A simple technique for measurement of corneal thickness.

1998

Measurement of corneal thickness has potential benefit both in the fitting of contact lenses and in monitoring any pathology that could affect corneal thickness. Corneal thickness measurement is undertaken using an accessory to the biomicroscope, the optical pachometer, or by means of expensive apparatus such as the ultrasonic pachometer. There are other complex methods, such as laser Doppler interferometry, or ultrasonic rasters of the cornea. In this study, an easier and low cost method, based on the measurement of the optical section formed of the cornea by the biomicroscope illumination system, is proposed. The advantages of this new method are the simplicity of its experimental set-up …

¿Puede hablarse de consenso constructivista en la educación científica?

2021

Artículo colectivo sobre qué entendemos por "constructivismo" en enseñanza de las ciencias. In this paper we analyse some of the criticisms that are being made to the «constructivist paradigm» and their implications on the development of the didactic of the sciences as a theoretical body knowledge.
