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.
