifocal intraocular lens implantation bilateral implantation should be attempted.
