Resumen
Consideramos importante corregir miopía moderada en niños menores de 10 años, implementando el uso de lentes asféricas porque es imprescindible que obtengan excelente visión y lograr buen desarrollo en todo ámbito tanto educativo, personal y social. La metodología fue en base a la evaluación de los diferentes casos de ametropías, para enfocarnos en aquellos niños que tienen miopía moderada, realizando refracción subjetiva con optotipos de figuras y cartilla de Snell, y refracción objetiva, (retinoscopía) con ciclopegía en tres secciones para análisis y obtención de resultados (prescripción de recetas (RX). En el estudio se analizó un promedio de 110 niños de los cuales el 55% fueron niñas y el 45% niños entre 6 a 10 años de edad. De Enero a Marzo del 2010, se observó que el 35% mostró A/V SC 20/40 en el O.D. y un 29% A/V SC en el O.I.; un 20% tiene una A/V SC de 20/100 en O.D frente a un 15% que presenta A/V SC 20/60 en el O.I lo que implica un promedio de ametropia considerable a diagnosticar de miopia moderada. Transcurrido los tres meses de observación se procedió a la aplicación de lentes asféricas obteniendo como resultado final que el 80% se evalua con A/V SC de 20/20 O.I frente a un 20% de 20/25 O.; sin embargo el 95% presenta una evaluación de 20/20 y el 5% de 20/25 respectivamente Concluimos que los niños seleccionados al utilizar este tipo de lentes asférica por su asfericidad son livianos, estéticos generalmente recibiendo visión central nítida coincidiendo paralelamente al eje visual como resultado optima visión.

From January to March 2010 , it was observed that 35% showed A / V SC 20/40 in the RE and 29% A / V SC in the OI, 20% had an A / V SC of 20/100 in OD compared to 15% that presents A / V SC 20/60 in the OI which implies a considerable average of ametropia to diagnose moderate myopia After the three months of observation we proceeded to the application of aspheric lenses obtaining as a final result that 80% is evaluated with A / V SC of 20/20 OI versus 20% of 20/25 O; s However, 95% presents an evaluation of 20/20 and 5% of 20/25 respectively. We conclude that the children selected when using this type of aspherical lens for their asphericity are light, aesthetic, generally receiving clear central vision coinciding parallel to the visual axis as a result, optimal vision.
