RESUMENObjetivo: Evaluar los resultados de un programa de cirugía mayor ambulatoria en pacientes intervenidos quirúrgicamente de diversas patologías oculares en nuestro hospital. Métodos: Este estudio retrospectivo incluye 13.878 pacientes intervenidos de forma programada por el Servicio de Oftalmología desde septiembre de 1998 a diciembre de 2004. En 11.187 pacientes se realizaron diferentes procedimientos quirúrgicos de forma ambulatoria, siendo la cirugía de catarata (facoemulsificación) la operación mayoritaria (8.155 casos). Se han analizado diversos índices (sustitución, suspensión, ingresos, reingresos), así como el rendimiento quirúrgico y las complicaciones sisté-micas y oculares que surgieron dentro de las primeras 72 horas tras la cirugía. La medición de las variables se realizó mediante frecuencias relativas. El análisis utilizado para la evolución de las complicaciones en el período de estudio fue la Chi cuadrado de tendencias. Resultados: 13.878 pacientes fueron intervenidos en el período indicado, de los que 11.187 se operaron de forma ambulatoria (índice de sustitución global del 80,6%). El rendimiento quirúrgico medio fue 74,36%. El índice de ingresos tras la cirugía fue ARTÍCULO ORIGINAL ABSTRACT Purpose: To evaluate the outcomes in our hospital of an ambulatory major surgery program in patients with a variety of different ocular pathologies. Method: This retrospective study includes 13,878 patients who underwent programmed surgery by the Department of Ophthalmology between September 1998 and December 2004. Different ophthalmological surgical procedures were performed as outpatient surgery in 11,187 patients, with cataract surgery (phacoemulsification) being the most frequent operation performed (8,155 cases). We have analysed several indicators (substitution, suspension, admission and readmission rates), as well as surgical yield and systemic and ocular complications which appeared within 72 hours after surgery. The variables were measured as relative frequencies. The evolution of complications during the study period was analysed by the Chi-square trend test. Results: 13,878 patients had ophthalmic surgery during the study period; 11,187 had outpatient surgery with a global substitution ratio of 80.6%. The median surgical yield was 74.36%. The admission rate after surgery was 4.46% (499 patients), with 92.18% (460) of these requiring immediate admission. Twenty-one patients suffered from severe
