2. Purpose
To report ultrasound biomicroscopic findings in a case of late-onset anterior uveitis associated with decentration of a Morcher aniridia intraocular lens (IOL) implant.

3. Methods
A 62-year-old man, status post bilateral penetrating keratoplasty for Fuchs corneal endothelial dystrophy, sustained a traumatic graft dehiscence with loss of iris tissue in his right eye. He subsequently underwent placement of a Morcher aniridia IOL and repeat penetrating keratoplasty in his right eye in He presented 2.5 years later with a two-week history of redness, pain, and light sensitivity in the right eye. Examination was remarkable for anterior uveitis and temporal decentration of the Morcher implant.

4. Results
Ultrasound biomicroscopy was performed to confirm a clinical suspicion that the temporally displaced Morcher aniridia implant may be contacting the ciliary body. Review of the images confirmed implant migration and ciliary body touch (Figure 1).

6. Conclusion
Persistent intraocular inflammation is a known potential complication of black iris diaphragm aniridia IOL implantation.1 Late development of intraocular inflammation after placement of an aniridia IOL has also been reported, but is less common.2 To our knowledge, this is the first report of ultrasound biomicroscopic findings providing evidence for aniridia IOL implant decentration and ciliary body chafing as a potential etiology of late-onset anterior uveitis.
