FURTHER INFORMATION

Learning outcomes of the course:

 

At the end of the course, students should be able to:

- Understand the physical nature of light, the optical singularities of the different structures of the human eye and their contribution to the final quality of the retinal image.

- Understand the physical principles of modern wavefront aberrometers like the Shack-Hartmann wavefront aberrometer and use them to obtain a comprehensive description of the optical aberrations of the eye.

- Develop optical models of the human eye and use them as a tool to study the optical performance of devices such as ophthalmic, contact or intraocular lenses.

- Apply optical modeling techniques to predict the average optical / image quality performance of a population or an individual.

- Use computational tools, such as Zemax and Matlab optical design software, to infer visual function from structure, based on the topographical and morphological characteristics of the different elements of the eye.

- Use and understand the classical methods used in physical optics to classify image quality of an optical system, such as modulation and phase transfer functions, point spread function, optical path differences, Strehl ratio and others.

 

The acquired knowledge will serve as basis for understanding the fundamental principles of visual optics and optical design of complex ophthalmic elements, such as multifocal contact lenses and diffractive intraocular lenses to correct presbyopia.
