Virtual simulators have been widely implemented in medical and surgical training, including ophthalmology. The increasing number of published articles in this field mandates a review of the available results to assess current technology and explore future opportunities. ⋯ Virtual reality simulators are an effective tool in measuring performance and differentiating trainee skill level. Additionally, they may be useful in improving surgical skill and patient outcomes in cataract surgery. Future opportunities rely on taking advantage of technical improvements in simulators for education and research.

Randomized Controlled Trial
Defocus Incorporated Soft Contact (DISC) lens slows myopia progression in Hong Kong Chinese schoolchildren: a 2-year randomised clinical trial.
To determine if 'Defocus Incorporated Soft Contact' (DISC) lens wear slows childhood myopia progression. ⋯ The daily wearing of DISC lens significantly slowed myopia progression and axial elongation in Hong Kong schoolchildren. The findings demonstrated that simultaneous clear vision with constant myopic defocus can retard myopia progression.

To evaluate the diagnostic accuracy of methylene blue used as a non-invasive in vivo stain to detect ocular surface squamous neoplasia (OSSN). ⋯ The topical application of methylene blue is a simple, inexpensive, non-invasive diagnostic test that can be helpful in excluding malignant ocular surface lesions but cannot replace histology as gold standard for diagnosis of OSSN.

Comparative Study
Utilisation of an outpatient sedation unit in paediatric ophthalmology: safety and effectiveness of chloral hydrate in 1509 sedation episodes.
To report the largest study on the safety and effectiveness of sedation in paediatric ophthalmology in a nurse-led outpatient sedation unit. ⋯ CH sedation allows detailed examination and investigations in the majority of children with few side effects. Patients over 15 kg and need for a top up dose are risk factors for failure and adverse events. This is the largest study in the current literature looking at the use of CH sedation in ophthalmology and confirms its safety and effectiveness.

To identify patient-reported outcome measures (PROMs) specifically developed and used to assess the impact of ophthalmic disorders in children and to systematically assess their quality as a basis for recommendations about their use in clinical and research settings. ⋯ Paediatric ophthalmology PROM development and application is a developing field and new instruments are needed. There is scope for improvement in this area through (a) clarity of definitions of the underlying constructs intended to be measured at the onset of development of new instruments, (b) application of child-centred approaches and (c) adherence to extant guidance and best practice in questionnaire instrument development.
