Cataract surgery is one of the most common and successful surgical procedures performed today. Over the past decade, the risk of severe complications has decreased with advances in surgical instruments and techniques. In the procedure, the cataract (cloudy lens) is removed, and a clear intra-ocular (in-the-eye) lens is placed. Rare complications include intra-ocular lens (IOL) dislocation, where the lens moves out of place.
The most common symptom of a dislocated IOL is a change in vision. The degree to which vision is affected will depend on the severity of the dislocation.
