Below is a list of various names and their definitions:
- Optical axis? A line that most closely connects the three Purkinje images
- Visual axis? A line from the target through the nodal point to the fovea
- Line of sight? A line from the target through the centre of the pupil to the fovea
- Pupillary axis? A line perpendicular to the cornea that passes through the pupil centre
- Fixation axis? A line from the object which arrives at the fovea.

Objective: To report the outcomes of IntraLase® FS 150 kHz (AMO) and VISX S4 IR® wavefront-guided Lasik done on patients from May 2011–February 2012.
Design and method: A prospective study of 155 i-Lasik eyes done by the same surgeon in private practice. Inclusion criteria were: no previous ocular surgery, no ocular pathology and an aim of emmetropia. Eighty-seven eyes were available for the 4-year post-operative evaluations (56%). Pre-operative demographics, intra-operative incidents and post-operative results are presented at 3-month and 4-year intervals.
Results: Findings on safety, efficacy, average flap thickness, refractive outcome predictability and stability, enhancement rate, higher order aberrations (HOA) and K-max values will be discussed.
Conclusion: Evaluation of i-Lasik™ clinical results show impressive safety, efficacy and long-term stability.

Cranial nerve III (oculomotor) pathology is a relatively common presenting complaint in general ophthalmology practice. Lesions can be broadly classified into ischaemic or intracranial causes, with the latter mandating urgent neuro-imaging to exclude a potentially life-threatening aneurysm. By combining a relevant clinical history together with a structured anatomical approach to the general, neurological and ophthalmological examination, the clinician is able to localise a likely level and thus guide optimal investigation and management. Classifying the lesion according to various patterns of involvement focuses the differential as well as highlights potential warning signs. We propose adopting a system of classification that differentiates between single nerve involvement (isolated) versus multiple cranial nerve, peripheral nerve and cerebellar involvement (complex). The presence of pupillary involvement assumesparamount importance in this classification system as the presence thereof is almost pathognomonic of intracranial pathology, while pupil-sparing pathology is conversely almost always ischaemic in origin. The deficit at the orbit itself may be divided into a single muscle involvement (partial) or diplopia with an abducted, hypotropic eye plus ptosis of the associated lid (complete).

This book was recommended to me by our long-lost colleague Lewis Levitz who left South Africa in 2007 and is now practicing ophthalmology in Melbourne. South Africa’s loss, Australia’s gain. In Chapter 4 of this book, the author says that the journey of the first humans to Australia is one of the most important events in human history. Well, I’m sure that this journey was also one of the most important events in the Levitz family history!

It was a midlife crisis thing. It was either going to be a shiny, fast, flat red car, or a challenge. I decided the 2016 Absa Cape Epic was a safer and probably less expensive way to ‘break free from these fetters, or lose myself in dotage’, as Mark Antony said. And so, in autumn of 2015, I sat at the computer, filled in an extensive entry form, and hit ‘send’. I asked an old friend, Anton, to be my partner, and the preparation began.
