Toric intraocular lenses (T-IOLs) may lose their optical quality if they are not correctly positioned inside the capsular bag once implanted. In this work, T-IOLs with cylinder powers of +1.50, +4.50 and +7.50 D and differing degrees of spherical aberration have been designed, manufactured and tested using a commercial optical bench that complies with the requirements of standard ISO 11979-2. Moreover, the effect of tilt and rotation on optical quality was assessed by means of numerical ray tracing on an astigmatic eye model, while the effect of decentration was evaluated numerically and experimentally.
植入后，如果散光人工晶状体（T-IOL）在囊袋内未正确定位，其光学质量可能会下降。在这项工作中，设计、制造并测试了柱镜度数分别为+1.50 D、+4.50 D和+7.50 D且具有不同程度球差的散光人工晶状体，使用的是符合ISO 11979-2标准要求的商用光学平台。此外，通过在散光眼模型上进行数值光线追迹评估倾斜和旋转对光学质量的影响，而通过数值和实验评估偏心对光学质量的影响。
