Unidentified foreign objects in the wound after clear corneal tunnel phacoemulsification.

We describe the presence of unidentified foreign objects, including small freckles and fibrillary material, in the corneal stroma seen on slitlamp biomicroscopy in 2 patients who had uneventful clear corneal tunnel phacoemulsification. Clinically, these foreign objects did not appear to affect the final visual outcome. Further study is required to explain their source, role in the wound healing, and toxicity and the behavior of metallic particles in the magnetic field in relation to magnetic resonance imaging.
