Title: Corneal Transplantation - where are we now?
Cornea is the foremost transparent tissue of the globe. It serves as protection to the internal structures of the globe, and it has the highest refractive power in the eye. Various corneal diseases can lead to cloudiness and opacities of the cornea, thereby affecting vision. Although prompt diagnosis and treatment may reverse the conditions, at times the corneal opacities may become irreversible and permanent. The primary purpose of corneal transplantation is to improve vision through the replacement of the diseased cornea with a clear high quality graft. Traditionally, full thickness penetrating keratoplasty (PK) remained the only procedure in replacing the cornea. However, the introduction of lamellar keratoplasty (LK) in replacing selective layer of the cornea has gained popularity among corneal surgeons. Endothelial keratoplasties (EK) are performed in corneas with endothelial cell diseases, while anterior lamellar keratoplasties (ALK) are done in corneas with pathologies which do not involve the endothelial layer. Recent advances in femtosecond lasers have provided new strategies in corneal tissue preparation and corneal wound designs. Finally, sterile corneas and keratoprosthesis are used in complex corneal diseases in order to salvage vision.

Title: Contact Lens Myopia Control
An increase in the prevalence of myopia has heightened the awareness of myopia and its effects on ocular health and daily activities. This lecture will provide some insight into soft bifocal and orthokeratology myopia control, including tips for optimizing myopia control, talking to parents, and determining the modality that may be best for an individual patient. Evidence regarding kids’ abilities to wear contact lenses will be presented, as well as subjective and objective information about kids’ vision while wearing soft bifocal contact lenses. At the end of this lecture, eye care practitioners will be able to confidently offer contact lenses as a method of myopia control for young children.

Title: Infra-red, Interferometry and OCT – new imaging and analysis of the anterior segment
Clinicians have been presented with a plethora of new technologies for imaging and analysing the body and nowhere more so than the eye. The use of infra-red digital imaging coupled to a slit lamp or other dedicated camera has meant the meibomian glands can be viewed in vivo. The advent of video interferometry has meant that the structure and behaviour of the tear film and specifically the lipid layer can be analysed dynamically.
Simultaneously with the emergence of OCT as a method for examining the posterior segment the possibilities for anterior segment imaging and measurement began to be appreciated. All manufacturers rapidly developed methods of adapting their instruments to anterior segment imaging ranging from simple forehead spacers to extra lens systems.
Many areas of the anterior segment lend themselves to OCT analysis such as; tear prism measurement, pachymetry, assessment of the angle and anterior chamber depth, topographical representation, imaging the patency of iridotomies and even viewing the lens and anterior vitreous. Contact lens research has also been greatly enhanced by the use of OCT coinciding with the re-emergence of scleral and semi-scleral lens fitting.
This presentation will explain the development of new imaging techniques and describe their use through images and cases seen in practice.

Title: How to Mix Oil and Water – The Meibomian Gland in Sickness and Health
Dry eye is one of the most common ocular complaints suffered by people throughout the world and it is particularly prevalent in Asian countries. Current opinion, views the loss of normal function in the meibomian glands as the major contributory factor in this potentially debilitating disease. While this premise is apparently straightforward, it has become clear that translating it into effective clinical management strategies requires a deeper grasp of the actions of these glands, as well as the oily secretions they produce. This awareness is prompting a re-evaluation of the functional behavior of the tear film and the role of meibum, as well as focusing research efforts into meibomian gland activity. The task in this presentation is to give an overview of this landscape as a background to our own work which has attempted to provide clarity in three main areas, first by establishing the natural history of the meibomian gland, second by looking at how its structure and function interact with the subjective symptoms reported by dry eye sufferers and third by gauging the effect of external influences, such as contact lens wear.

Title: Offering your patient a wonderful journey
Patient’s journey is an important aspect to patient experience. It is one of the key factors that drives the loyalty of a patient to a health care provider. In order to optimize a patient’s journey, it is important to manage carefully on every single point of interaction between the practice and the patient. This presentation will give an overview of the patient’s journey regarding the contact lens service in an optometric practice. The issues that may help optimize the patient’s journey will be discussed. These include ways to elicit patient’s symptoms, tools for presenting clinical results to the patient, identifying and meeting the patient’s needs and proper training to supporting staff.
