Description
Foundation knowledge of optics and refractive errors acquired in 96027 Eye and Visual Systems is expanded in this subject to include detailed learning of the aetiology of refractive errors and the scientific and clinical aspects of their management. Students are encouraged to critically evaluate different methods of ascertaining refractive error and the underpinning ocular biometry based on the current research evidence available. Through a problem-based inquiry approach to learning, students develop an understanding of the advantages and limitations of different methods of correcting ametropia, including optical and surgical methods and how these influence management plans, with particular regard to the life stage, ocular health including strabismus, lifestyle and occupation of the individual. Areas of controversy and complex practice are studied, such as latent and manifest hyperopia, development of astigmatism, the aetiology of myopia, progressive myopia and keratoconus. On completion of this subject students have the orthoptic clinical skills required to objectively and subjectively assess refractive status and be proficient in the prescription of spectacle lenses.
Subject learning objectives (SLOs)
| 31.1. | Apply basic understanding of the different types of refractive errors and the underlying anatomical and optical properties of the eye (ocular biometrics) that cause ametropia to determine the impact of refractive errors on visual performance, patient comfort and functionality. |
|---|---|
| 31.2. | Utilise knowledge of refraction over the life course as well as ocular conditions and disorders that impact and change refractive status and interpret signs and symptoms and plan appropriate methods of investigation and management including optical and surgical therapeutic techniques. |
| 31.3. | Utilise sound clinical reasoning and evidence based practice to effectively manage complex orthoptic and ophthalmic conditions using optical corrections. |
| 31.4. | Use novice practitioner skills for refractive errors investigation such as retinoscopy and subjective refraction and interpret observations and test results to correctly prescribe glasses. |
| 31.5. | Apply advance clinical communication skills to effectively explain test procedures, clinical conditions, therapeutic and surgical management techniques for the correction of refractive errors in terms that can be readily understood by a diverse range of patients, while demonstrating a respectful and compassionate approach to patient care. |

Teaching and learning strategies
Preparation for Learning: Students will be provided with the details of preparation activities each week through the subject’s Canvas site. Activities are designed to help students prepare for their learning in lectures and workshops by engaging them with textbook, journal and other readings, videos, online resources, quizzes and short answer questions and group discussion. In addition, clinical practical classes have pre-practical reading and questions attached, which are expected to be completed prior to attending these classes to ensure maximal time can be spent on hands-on practice.
Active Lectures: Lectures provide an introduction to topic content each week and guest lecturers are invited to share their professional expertise on particular topic areas at relevant times throughout the session. Lectures are active and require students to engage and participate in the analysis of case presentations, quizzes and trivia, class discussion and debate and other active and collaborative learning methods.
Case-based Learning: Case-based learning is a form of problem-based learning (PBL) and a key learning strategy used in workshops. Authentic patient clinical cases are analysed individually and in small (POD) groups. Through this students develop skill in clinical reasoning and practice the application of theoretical knowledge gained in lectures and practical classes to differentially diagnose and develop appropriate plans for the investigation and management of patients with a variety of ocular conditions.
Research-integrated Learning: Taking an evidence-based approach to the investigation and management of patient cases is essential for effective patient care and an important skill for Orthoptic students to develop. Current research is integrated into content provided in lectures and pre-work and students are provided opportunities in workshop classes and through assessment to read, discuss and utilise current research in ophthalmology and orthoptics in the context of evidence-based patient care.
Collaborative Learning: As health professionals, teamwork is an essential skill to ensure patients are managed appropriately within interdisciplinary teams of health professionals. Teamwork skills are developed through collaboration with peers in active lectures and workshops, conducted in collaborative POD classrooms, as well as, when performing clinical skills in practical classes and through group assessment.
Reflective Learning: Students are encouraged to critically reflect on their learning throughout the subject to identify areas where they may improve their performance and to assist in the development of lifelong learning skills. Specific activities where reflective learning is encouraged are; self-evaluation of clinical skill performance in practical classes against OSCE marking criteria and skill achievement checklists and through post lecture/workshop review of learning questions on Canvas.
Practice-based Learning: Clinical practical classes are conducted in small groups (max. 12 students) each week for this subject. These provide students with an opportunity to learn and develop competency in clinical skills relevant to orthoptic practice. These sessions are entirely practice-based and following a short demonstration of the skill, students are closely supervised and provided instruction and feedback, as they participate in hands-on practice of skills, including the use of specialised orthoptic and ophthalmic equipment and technology.
Authentic and Simulated Clinical Experiences: Clinical practical classes are conducted in our dedicated teaching clinic rooms and provide students with access to a simulated clinical environment including, key technology used in professional orthoptic practice. Students participate in role play and simulation of various refractive conditions using lenses.
Self-directed Practice: Clinical practical classes provide students with supervised practice of clinical skills, however, to attain a sufficient level of competency in clinical skills, self-directed practice outside of class time is required. As a general guide, students are expected to spend approximately 1 hour of self-directed practice in the orthoptic dedicated teaching clinics per subject. This is important preparation for clinical placement and your OSCE exams.
Ongoing Feedback: In-class verbal feedback is an important teaching and learning strategy employed throughout the subject. Students are provided with immediate feedback relating to the performance of clinical skills in clinical practical classes and relating to clinical reasoning and understanding of key concepts by staff facilitating workshops. There are opportunities for verbal formative feedback on assignments before submission and detailed written formative and summative feedback following submission. Mock OSCE exams are held to provide students with formative feedback on clinical skills prior to the OSCE exams.
