Several clinical techniques have been described to evaluate visual performance and optical quality with intraocular lenses (IOL). However, subjective refraction remains one of the most important methods for assessing post-surgery results, taking decisions about retreatments, advanced spectacle prescription and the refinement of the constant for the formula used in the IOL power calculation. Beyond clinical refraction, defocus curve measurement has been described as a complementary tool for assessing visual performance and taking clinical decisions. However, to date, there are no clinical guidelines or evidence-based protocols published in the scientific literature recommended for pseudophakic patients implanted with either monofocal or multifocal IOLs. This narrative review highlights the importance of clinical refraction in pseudophakic eyes, its utility in the decision of different types of IOL implantation, and describes a clinical refraction protocol for eyes implanted with monofocal and multifocal IOLs.
已经描述了几种临床技术来评估眼内透镜（IOL）的视觉性能和光学质量。然而，主观验光仍然是评估手术后结果、决定是否进行再次治疗、制定高级眼镜处方以及改进用于 IOL 功率计算公式常数的最重要方法之一。除了临床验光外，离焦曲线测量已被描述为评估视觉性能和做出临床决策的补充工具。然而，迄今为止，在科学文献中，没有针对植入单焦点或多焦点 IOL 的假晶状体患者的临床指南或基于证据的推荐方案。本叙述性综述强调了假晶状体眼中临床验光的重要性，以及它在不同类型的 IOL 植入决策中的实用性，并描述了用于植入单焦点和多焦点 IOL 的临床验光方案。
