ABSTRACT
CASE REPORT: Case 1: An 82-year-old man who underwent an uncomplicated phacoemulsification and IOL implantation (Tecnis Z 9000 lens) in his right eye under topical anaesthesia. Surgery lasted 14 minutes. Case 2: A 60-year-old woman with bilateral advanced primary open angle glaucoma who underwent an uncomplicated phacoemulsification and IOL implantation (Tecnis Z 9000 lens) in her right eye under peribulbar anaesthesia. Surgery lasted 36 minutes. One month after surgery both patients noted a para-central scotoma and impaired vision. Fluorescein angiography in both cases revealed retinal pigment epithelial changes compatible with intra-operative light-induced maculopathy. DISCUSSION: Light-induced maculopathy has been reported following cataract surgery. Whether physical properties of these new polysiloxane lenses contribute to retinal susceptibility to phototoxicity under certain light conditions needs to be elucidated.

Casos clínicos:Caso 1: varón de 82 años intervenido de catarata mediante facoemulsificación e implante de lente Tecnis® Z 9000 en su ojo derecho (OD), bajo anestesia tópica. La duración de la cirugía fue de 14 minutos sin complicaciones.Caso 2: mujer de 60 años con glaucoma primario de ángulo abierto (GPAA) bilateral avanzado, intervenida sin complicaciones de catarata mediante facoemulsificación e implante de lente Tecnis® Z 9000 en su ojo derecho, bajo anestesia peribulbar. La duración de la cirugía fue de 36 minutos.Al mes de la cirugía ambos pacientes evidenciaron escotoma paracentral inferior y escasa mejora de la agudeza visual (AV). La angiografía fluoresceínica (AGF) de ambos casos reveló cambios en el epitelio pigmentario de la retina compatibles con un posible fototraumatismo macular intraoperatorio.Discusión: La maculopatía por fototoxicidad es una complicación descrita tras cirugía de catarata.El que las propiedades físicas de estas nuevas lentes de polisiloxano favorezcan el fototraumatismo retiniano en determinadas condiciones lumínicas han de ser aclaradas (AU)
