Abstract:  Objective To discuss the clinical characteristics of intraocular lens (IOL) dislocation. Design Retrospective cases series. Participants 49 eyes (49 cases) of intraocular lens dislocation in Beijing Tongren Hospital from 2004 to 2011. Methods Clinical data of intraocular lens dislocation were reviewed retrospectively. Main Outcome Measures  Age, original disease, history of disease, position and type of intraocular lens, cause, surgical method, and complication. Results Majority of 49 cases of intraocular lens dislocation were cases with surgery of age-related cataract (46.9%) and traumatic cataract (28.6%). 6 cases with dislocation of intraocular lens with ciliary sulcus fixation happened 1 year after surgery. Majority of intraocular lenses dislocated located in vitreous body (53.1%) and “C” loop (89.8%). 75.5% of causes were original disease and surgery. Ciliary sulcus fixation or re-fixation of intraocular lens (47 eyes, 95.9%) could achieve good centration and stability of the intraocular lens. Naked vision of 0.1 or more accounted for 59.6% at 2 weeks after fixation or re-fixation. Conclusion Intraocular lens dislocation is related with original disease and surgery. Ciliary sulcus fixation of intraocular lens is an effective strategy to treat intraocular lens dislocation. But intraocular lens with ciliary sulcus fixation still happens to dislocate.
