Integrative teaching is emphasized in both the Academic Department (didactic teaching) and Patient Care Department (clinical instruction) in the new curriculum. The concept is to provide students with a clinical perspective in basic science concepts, thereby developing conceptually based clinical reasoning skills applicable to entry-level practice.

The Academic Department is no longer differentiated into a Basic Science Department and a Clinical Science Department. Hence, courses under this curricular structure are not to be defined as purely basic science courses or clinical science courses. They are assembled and taught in one of the following three manners:

• as conceptually-inclined courses with clinical relevance
• as clinically-inclined courses with conceptual significance
• as a parallel–corresponding courses with equivalent conceptual and clinical relevance

Common denominators among courses in these categories are intended to facilitate the students’ ability to develop clinical reasoning with a conceptual background. Based on this model, emphasis on concept and application varies depending on the course modality.

Presentation of material will be cohesive and synchronized by either integrating or correlating basic and clinical concepts. Conceptually inclined courses and clinically inclined courses require an integrative presentation, whereas parallel-corresponding courses are presented correlatively. Integrative
presentations of conceptually inclined courses involve discussion of clinical associations that are pertinent to the predominant basic science topic taught. In the same manner, clinically inclined courses are taught providing basic science concepts related to the clinical topic
discussed to provide background comprehension.

Parallel-corresponding courses consist of proportioned presentations of health concepts related to primary ocular diseases and ocular diseases secondary to systemic conditions, with their respective clinical applications utilizing a complementary approach. Elective courses also form part of the new curriculum. The purpose of these courses is for optometric student to further enhance their knowledge in specific areas within optometry
in order to encourage the students to apply for optometric residency programs. All these electives are to be offered in the spring term of the third year and all will be evaluated on a pass/no pass basis. The optometric third-year student must enroll in five elective courses.

Residency Program

Primary Eye Care Residency – IAUPR

Mission

The program expects to provide post-graduate training so that the resident can develop proficiency in areas of primary care optometry, gain experience with multidisciplinary settings, and obtain training in pre-and-post -ophthalmic operative care. The program also will provide the resident with experience in teaching and scholarly activities, so that he or she may further pursue a career in education and research.

Program Goals
