Sample subject outline - Semester 2 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

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.

Aims

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.

Objectives

On completion of this unit you will be able to:

1. to recognise and solve problems related to the optics of spectacle lenses arising in clinical practice
2. demonstrate practical skills associated with dispensing optics
3. describe the principles of and demonstrate practical skillls of some individual techniques required to examine patients' eyes and assess visual functions.

Graduate capabilities addressed in this unit include:
- knowledge and skills pertinent to the practice of optometry
- critical, creative and analytical thinking, and effective problem-solving

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 refractice surgery.

You will lean to perform adjustment of spectacle frames, lens marking, glazing and frame repairs. You will also learn the practical skills and theory underpinning some objective methods of evaluating visual function: keratometry, optometers, ophthalmoscopy and retinoscopy.

Approaches to Teaching and Learning

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.

Assessment

This unit has 4 pieces of summative assessment. Students must satisfactorily complete each type of assessment.
