dc.description.abstractEl objetivo de esta monografía fue brindar la información necesaria para comprender e identificar la ectasia corneal postquirúrgica refractiva y su progresión mediante el Pentacam. Esta monografía se basó en la investigación bibliográfica en bases de datos en idioma inglés, español, portugués y ruso utilizando tesauros, operadores booleanos y truncadores como estrategia de búsqueda. Se definió la progresión de la ectasia como un cambio constante de al menos dos parámetros como el empinamiento de la superficie corneal anterior, la posterior o el adelgazamiento y/o aumento en la tasa de cambio del espesor corneal. La ectasia corneal postquirúrgica se define como un encorvamiento en topografía de 5 D o más en comparación con el aspecto postoperatorio, pérdida de ≥ 2 líneas de Snellen de agudeza visual no corregida y un cambio en la refracción de ≥ 2 D en esfera o cilindro. Se ha descrito una incidencia variable del 0,04%, del 0,2% o del 0,66%. La miopía alta (> -8.00 D), las córneas delgadas (< 500 µm), el queratocono preexistente, antecedentes alérgicos, traumatismos oculares y frotamiento de ojo se encontraron como factores de riesgo. Se señalaron parámetros e índices de Pentacam, así como la pantalla ABCD para la progresión de la ectasia corneal. La pantalla de progresión ABCD permite la comparación de diferentes tomas a lo largo del tiempo, resaltando cambios en la cara anterior y posterior, paquimetría y agudeza visual con respecto a la población normativa y queratocónica.
dc.description.abstractenglishThe objective of this monograph was to provide the information necessary to understand and identify refractive postsurgical corneal ectasia and its progression using the Pentacam. This monograph was based on bibliographic research in databases in English, Spanish, Portuguese and Russian using thesaurus, boolean operators and truncator as a search strategy. The progression of ectasia was defined as a constant change in at least two parameters such as steepening of the anterior and posterior corneal surface or thinning and/or increase in the rate of change of corneal thickness. Postoperative corneal ectasia is defined as a curve in topography of 5 D or more compared to the postoperative appearance, loss of ≥ 2 Snellen lines of uncorrected visual acuity, and a change in refraction of ≥ 2 D in sphere or cylinder. A variable incidence of 0.04%, 0.2% or 0.66% has been described. High myopia (> -8.00 D), thin corneas (< 500 µm), preexisting keratoconus, allergic history, ocular trauma, and eye rubbing were found as risk factors. Pentacam parameters and indices were noted, as well as the ABCD display for the progression of corneal ectasia. The ABCD progression display allows comparison of different shots over time, highlighting changes in anterior and posterior aspects, pachymetry and visual acuity relative to the normative and keratoconic population.
