A 61-year-old male developed recurrent anterior uveitis over a period of 8 months after an uncomplicated phacoemulsification and posterior chamber intraocular lens implantation surgery. This was subsequently found to be due to a retained lens fragment in the anterior segment, with complete resolution following surgical extraction of the fragment. To our knowledge, this is the first report of recurrent anterior uveitis attributable to a retained lens fragment following uncomplicated cataract surgery, and the diagnosis should be considered in a pseudophakic patient presenting with recurrent episodes of anterior uveitis.
