Retrospective study of secondary implantation of retroiridial fixation lenses in patients without capsular support: functional results and complications.

INTRODUCTION: The correction of aphakia when there is no adequate capsular support remains a therapeutic challenge. The use of retroiridial fixation lenses has been extended given their lower complication rate compared to other available options. MATERIAL AND METHODS: Retrospective study including all cases operated with an Artisan® retropupillary aphakia implant. RESULTS: 33 eyes were included out of a total of 28 patients. The follow-up period has been 38.55 months (1-96). 32.3% had a lens dislocation and 67.7% had an intraocular lens dislocation. The previous mean best corrected visual acuity (BCVA) was 1.18 ± 0.79 logMAR and post-intervention 0.36 ± 0.62 (p < 0.01). 93.8% of the patients presented a final BCVA equal to or better and 62.5% an improvement of 3 or more lines. The most frequent complication was corectopia (31.3%) and hypotony in the immediate postoperative period (21.9%). An epiretinal membrane (ERM) developed in 18.8% and cystic macular oedema (CME) in 9.4%. The presence of complications in the postoperative period did not statistically influence the final BCVA. CONCLUSIONS: The retropupillary Artisan® lens allows the correction of aphakia with satisfactory visual results and a low rate of complications.

Estudio retrospectivo de implante secundario de lentes de fijación retroiridiana en pacientes sin soporte capsular: resultados funcionales y complicaciones / Retrospective study of secondary implantation of retroiridial fixation lenses in patients without capsular support: functional results and complications

Introducción La corrección de la afaquia en ausencia de un soporte capsular adecuado sigue suponiendo un reto terapéutico. Se ha extendido el uso de las lentes de fijación retroiridiana dada su menor tasa de complicaciones con respecto a otras opciones disponibles. Material y métodos Se realizó un estudio restrospectivo incluyendo todos los casos intervenidos con un implante Artisan® Afaquia retropupilar en un centro de tercer nivel. Resultados Se incluyeron 33 ojos de un total de 28 pacientes. El periodo de seguimiento ha sido de 38,55 meses (1-96). Un 32,3% tenían una luxación del cristalino y un 67,7% de la lente intraocular. La mejor agudeza visual corregida (MAVC) media previa fue 1,18 ± 0,79 logMAR y post intervención de 0,36 ± 0,62 (p < 0,01). El 93,8% de los pacientes presentó una MAVC final igual o mejor a la previa y el 62,5% una mejoría de 3 o más líneas. La complicación más frecuente fue la corectopia (31,3%) y la hipotonía transitoria en el postoperatorio inmediato (21,9%). En un 18,8% se desarrolló una membrana epirretiniana (MER) y en un 9,4% edema macular (EM). La presencia de complicaciones en el postoperatorio no influyó de forma estadísticamente significativa la MAVC final. Conclusiones La lente Artisan® retropupilar permite corregir la afaquia con resultados visuales satisfactorios y con una reducida tasa de complicaciones (AU)
