Abstract
The occurrence of multifocal intraocular lens (MIOL) is known as an important period in the development of cataract surgery, which can provide a simultaneous vision without the use of spectacles or contact lenses. However, in the current stage, MIOL implantation may also lead to decreased visual acuity and increased risk of photic phenomena, thus in some instance a second procedure to exchange the MIOL is necessary. Optimizing visual outcomes of MIOL implantation and controlling adverse effects has become the focus for ophthalmologists. In the future, a more remarkable, flexible and high cost-effective intraocular lens (IOL), which can mimic human natural crystalline lens, should emerge. (Chin J Ophthalmol, 2017, 53: 244-248).
