Abstract: Late intraocular lens (IOL) dislocation is a dislocation of the IOL that occurs 3 months or more after cataract surgery and is a rare but serious complication after cataract surgery. Studies have shown that the cumulative incidence of which in 10~15 years after surgery is 0.1% to 3%, and the incidence has been increasing in recent years. Dislocation of IOL may be caused by rupture of the zonular dehiscence and contraction of the capsular bag due to a variety of factors, including pseudoexfoliation, high myopia, and trauma, etc. At present, there are a series of preventive and therapeutic measures for advanced IOL dislocation. The most common treatment methods include IOL repositioning surgery and IOL exchange surgery. The specific surgical method needs the surgeon to comprehensively evaluate the situation of IOL dislocation to decide.
