Supervivencia a largo plazo de las lentes intraoculares de cámara posterior suturadas a esclera

Abstract

asulcus y los factores de riesgo asociados a la rotura de la sutura. A pesar de ser una técnica ampliamente utilizada por los cirujanos de segmento anterior y posterior en aquellos casos donde no hay suficiente soport ecapsular, ésta no está exenta de posibles complicaciones, entre ellas la rotura de la sutura y luxación o subluxación de la lente. OBJETIVO: El propósito de este estudio es el de evaluar a largo plazo la supervivencia y seguridad de la LIO y analizar las posibles causas que conducirían a la rotura de la sutura. METODO: Se ha realizado un estudio retrospectivo de una serie de casos consecutivos. Se han incluido todos aquellos pacientes mayores de 18años y con un período de seguimiento de 10 años. Se ha analizado varios factores: - Preoperatorio: edad, sexo, lateralidad del ojo, longitud axial. - Intraoperatorio: características de la técnica quirúrgica, tipo de lente, tipo sutura, características del colgajo escleral, complicaciones intraoperatorias. - Postoperatorio: complicaciones. - Agudeza visual pre y postoperatoria. - Presión Intraocular pre y postoperatoria. - Función de Supervivencia. RESULTADOS: Se analizaron 345 casos consecutivos de pacientes con sutura escleral de LIO. Veinticinco ojos requirieron una segunda intervención debido ala rotura de una o dos suturas. De estos 25, tres requirieron una tercera intervención. El grupo de adultos jóvenes, uso de una combinación de suturas (Prolene y Mersilene) o la sutura de una solo flap fueron factores de riesgo asociados a la rotura de la sutura tras 10 años de seguimiento. La probabilidad de supervivencia de la sutura tras 10 años se seguimiento fue de 0.79. Tanto la agudeza visual como la presión intraocular se mantuvieron estables tras 10 años de seguimiento. CONCLUSIÓN: La sutura escleral de la LIO en ojos con falta de soporte capsular es una técnica efectiva y segura con un porcentaje bajo de complicaciones y resultados visuales estables a largo plazo.

INTRODUCTION: This study shows the survival function of sclera-sutured intraocular lens (IOL) and the in those cases without capsular support, it is not exempted of possible complications, such as suture breakage and luxation or subluxation of the IOL. PURPOSE: The purpose of this study was to evaluate the long-term stability of scleral-sutured IOL and analyze possible causes of suture breakage. METHODS: This is a retrospective study of consecutive cases. We included all patients that underwent a scleral-sutured IOL with a follow-up longer than 6 months and patients over 18 years of age. Preoperative data (best-corrected visual acuity testing (BCVA), Intraocular pressure (IOP), axial length, and slit-lamp examination), intraoperative data (characteristics of the scleral flaps, suture material and scleral-sutured IOL) and postoperative data (BCVA, IOP, slit-lamp examination and complications) through 10 years were collected for analysis. RESULTS: Three hundred and forty-five consecutive cases of scleral-sutured IOL were included. Twenty-five eyes underwent a second operation after a prior sutured IOL due to suture breakage and three of them needed a third surgery. Younger adults, use a combination of Prolene and Mersilene sutures to perform the surgery and suturing only one flap were found to have higher risk of suture breakage after a follow up of 10 years. The probability of surviving of the scleral-sutured IOL at 10 years after surgery was 0.79. Visual acuity and intraocular pressure were stable all over the years. CONCLUSION:Scleral-sutured posterior chamber IOL in eyes with lack of capsular support is a safe and effective procedure with a low rate of complication and stable visual acuity. Further studies with special focus on younger adults or myopic eyes are required to demonstrate long-term safety in those special cases.
