PURPOSE: To present 3 patients who required explantation of KAMRA inlays (AcuFocus, Inc., Irvine, CA) due to visual symptoms caused by postoperative corneal haze. METHODS: Case series. RESULTS: All patients had good near and distance vision immediately following implantation. They developed visual symptoms 3 to 6 years later. All patients reported a decline in distance vision. Two patients had hyperopic shift with flattening of the central cornea. Six months following explantation, all patients reported improvement in visual symptoms. A reversal of hyperopic shift was also observed, with improvement in corneal profiles on topography. Histopathology of the explanted inlays showed thin, acellular collagenous fibrotic membranes over the inlays with occasional chronic inflammatory cells. CONCLUSIONS: It is important for health care professionals to be made aware of this reversible complication following KAMRA inlay implantation. Long-term monitoring is recommended.
