Resultados postquirúrgicos en la cirugía combinada de glaucoma: Comparación del implante express con la trabeculectomía estándar
2009
espanolObjetivos: Evaluar los hallazgos postquirurgicos y el exito tras cirugia combinada mediante facoemulsificacion e implante Ex-PRESS comparado con cirugia combinada con trabeculectomia estandar. Metodos: En esta serie prospectiva de 40 ojos consecutivos comparamos 20 ojos de 17 pacientes tratados mediante facoemulsificacion combinada con cirugia filtrante de glaucoma con implante de valvula Ex-PRESS bajo un colgajo escleral con 20 ojos controles en 20 enfermos que fueron sometidos a facoemulsificacion combinada con trabeculectomia estandar. Resultados: El tiempo de seguimiento medio fue de 9,7 meses (rango: 4,5-15) en el grupo Ex-PRESS y 10,3 meses (rango 3,5-14,5) en el grupo trabeculectomia. La PIO media fue significativamente superior en el postoperatorio precoz en el grupo Ex-PRESS comparada con el de trabeculectomia. La tasa de complicaciones en dicho periodo resulto superior en el grupo sometido a trabeculectomia. No se objetivaron diferencias significativas en la tasa de exito entre ambos grupos mas alla de la primera semana. Conclusiones: El implante Ex-PRESS constituye una alternativa eficaz y segura a la trabeculectomia en casos seleccionados que permite disminuir notablemente las clasicas complicaciones postquirurgicas precoces asociadas a la trabeculectomia. EnglishPurpose: To evaluate postoperative outcomes and success after combined phacoemulsification and glaucoma surgery with Ex-PRESS miniature implant compared with combined surgery with standard trabeculectomy. Methods: In this prospective series of 40 consecutive eyes we compared 20 eyes in 17 patients treated with combined phacoemulsification and glaucoma filtering surgery with the Ex-PRESS miniature glaucoma implant under a scleral flap with 20 matched control eyes in 20 patients who underwent combined cataract and glaucoma surgery with trabeculectomy. Results: The average follow-up was 9.7 months (range 4.5 to 15) for the Ex-PRESS group and 10.3 months (range 3.5 to 14.5) for the trabeculectomy group. The mean IOP was significantly higher in the early postoperative period in the Ex-PRESS group compared with the trabeculectomy group. Complications rate in the early postoperative period was significantily higher in the trabeculectomy group. No significant differences were objectified in success between both groups after the first week. Discussion: The Ex-PRESS implant is an effective and safe alternative to standard trabeculectomy in selected cases which makes possible to reduce remarkably the classic early postoperative complications associated with trabeculectomy.
