An unusual case of silicone oil in the anterior chamber simulating intraocular implant

Silicone oil internal tamponade has been used for over 50 years, even prior to pars plana vitrectomy [1].Over a course of time silicone oil may migrate to the anterior chamber through the pupil. This may disperse in the form of...

Refractive surprise after cataract surgery caused by posterior capsular striae

Cataract removal with intraocular lens (IOL) implantation is one of the most frequently performed surgeries in current clinical practice [1,2]. New microsurgical techniques and refined IOL power calculations allow excellent refractive outcomes. Refractive surprise following cataract surgery is uncommon [1-3]...

Melkersson-Rosenthal syndrome

Melkersson-Rosenthal syndrome (MRS) is a rare neuro-mucocutaneous disorder which is defined by a triad of orofacial oedema, furrowing of the tongue, and recurrent episodes of facial nerve palsy [1]. Due to the rarity of the disease and inconsistent presentation, MRS...

Emerging developments in dry eye

An estimated 344 million people worldwide suffer from dry eye [1]. This chronic syndrome is characterised by a vicious cycle of tear film hyperosmolarity, tear instability and corneal stress, leading to increased friction, inflammation, ocular surface damage and decreased visual...

Identifying drugs associated with intraoperative floppy iris syndrome

Before David Chang MD from the University of California found out about intraoperative floppy iris syndrome (IFIS), ophthalmologists were mystified each time they came across cataract surgeries that were characterised by sudden intraoperative iris prolapse and pupil constriction. The biggest...

Open source and tele-manufacturing for ophthalmology

Open source or crowd-sourcing and crowd-collaboration are concepts almost always associated with software and public online projects such as Wiki project. Never had I imagined that my team would apply the same principle in ophthalmology. Just less than a month...

Ground-breaking achievements in blindness prevention

One small UK based charity is enabling pioneering research to prevent blindness in low and lower middle income countries. The British Council for Prevention of Blindness (BCPB), established in 1976, funds innovative research and training which seeds the development of...

Designing ophthalmology services - Part 1: How do we address the queues in a clinic?

This first of a three-part series shows how systems engineering can be used to correctly diagnose and address the causes of delays in a clinic. The second article, which will be featured in the April/May 2020 issue, describes how to...

Pioneering eye device restores reading vision to blind eyes

A pivotal European clinical trial of a new electronic eye implant has seen remarkable results. The study, published in the New England Journal of Medicine, showed 84% of participants were able to read letters, numbers and words using prosthetic vision...

Applying for ophthalmology ST1 in 2026: What’s new?

Competition for ophthalmology ST1 has intensified steadily over recent cycles, rising from ~9:1 (2022) to ~10:1 (2023), ~14:1 (2024) and ~22:1 (2025) [1]. Against this background, applicants benefit from a structured approach: mapping achievements to portfolio domains early, identifying gaps...

A look into the IOL space

Advances in the design and performance of intraocular lenses (IOLs) continue to be driven by demand for better outcomes, presbyopia correction and spectacle independence, alongside a better understanding of the dynamics of the crystalline lens, newer theories of accommodation and...

Neovascular AMD: fresh recommendations underline standards of best practice

The management of neovascular age-related macular degeneration (nAMD) has advanced dramatically over the past seven years, with the introduction of targeted new therapies that successfully maintain or improve vision in a majority of affected individuals. It’s a fast moving field,...
