Resumen
La Extracción Lenticular por Pequeña Incisión (SMILE) y la Keratomileusis Subepitelial por Láser (LASEK) son seguras para la miopía. LASEK reduce el astigmatismo, mientras que SMILE induce menos coma horizontal seis años después de la cirugía.
Área de la Ciencia:
- Oftalmología Oftalmología.
- Cirugía refractiva La cirugía refractiva es una cirugía refractiva.
- Fisiología corneal Fisiología corneal
Sus antecedentes:
- La miopía de leve a moderada requiere una corrección refractiva efectiva.
- La extracción lenticular por pequeña incisión (SMILE) y la ceratomileusis subepitelial láser (LASEK) son opciones quirúrgicas populares.
- Los datos comparativos a largo plazo sobre los cambios en la córnea y la calidad visual después de estos procedimientos son valiosos.
Objetivo del estudio:
- Para comparar el componente esférico de la córnea, el astigmatismo regular, el astigmatismo irregular y la calidad visual seis años después de SMILE frente a LASEK para la miopía leve a moderada.
Principales métodos:
- Estudio comparativo retrospectivo de 35 ojos (SMILE) y 36 ojos (LASEK).
- La topografía corneal (OCT de fuente barrida) y las aberraciones del frente de onda se evaluaron antes de la operación y 6 años después de la operación.
- Se realizó el análisis de Fourier de los parámetros queratométricos y el análisis de correlación lineal.
Principales resultados:
- Tanto SMILE como LASEK mostraron índices de seguridad y eficacia comparables a los 6 años.
- LASEK condujo a un aplanamiento significativo de la córnea anterior y redujo el astigmatismo regular.
- SMILE indujo significativamente menos coma horizontal en comparación con LASEK.
Conclusiones:
- SMILE y LASEK son seguros y efectivos para la miopía de leve a moderada.
- LASEK ofrece ventajas en el aplanamiento de la córnea anterior y la reducción del astigmatismo regular.
- SMILE demuestra su superioridad para minimizar el coma horizontal inducido.

01:26Areas Within Irregular Boundaries
386
Calculating areas within irregular boundaries, such as along rivers or curved roads, is crucial in various fields, including surveying, engineering, and environmental management. Surveyors often begin by creating a traverse, a connected series of straight lines approximating the area's boundary. The coordinates of each traverse point are essential for calculating the enclosed area. The double meridian distance formula is a widely used technique for this purpose. This method utilizes the...

01:05Quality Control
2.9K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

01:19Quality Assurance
2.5K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

01:19Quality of Water
576
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.
