 Ophthalmic applications and physiological optics

Ophthalmic developments are also covered by our group through a double research line. First, the development of novel ophthalmic instruments improving capabilities of existing ones concerning characterization/visualization/measurement of ophthalmic-related parameters is addressed. Those ophthalmic instruments can be based on emerging technologies and/or novel applications to the eye of well-know approaches in other research fields. Just as a couple of examples, we have reported on a new ophthalmic instrument (Figure 1) for visualization and characterization of engraved marks in progressive addition lenses (PAL) based on in-line holography (the w-holoscope) and in a novel methodology (Figure 2) to be easily implemented in manual focimeters for improving their capabilities regarding dioptric power measurement and using power vectors formalism (the vectofocimeter).
And second, the group also works in theoretical aspects on physiological and visual optics through the application of advanced mathematical formalisms (power vectors and dioptric power matrices) such as, for instance, astigmatic wavefront propagation, lateral magnification matrix in presence of astigmatism, new subjective routines for refractive error determination, and refractive status prediction from biometric measurements.
