My intraocular lens has moved out of position. How can it be treated?

When an IOL moves out of its normal position, vision may become blurry or objects may appear doubled. Treatment may involve repositioning or exchanging the lens. If there is insufficient tissue to support it, scleral fixation may be considered. The appropriate technique depends on the condition of the IOL and the structures inside the eye.
