dc.description.abstractObjetivos: En este estudio se pretendió identificar los factores asociados a pérdida de células endoteliales durante la extracción extracapsular de catarata por facoemulsificación. Materiales y métodos: Se realizó un estudio observacional, longitudinal, retrospectivo de las historias clínicas de pacientes sometidos a cirugía de catarata por facoemulsificación microincisional coaxial por un único cirujano (VGR) durante los meses de Enero 2016 a Junio 2016. Resultados: Se encontró una pérdida endotelial promedio de 6.4 +/- 10%. Como factores asociados a pérdida de células endoteliales se encontraron la clasificación más avanzada de la catarata (LOCS III), el tiempo total de ultrasonido y la energía acumulada disipada (CDE por su nombre en inglés cumulative dissipated energy). Conclusión: Es preferible realizar la facoemulsificación cuando la catarata no haya alcanzado los grados más avanzados (más allá de NC2 en la clasificación LOCS III), sobretodo en pacientes con endotelios alterados que por ende tienen mayor riesgo de descompensación corneal. Adicionalmente es preferible realizar técnicas quirúrgicas para la fragmentación del núcleo en las cuales se emplee menos CDE y tiempo total de ultrasonido.spa

dc.description.abstractenglishObjectives: This study aimed to identify the factors associated with endothelial cell loss during extracapsular extraction of cataract by phacoemulsification. Materials and methods: An observational, longitudinal, retrospective study was carried out of the medical records of patients undergoing cataract surgery by coaxial microincisional phacoemulsification by a single surgeon (VGR) during the months of January 2016 to June 2016. Results: An average endothelial loss of 6.4 +/- 10% was found. Factors associated with endothelial cell loss were the most advanced cataract classification (LOCS III), total ultrasound time, and cumulative dissipated energy (CDE). Conclusion: It is preferable to perform phacoemulsification when the cataract has not reached the most advanced degrees (beyond NC2 in the LOCS III classification), especially in patients with altered endotheliums who therefore have a higher risk of corneal decompensation. Additionally, it is preferable to perform surgical techniques for the fragmentation of the nucleus in which less CDE and total ultrasound time are used.eng
