体外光学质量测试系统对IOL光学质量评估应用的研究进展

Research progress in the application of in vitro optical quality test system for the assessment of IOL optical quality

手术是目前白内障唯一有效的治疗方法。随着生活水平的提高,人们对术后视觉质量的要求也越来越高,各种功能性人工晶状体(IOL)不断推出。体外光学质量测试系统用于新型IOL的设计和优化、IOL临床应用的前期研究,评估IOL的材料、设计、偏心量、倾斜度、旋转度、入射光波长,瞳孔直径等因素对IOL光学质量的影响,有助于医生对IOL的充分了解和正确选择。体外光学质量测试系统主要包括光学测试平台和光学设计软件,前者可对IOL进行实验测量,而后者可对IOL进行光学数值模拟。目前体外光学质量测试系统在国内应用较少,但逐渐受到关注,本文围绕常用的IOL体外光学质量测试系统及其临床应用进行综述,包括体外光学质量的测量评估指标、光学测试平台(OptiSpheric■ IOL PRO、Badal Optometer、PMTF和NIMO)的构造和光学设计软件(ZEMAX、OSLO和VirtualLab)的测量原理,二者在IOL光学质量评估方面的应用,以及体外光学测试的局限性等。

Surgery is currently the only effective treatment for cataract.As the standard of living improves,people's demand for postoperative visual quality increases,and a variety of functional artificial lenses(IOL)have been continuously introduced.The in vitro optical quality testing system is used for the design and optimization of new IOL and for the preliminary clinical study of IOL to evaluate the effects of influencing factors such as IOL material,design,decentration,tilt,rotation,incident light wavelength and pupil diameter on the optical quality of IOL.It is helpful for doctors to fully understand and correctly select IOL.In vitro optical quality test systems mainly include optical testing platform and optical design software.The former can experimentally measure IOL,while the latter can perform optical numerical simulation of IOL.In vitro optical quality test systems have received increasing attention in China in recent years.This article reviews the in vitro optical quality test system of IOL and its clinical application.This article reviews the commonly used in vitro optical quality test systems and their clinical applications,including the measurement and evaluation indicators of in vitro optical quality,the construction of optical test platforms(OptiSpheric■ IOL PRO,Badal Optometer,PMTF,and NIMO)and the measurement principles of optical design software(ZEMAX,OSLO,and VirtualLab),as well as their applications in IOL optical quality evaluation and the limitations of in vitro optical testing.
