title: Intraocular lens implant exchanges.
abstract: We reviewed 23 consecutive cases of intraocular lens implant exchange. Lens dislocation (26%) and chronic intraocular inflammation (26%) were the most frequent indications for lens exchange. Post-exchange vision was best in those eyes treated for inappropriate implant power (100% less than or equal to 20/40), intermediate in dislocation cases (83% less than or equal to 20/40), and poorest in eyes with chronic intraocular inflammation (50% less than or equal to 20/40), even though the inflammation usually improved. Eighty-three percent of the total cases remained within one line of the pre-exchange visual acuity.
