PURPOSE: To evaluate the usefulness of ultrasound biomicroscopy in confirming intraocular lens haptic-induced ocular irritation and in the management of these patients. DESIGN: A retrospective review of patient data. METHODS: Twenty pseudophakic patients who underwent ultrasound biomicroscopy examination between May 2009 and February 2011 to confirm the clinical suspicion of misplacement of intraocular lens haptics were reviewed. Ophthalmic findings at the time of presentation and at each follow-up visit, and management of each patient, were recorded. RESULTS: Intraocular lens haptic misplacement was confirmed by ultrasound biomicroscopy in all suspected cases. In 75% of the eyes 1 haptic was embedded in the iris; it extended into the ciliary body process in 35% and into the pars plana in 10%. Focal iris thinning/atrophy was detected by ultrasound biomicroscopy in 15% of cases and focal angle closure in 25%. Intraocular lens exchange was performed in 40% of patients. The remaining 60% were kept under observation, with the addition of topical steroids and/or cycloplegics in eyes that demonstrated anterior chamber inflammation and intraocular pressure-lowering medications in eyes with persistent elevated intraocular pressure or glaucoma. CONCLUSIONS: Ultrasound biomicroscopy appears to be a valuable tool in confirming the presence of haptic-induced ocular irritation and in assisting the management of these patients.
