Fuchs’ dystrophy associated with radial keratotomy: Lamellar or perforating keratoplasty?

Abstract

Case report

A 70 year-old male patient with a history of radial keratotomy suffering from Fuchs’ dystrophy and a cataract. The patient received a two-step surgery: lens phacoemulsification and intraocular lens implant, followed by descemet stripping automated endothelial keratoplasty in both eyes, four months later. There were no complications apart from a recurrent cystoid macular edema in both eyes. The best corrected visual acuity was 20/40 both eyes, and the patient was satisfied.

Discussion

Descemet stripping automated endothelial keratoplasty may be considered as an alternative to penetrating keratoplasty in the case of endothelial dysfunction and radial keratotomy in patients with no corneal ectasia or significant stromal opacity.

Resumen

Caso clínico

Paciente de 70 años que acude con queratotomía radial, signos de distrofia de Fuchs con edema central y catarata. Se realiza cirugía en 2 tiempos: facoemulsificación e implante de lente intraocular y 4 meses después DSAEK (descemet stripping automatized endothelial keratoplasty) en ambos ojos sucesivamente sin complicaciones, salvo edema macular cistoide recurrente en ambos ojos. La agudeza visual corregida final es 20/40 en ambos ojos y el paciente se encuentra satisfecho.

Discusión

Ante coexistencia de queratotomía radial y disfunción endotelial, la DSAEK constituye una alternativa a la queratoplastia penetrante si no se detecta ectasia corneal ni opacidad estromal significativa.
