ABSTRACT
Propósito Existe una constante controversia entre la realización de la cirugía de la catarata de un ojo o de ambos ojos en la misma sesión quirúrgica. El objetivo de este estudio es revisar la evidencia científica sobre eficacia y seguridad, valorar la reducción de costes de la cirugía de catarata bilateral simultánea en el mismo día en comparación con la cirugía de la catarata secuencial en 2tiempos, así como comparar la tasa de complicaciones asociadas. Métodos Se ha hecho una búsqueda exhaustiva en las bases de datos PubMed y Web of Science para identificar artículos relevantes sobre cirugía de catarata bilateral secuencial desde el año 2000 hasta el 31 de diciembre de 2020. Resultados La literatura revisada muestra evidencias sólidas que demuestran la eficacia y seguridad de la cirugía de la catarata bilateral simultánea cuando se han seguido protocolos muy estrictos de esterilidad entre la cirugía de cada ojo. Bajo estas condiciones, en los estudios no se ha encontrado una mayor tasa de complicaciones postoperatorias que en la cirugía de catarata secuencial en 2tiempos. Conclusiones Existe evidencia sustancial de que la cirugía de catarata bilateral simultánea es una adecuada opción quirúrgica para la resolución de la catarata, que provoca una rápida rehabilitación visual y sin mayor número de complicaciones que la cirugía secuencial en 2tiempos cuando se extreman los protocolos de esterilidad entre los procedimientos de ambos ojos. Además, proporciona una reducción en el gasto sanitario. Existe un miedo psicológico a la realización de la cirugía bilateral por el potencial riesgo de complicaciones que afectaría a los 2ojos operados. Dentro del presente artículo discutimos la eficacia, seguridad, tasa de complicaciones y costes asociados en la cirugía de catarata bilateral simultánea en el mismo acto quirúrgico (AU)
Purpose There is a constant controversy between performing cataract surgery for one eye or for both eyes in the same surgical session. The objective of this study is to review the scientific evidence on the efficacy and safety, determine the reduction of costs of sequential bilateral cataract surgery on the same day compared to unilateral cataract surgery, as well as to compare the rate of associated complications. Methods A comprehensive search of the PubMed and Web of Science databases has been conducted to identify relevant articles on sequential bilateral cataract surgery from 2000 to 31 of December of 2020. Results Literature shows that there is strong evidence demonstrating the efficacy and safety of same-day sequential bilateral cataract surgery. Studies have not found a higher rate of postoperative complications compared to unilateral cataract surgery. Conclusions Same-day sequential bilateral cataract surgery is a good surgical option for the resolution of the cataract, provides rapid visual rehabilitation and without greater risks than unilateral surgery. It also provides a reduction in sanitary costs. There is a psychological fear of performing bilateral surgery due to the potential risk of complications that would affect both operated eyes. In this article we discuss the efficacy, safety, complications rate and associated costs in sequential bilateral cataract surgery in the same surgical act (AU)

BACKGROUND AND THE PURPOSE OF THE STUDY: Melatonin has recently been found in several plant tissues. Some reports show that the majority of the herbs containing the high level of melatonin have been used traditionally to treat neurological disorders or diseases associated with the generation of free radicals. Current study was undertaken to screen some medicinal plant species with historical evidence of efficacy in the treatment of neurological and antioxidant deficiency related disorders for their melatonin content. The melatonin content of boiled and alcoholic extracts were also compared. METHODS: In this study, three medicinal herbs, Tanacetum parthenium (L.) Schultz. Bip. (Asteraceae), Tripleurospermum disciforme (C.A.Mey) Schultz. Bip. (Asteraceae) and Viola odorata (L.) (Violaceae) were analyzed using high performance liquid chromatography with ultraviolet detector (HPLC-UV), enzyme linked immunosorbent assay (ELISA) and thin layer chromatography (TLC). RESULTS: Melatonin content in the dry plant powders differed with different assay methods (p < 0.001). For example, the melatonin content in T. disciforme was determined as 3.073 µg/g and 2.906 µg/g by the HPLC and the ELISA methods, respectively. MAJOR CONCLUSION: The results demonstrated that a hydroalcoholic solution could extract more melatonin from flowers of the herbs than hot water (p < 0.001). The presence of melatonin in these plant tissues may provide some explanation for the anecdotal evidence of their physiological effects in humans.
