Dislocated Intraocular Lens

An intraocular lens (IOL) is a lens placed into the eye usually during cataract surgery.  Often this lens is placed into a structure in the front of the eye called the capsular bag.  This bag supports the lens in a natural position within the eye.  Sometimes this capsular bag might be damaged during cataract surgery, from trauma, as a result of age, or a genetic predisposition.  If the capsular bag weakens, the IOL can shift and dislocate.  This can cause extremely blurred or even double vision.

What are the treatment options for a dislocated IOL?

Not all dislocated IOLs require treatment.  If the dislocation is minor and the IOL is still covering the central visual axis, symptoms can be minimal to non-existent and observation might be the best option.  

If the dislocation progresses or is more severe, surgery might be necessary.  No two dislocations are the same, and there are many different surgical approaches.  Having a surgeon who is well versed in the various methods for rescuing and repositioning the existing IOL or possibly removing the IOL and replacing it with a new one is essential.  At Washington Retina we are trained in the most up to date methods including scleral fixated IOLs with either gore-tex suture or Yamane technique, sulcus IOL placement, or anterior chamber IOL placement.  

What can I expect after surgery?

Vision recovery will take longer than after the initial cataract surgery, but vision often improves significantly within a few weeks.  Your glasses prescription might also change, as the calculations for correct lens power are much less accurate than with uncomplicated cataract surgery.
