Displacement of the crystalline lens from its normal position in the eye. Lens dislocation is almost always caused by an injury that ruptures the fibres connecting the lens to the ciliary body. In Marfan’s syndrome, these fibres are particularly weak and lens dislocation is common. A dislocated lens may produce severe visual distortion or double vision, and sometimes causes a form of glaucoma if drainage of fluid from the front of the eye is affected. If glaucoma is severe, the lens may need to be removed. (See also aphakia.)
