At the end of the course the student must be able to:
1) know the orthokeratological mechanism and the biochemical, biophysical and physiological responses to corneal molding with inverse geometry contact lenses.
2) Describe the biomicroscopic, topographic, biochemical and immunological changes that occur in the cornea as a consequence of the interaction with the mechanical forces exerted by contact lenses.
3) Know the main mechanisms, the fitting process and the ocular repercussions of orthokeratology.
4) Select the candidate for this type of treatment, trial lenses, and carry out the pertinent modifications, as well as the subsequent control of the patient.

1. Basic and general
CB6 Possess and understand knowledge that provides a basis or opportunity to be original in the development and / or application of ideas, often in a research context.
CB7 That students know how to apply the knowledge acquired and their ability to solve problems in new or unfamiliar environments within broader (or multidisciplinary) contexts related to their area of study;
CB8 That students are able to integrate knowledge and face the complexity of formulating judgments based on information that, being incomplete or limited, includes reflections on social and ethical responsibilities linked to the application of their knowledge and judgments;
CB9 That students know how to communicate their conclusions and the knowledge and ultimate reasons that support them to specialized and non-specialized audiences in a clear and unambiguous way;
CB10 That students possess the learning skills that allow them to continue studying in a way that will be largely self-directed or autonomous
CG1 Know, understand and apply the principles, methodologies and new technologies of optometry, as well as the acquisition of the skills and competencies described in the general objectives of the degree.
CG2 Demonstrate the ability to work in collaboration with other professionals as a member of a multidisciplinary team with a high degree of efficiency.
CG5 Transmit the results of the research to specialized, academic and general public.
2. Transversal
CT1 Participate in debates and discussions, direct and coordinate them and be able to summarize them and extract from them the most relevant conclusions and accepted by the majority.
CT2 Use the different techniques of oral and written presentation, presentations, panels, etc., to communicate their knowledge, proposals and positions.
CT3 Develop critical and self-critical and decision-making capacity.
CT4.- Ability to manage Information and Communication Technologies (ICT)
CT5.- Ability to reflect from different perspectives of knowledge.
3. Specific
CE1 Acquire specific criteria for clinical performance to specialize the student in the different clinical fields of visual care: pediatric optometry, geriatric optometry, visual therapies, low vision, ocular surface and contact lenses.
CE4 Deepen the study of the basic sciences of vision, as a tool for knowledge and support for professional and research specialization.
CE5 Know, understand and apply screening concepts in visual and ocular primary care.
CE6 Apply the methodology and procedures of scientific research in Vision Sciences.
CE7 Acquire knowledge and skills from different perspectives of knowledge in Vision Sciences.
Each unit will be taught by the teacher through the lecture technique. At its end, a time of directed discussion will be allocated, with the potential participation of the entire class, for each of the topics addressed. Use of special techniques that facilitate the understanding and fixation of the contents, as well as the promotion of attitudes and skills that allow improving the optometrist-patient relationship.
The resulting grade will be the result of: 1) Theoretical final exam corresponding to the knowledge and skills acquired during the practices, which represents 60%; 2) Attendance at face-to-face classes, evaluation of practices and resolution of clinical cases, which represents the remaining 40%.
The fraudulent performance of any exercise or test required in the evaluation of a subject will imply the qualification of failure in the corresponding call, regardless of the disciplinary process that may be followed against the offending student. It is considered fraudulent, among others, the performance of plagiarized work or work obtained from sources accessible to the public without reworking or reinterpretation and without citation of the authors and sources.
Autonomous individual or group study 15 h
Recommended readings, activities in the library or similar 10 h
Preparation of oral presentations, debates or similar 1 h
