When does an intraocular lens need to be exchanged?
IOL exchange may be considered if a lens becomes dislocated, if its power is significantly different from what the eye needs, or if substantial lens-related symptoms persist despite treatment of other causes. Because an exchange procedure carries its own risks, we carefully weigh the expected benefits against the complexity and potential complications of surgery.
