Persistent corneal fibrosis after explantation of a small-aperture corneal inlay.

The KAMRA small-aperture corneal inlay can compensate for presbyopia. A small number of complications have been reported, including glare, halos, decentration, iron deposition, compromised distance and night vision, infectious keratitis and reversal corneal haze. We describe a case of corneal fibrosis after small-aperture corneal inlay implantation and its persistence after late explantation. The postoperative period was uneventful, with good uncorrected near and distance visual acuities. Six years after implantation, the patient reported vision loss in the left eye. A slitlamp evaluation and optical coherence tomography showed stromal opacity and a stromal hyperreflective signal at the level of the small-aperture corneal inlay. The corneal inlay was removed, but persistent decreased visual acuity and fibrosis were observed even 8 months after explantation and did not respond to steroids. Long-term monitoring with multimodal imaging methods is important to detect late adverse events after small-aperture corneal inlay implantation.
