Is lens constant optimisation for IOLMaster indispensable in order to achieve a good refractive outcome?

A study of refractive outcomes following cataract surgery was carried out with the aim of comparing the postoperative refractive outcomes against Royal College of Ophthalmologists standards and to determine the extent of association between accuracy of intraocular lens (IOL) power...

Burning vision: vision loss from misuse of ‘toy’ laser pens in children

A case series of five children with macular burns due to the misuse of novelty laser products, purchased online or abroad, was undertaken at the Royal Hallamshire Hospital and The Children’s Hospital, Sheffield [1]. All patients were from the Sheffield...

Paediatric ptosis

Manoj Parulekar and colleagues provide a comprehensive overview of the diagnosis, assessment and management of childhood ptosis. Blepharoptosis (commonly referred to as ptosis – Greek, πτῶσις, ‘to fall’) is a condition where the upper eyelid is in an abnormally low...

Newer generation IOL platforms designed for high-quality visual performance after cataract surgery

Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...

Herpes zoster ophthalmicus: the essentials

Herpes zoster, also referred to as shingles, is a common infection most typically caused by the reactivation of varicella zoster virus that lies dormant (sometime for decades) in the dorsal root nerve ganglion following primary chickenpox infection [1]. In 10-20%...

Possible COVID-19 related maculopathy

COVID-19 is being investigated as a potential cause for various ocular diseases, with growing evidence of related retinal vascular changes, that vary from isolated cotton wool spots and retinal haemorrhages to retinal vascular occlusions [1.2]. COVID-related macular affection has also...

Understanding spaceflight-associated neuro-ocular syndrome (SANS): what do we know?

Introduction Formerly known as visual impairment and intracranial pressure syndrome (VIIP), space-related neuro-ocular syndrome (SANS) is defined by a collection of ophthalmic and neurological findings in astronauts after long-term spaceflight [1]. Changes in the eyeball, such as hyperopic shift, during...

Comparison of corneal deformation parameters in keratoconic and normal eyes

This study set out to compare biomechanical properties between normal and keratoconic eyes. It was a retrospective study evaluating 89 eyes (47 normal, 42 keratoconic) and a validation arm of 72 eyes (33 normal, 39 keratoconic) using a high speed...

Management of diabetic macular oedema (DMO)

The authors present guidelines on current diagnostic and therapeutic procedures in the management of DMO. Fluorescein angiography (FA) and optical coherence tomography (OCT) are recommended before starting treatment to help diagnose and stage DMO, and can be repeated if there...

Ocular complications in retinal vasculitis

In this retrospective study the authors aimed to characterise the incidence rates of visual loss and ocular complications associated with retinal vasculitis (RV – annual incidence of 1-2/ 100000/ per annum). A secondary objective was to compare the visual outcomes...

The natural history of treatment naïve choroidal neovascularisation (CNV) in geographic atrophy

The aim of this retrospective study is to assess the characteristics and natural history of quiescent CNV in geographic atrophy (GA) utilising multi-modal imaging. Case notes were reviewed of patients diagnosed with geographic atrophy between January 2010 and December 2016...

Effects of phacoemulsification on IOP and drug use in glaucoma

For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the...
