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. Postexchange vision was best in those eyes treated for inappropriate implant power (100%⩽20/40), intermediate in dislocation cases (83%⩽20/40), and poorest in eyes with chronic intraocular inflammation (50%⩽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.
