Abstract:

Phacoemulsification with intraocular lens (IOL) implantation for cataract is the most common surgery of the ophthalmology. As a lower incidence postoperative complication,the IOL may need to be replaced if the IOL opacification is serious. There has been no certain conclusion for the causes of IOL opacification yet. The opacification of IOL may be related to itself, such as materials，manufacture and packaging. Surgical operation or intraoperative use of viscoelastic, and patient’s own factors such as systemic disease or special metabolic state maybe the causes of IOL apacification.(Int Rev Ophthalmol, 2019, 43:  323-327)
