RESUMO
Cataract is one of the most common causes of vision loss and even blindness in patients, and surgery is a proven and effective treatment option. Traditional cataract surgery for vision loss has increasingly given way to refractive cataract surgery as science and technology have progressed. There are also a variety of refractive intraocular lenses on the market place. Patients are increasingly accepting and recognizing multifocal intraocular lens(MIOL)as an alternative to traditional single focus intraocular lens(SIOL). Through classification and listing, the existing MIOL are discussed in this article, as well as the features of different types of MIOL and techniques for evaluating the clinical impacts of patients after surgery, so as to provide references for ophthalmologists.
