Accommodative intraocular lens tilting.

ABSTRACT

PURPOSE: To report an unusual complication of accommodative intraocular lens (IOL) implantation after clear lens extraction for hyperopia correction. DESIGN: Observational case report. METHOD: A 48-year-old woman underwent clear lens exchange for the correction of moderate hyperopia. A Crystalens Model AT-45 Accommodating Posterior Chamber IOL (AT-45 IOL) was implanted to allow optimal distance and near vision. At the 3-week follow-up appointment, she complained of monocular diplopia. Ocular examination showed an increased astigmatism, causing decreased visual acuity. Scheimpflug Pentacam Image and Wave Front Analysis supported the diagnosis of IOL tilting. RESULTS: IOL repositioning was unsuccessful because of fibrosis of the haptics. It was necessary to replace AT 45 IOL with a monofocal acrylic sulcus-fixated IOL. CONCLUSION: Control of capsular fibrosis should be a major concern, especially in this type of IOL. Accommodating IOL exchange appears to be a safe alternative to manage this complication.
