Overview
This unit continues development of learning in the optics of spectacle lens corrections, lens forms and designs and the optical and mechanical measurements of spectacles and lenses required in future clinical practice. Ophthalmic optics is a fundamental area of optometry, as the majority of problems dealt with in optometry require optical solutions. Students are introduced to the theory and practice of some essential techniques required to examine patients' eyes and assess visual functions. The aims of this unit are to provide you with an advanced understanding of concepts of ophthalmic optics and some objective techniques for the evaluation of visual function; and to allow you to develop some basic skills in dispensing optics.
Learning Outcomes
On successful completion of this unit you will be able to:
- Solve problems related to the optics of spectacle lenses arising in clinical practice
- Solve problems relating to the optics of lenses that may arise in clinical practice.
- Demonstrate practical skills associated with dispensing optics
- Describe the principles of and demonstrate practical skills of some individual techniques required to examine patients' eyes and assess visual functions.
Content
This unit addresses a range of optical factors related to spectacle lenses: neutralisation and transposition of spectacle lenses; the combination of obliquely crossed cylinders; spectacle lens problems: off-axis aberrations, factors affecting spatial perception, cosmesis, weight, reflection, anisometropia, near vision problems, and prescription problems.
You will also be introduced to the principles and fitting of progressive addition lenses, the optics of low vision aids, intraocular lenses and refractive surgery.
You will learn to perform adjustment of spectacle frames, lens marking, and lens verification (measurements of lens powers). They will also learn the practical skills and theory underpinning some objective methods of evaluating visual function: ophthalmoscopy and retinoscopy.
Learning in this unit further contributes to the development of graduate skills relevant to the Optometry entry-level competency standard elements prescribes spectacles and dispenses spectacle prescriptions accurately and the performance criteria within these elements.
Learning Approaches
This unit involves lectures, tutorials and practical work. Learning is also supported by an online website which provides a range of study materials and activities.
Feedback on Learning and Assessment
Formative assessment will include feedback on the development of your clinical and communication skills in clinical procedures through the practical sessions, and through discussion of examples of problem solving for clinical case based problems during lectures and case reports.
Assessment
Overview
The assessment is comprised of three main tasks.
The first task is skills slide examination to examine knowledge and understanding of concepts.
The second task is a practical examination to assess dispensing laboratory skills.
The third task is a written examination after the end of semester to examine knowledge, understanding of concepts, and calculation skills
.
Satisfactory performance in the third task is a requirement for passing the unit. At least 50% must be obtained at it for a passing grade to be awarded. The Faculty of Health Threshold Assessment Policy will apply where student performance in an assessment item is unsatisfactory.
Unit Grading Scheme
7- point scale
Assessment Tasks
Assessment: Skills slide assessment
This will include a range of questions assessing knowledge of optics relating to spectacle lenses, the ability to solve problems relating to the optics of lenses, and the use of retinoscopy and ophthalmoscopy.
Assessment: Optical dispensing
This will include assessment of practical skills in optical dispensing including lens verification and lens layout.
Assessment: Examination
This will include a range of questions which will assess knowledge of spectacle lens optics and theory of clinical techniques, and the ability to solve problems relating to the optics of lenses.
.
Threshold Assessment:
Must be passed
Academic Integrity
Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.
Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.
You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.
Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.
