Causes and management of posterior chamber lens displacement.
Posterior chamber lens implantation, although satisfactory in almost 95% of cases, can result in lens dislocation. Whereas serious dislocations such as the sunset and windshield-wiper syndromes are less frequent since the introduction of highly flexible loops, posterior vaulting of the pseudophakos may cause problems, eventually provoking a posterior capsule rupture and a secondary sunset syndrome. The iris-capture syndrome can be almost entirely prevented by using angulated loops. If it occurs, it can usually be corrected easily. Small decentrations as well as oblique malpositions of the pseudophakos are usually less important but should be recognized, analyzed, and prevented.
