Late in-the-bag dislocation of IOL bag complex:Mechanisms in etiology and risk factors / 眼科新进展

ABSTRACT

Late in-the-bag dislocation of intraocular lens bag complex is a rare but potential complication after cataract surgery,which can affect the quality of patients'life seriously,and usually need surgical treatment.People are paying more attention to this complication,because it has been reported with increasing frequency in recent years.This complication may present after a long time frame.There is a research showing that the interval between cataract surgery and the dislocation was 10.9 years.The cumulative risk of IOL dislocation at 10 years,20 years,and 25 years after cataract extraction was 0.1％,0.7％,and 1.7％ respectively.Late in-the-bag IOL dislocation is a result of progressive zonular dehiscence up to many years after cataract surgery,and its genesis is multifactorial.This article reviews the incidence,possible mechanism and risk factors of late in-the-bag IOL dislocation.
