Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

Predicting ischemic lesion location using perimetry

The authors present a retrospective records review, using the search terms homonymous hemianopia, visual field loss and MRI. Only posterior circulation artery territory ischemic strokes were included. Demographics, stroke details and initial and follow-up with 24-2 SITA Standard perimetry results...

“Beware of the pigment”

Using some captivating artwork, Iheukwumere Duru describes key features of pigment dispersion syndrome. Pigmentary dispersion syndrome (PDS) leads to pigmentary glaucoma (PG) in approximately 35-50% of patients with the condition [1]. PG is the leading cause of non-traumatic blindness in...

Temporal versus nasal clear corneal incisions

This is a prospective randomised study of 100 patients’ left eye having undergone phacoemulsification either by a 2.4mm nasal clear corneal incision (CCI) group or temporal CCI group. The corneal astigmatic changes were compared between groups by power vector analysis,...

Cataract Advanced Training with Simulation (CATS)

This course focuses on advanced cataract surgery skills including the management of posterior capsule rupture, zonular weakness, small pupils, and secondary and toric IOL implantation. The course programme is designed to deliver an immersive hands-on experience using high-fidelity simulation technology...

Choroidal and retinal vascular changes after horizontal rectus surgery

The authors used wide field swept-source OCT angiography (SSOCTA) to evaluate changes in retinal and choroidal blood flow before and after horizontal rectus muscle surgery. They aimed to characterise the haemodynamic impact of extraocular muscle surgery on the posterior pole...

Delayed angle closure in pseudophakia and repeated intravitreal therapy

The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...

Implantation of diffractive trifocal intraocular lens

This study reports on 60 eyes of 120 patients who underwent routine cataract surgery followed by implantation of the trifocal IOL model Lisa tri-839MP. This is a diffractive trifocal preloaded IOL with no interruption at the haptic-optic junction, 360 degrees...

Systemic anti-inflammatory versus fluocinolone acetonide intraocular implant

In the Multicenter Uveitis Steroid Treatment (MUST) trial, 255 patients with intermediate uveitis, posterior uveitis or panuveitis were randomised to either fluocinolone acetonide intraocular implant or systemic corticosteroid therapy which was supplemented with immunosuppression if required. Patients were followed up...

Meta-analysis of HLA B27 associated acute anterior uveitis

A literature-based meta-analysis was carried out to look at the various clinical features associated with HLA- B27 acute anterior uveitis (AAU). After an extensive search of literature for HLA B27 uveitis was conducted, 735 results were obtained. Twenty-nine articles were...

Does lower eyelid entropion repair alter corneal topography?

The authors aimed to analyse the corneal morphology before and after advancement of posterior lower eyelid retractors (LERs) alone or in combination with a lateral tarsal strip (LTS) for lower eyelid involutional entropion. Retrospective analysis of 24 consecutive elderly patients...
