But de l'étude

To determine incidence and to document risk factors for Intra Ocular Lens (IOL) calcification after pseudophakic endothelial keratoplasty

Méthode

We retrospectively studied 2,700 consecutive penetrating, anterior lamellar and endothelial keratoplasties carried out between December 1992 and June 2022 in National Eye Hospital, Paris, France

Résultats

Out of 588 endothelial keratoplasty procedures, 576 eyes were pseudophakic at the end of surgery. 14 cases of IOL calcification were observed during follow-up. The cumulative incidence of IOL calcification after endothelial keratoplasty was 4.5+1.3% at 60 months. IOL material (p<0.000001) and use of SF6 for anterior chamber tamponade (p=0.001) were significantly and independently associated with the cumulative incidence of IOL calcification.

Conclusions

The incidence of IOL calcifications seems to be around 5%. Ophthalmologists should avoid hydrophilic acrylic IOLs in patients with endothelial disorders. When the patient already has a hydrophilic IOL, SF6 should be avoid. The only effective treatment is IOL exchange.
