Intraocular lens opacification after corneal endothelial keratoplasty: electron microscopy and x-ray element spectroscopy analysis.

PURPOSE

To assess a newly recognized long-term complication of Descemet-stripping automated endothelial keratoplasty (DSAEK).

SETTING

Plymouth Royal Eye Infirmary and Plymouth Electron Microscope Centre, Plymouth, United Kingdom.

DESIGN

Retrospective case series.

METHODS

This study evaluated cases of intraocular lens (IOL) opacification that developed after uneventful DSAEK. None of the IOLs was previously known to opacify. In 1 case, the opacified IOL was explanted and analyzed using detailed light microscopy, scanning electron microscopic (SEM) analysis, and element x-ray spectroscopy.

RESULTS

In all 5 cases, the IOL was hydrophilic acrylic and the eye developed IOL anterior surface opacification 4 to 12 months after DSAEK. In 1 eye, the opacification was symptomatic; thus, an IOL exchange was performed. Light microscopy and SEM analysis of the explanted IOL confirmed opacification on the anterior surface and subsurface areas. X-ray element spectroscopy showed the granules were composed of calcium and phosphorous.

CONCLUSIONS

These cases indicate that IOL opacification after DSAEK is a late, although newly recognized, complication of endothelial keratoplasty.
