Ocular damage after implantation of oversized minus power anterior chamber intraocular lenses in myopic phakic eyes: case reports.

BACKGROUND: Positioning in the iridocorneal angle is one of the factors determining long-term tolerance of anterior chamber intraocular lenses (IOLs). This problem has again become topical with the use of myopic IOLs with angular supports.
METHODS: The authors describe three eyes illustrating the possible complications resulting from the insertion of oversized minus power anterior chamber implants in myopic phakic eyes.
RESULTS: The complications developed early or late after surgery. They consisted mainly of inflammatory reactions, stable or progressive pupillary deformation, and adherence of the iris to the implant.
CONCLUSIONS: In myopic phakic eyes, the insertion of incorrectly sized IOLs with angular supports may cause complications which have already been reported for anterior chamber implants in aphakic eyes. Haptic flexibility does not always make up for incorrect sizing due to imprecise preoperative evaluation of iridocorneal angle diameter.
