It is designed to promote both the management and understanding of them, allowing the confidence of a good optometric diagnosis, which in turn should be linked to the areas of medical care if necessary. Each of them was investigated its objective, parts, operation and the procedure to be followed for its correct use. It consists of a compilation of the equipment and instruments studied during the current semester: In Unit 1 "Integral Optometry" the lensometer, the test box, the occluder, the test frame, the flashlight, the pupilometer, the biomicroscope or the slit lamp, the direct ophthalmoscope, the indirect ophthalmoscope, the retinoscope, optotypes, the aurefractometer, the phoropter, the stereopsis tests, the Amsler grid, the color vision test.

In Unit 2 "Orthoptics or visual therapy and low vision" the prism cover test, the flippers, the Krimsky rule, the Bagolini test, telescope, magnifying glasses, the green cane, optotypes for low vision.

In Unit 3 "Contactology and prosthetics" placid discs. In Unit 4 "Specialized examinations" the perimeter, the corneal topographer, the pachymetry and the pentacam. This research is feasible, since there is adequate time to obtain the information. In addition, the resources for its execution are available, since through surveys and the Internet it will provide all the facilities to collect the information and data required.

Cuando se coloca de un lente positivo, los rayos luminosos, luego de atravesado, se hacen convergentes y no inciden en forma de paralela al telescopio. Mecanismo de marcaje: Posee tres puntos de marcaje alineados. Fuente: tomada de www. Sostenga un papel blanco contra el objetivo. Se procede a enfocar el instrumento al sistema visual del examinador mediante el ocular.

Si el valor resultante no es cero tenga en cuenta el valor encontrado para compensarlo al poder encontrado al final del ejercicio. Gire el tambor de poder hacia el lado de los positivos y comience a disminuir lentamente el poder con la mano derecha. Gire el tambor de grados hasta que esto sea cierto y anote el poder resultante como la esfera. La diferencia o recorrido entre un valor y otro es valor del cilindro.

El eje del cilindro es el indicado en el tambor de grados. Colocar la gafa o lente con la superficie ocular mirando hacia abajo. Figura 3: Caja de pruebas probines. Tomada de: Forini, P. Figura 4: lentes de caja de pruebas que van en paso de 0,25 aproximadamente. Potencia variable desde 0,25D hasta 20,00D aproximadamente.

Potencias desde 6,00D en pasos de 0,25D. La caja de lentes se usa colocando los lentes en la montura de prueba hasta obtener el lente adecuado para corregir el error refractivo del paciente. Tomada de: Baplas. Varilla adaptable en longitud. Aro fijo con escala en grados. Soporte dijo posterior, con capacidad para una lente. Regla milimetrada para indicar la distancia nasopupilar.

Phase pupil filters for improvement of the axial resolution in confocal scanning microscopy 1 edition published in in English and held by 1 WorldCat member library worldwide. The SPC is proven a simple yet efficient model for extracting the lateral resolution as a high-level property of complex plenoptic capturing systems. Tunable axial resolution in confocal scanning kptometricos by controlled symmetrical defocusing 1 edition published in in English and held by 1 WorldCat member library worldwide. A digital method has been developed insttumentos increase the depth of field of Integral Imaging systems in the reconstruction stage. This agreement strengthens the conclusion that the SPC fills the gap between ray-based models and the real system performance, by including the focal information of the system as a model otpometricos. This operator utilizes focal properties of the capturing system as well as the geometrical distribution of the light containers which are the elements in the SPC model.
