Las mediciones precisas de la córnea son cruciales en la cirugía refractiva corneal para asegurar resultados exitosos.

Las lentes de contacto blandas pueden dar lugar a cambios en la curvatura y de elevación de la estructura de la córnea.

La FDA de Estados Unidos (Food and Drug Administration) marcó unas directrices preoperatorias en las que se  recomendaba que antes de realizar el estudio de Cirugía Refractiva  los usuarios de lentes de contacto deben suspender el uso de las mismas al menos dos semanas antes del examen preoperatorio.

Pues recientemente se ha publicado un estudio en la revista: Contact Lens & Anterior Eye, donde se intenta evaluar cual es el tiempo óptimo de suspensión de las lentes de contacto blandas previo al estudio de cirugía refractiva.

Métodos

Análisis de datos retrospectivos , entre un grupo de usuarios de lentes de contacto blandas (n = 45 ), y un grupo de control de No usuarios de lentes de contacto (n = 45 ) .

Posteriormente se midieron parámetros de curvatura de la córnea utilizando el Topógrafo corneal Pentacam ( Oculus , Alemania ) , antes y tras dos semanas de cese de uso de las lentes de contacto.
Resultados

Los resultados que se obtuvieron es que no hay diferencias significativas en la queratometría o el radio de curvatura sagital entre ambos grupos antes o después del cese de uso de las mismas.

Conclusiones

Dos semanas de cese de uso de lentes de contacto blandas parece más que suficiente para la resolución de los cambios de curvatura de la córnea.
