Comparison of SIA from femtosecond laser and manual CCIs for cataract surgery

This study group compared the differences in surgically induced astigmatism (SIA) vector, flattening effect, torque and wound architecture following both femtosecond laser and manual clear corneal incisions (CCIs). A double-armed, randomised, prospective case series was conducted. Cataract surgery was performed...

MR- vs. LR+ for divergence insufficiency

A retrospective study was conducted to compare the efficacy of medial rectus recession and lateral rectus resection as surgical interventions for divergence insufficiency in 18 patients. These were cases of non-neurological cause. Two patients in each group required postoperative adjustment....

Pituitary tumours: why are they so often missed?

Part 2: Clinical varieties, anatomical considerations and case report (see also Part 1 and Part 3) For ophthalmologists there are four types of pituitary tumour to be considered, three of which are named according to the hormone secreted, along with...

Amnion-assisted conjunctival epithelial redirection (ACER): Enhancing stem cell transplantation treatment of total limbal stem cell deficiency

An exploration of Professor Harminder Dua’s recent work using a technique called amnion-assisted conjunctival epithelial redirection (ACER) to aid the success of conjunctival-limbal grafting procedures. ACER provides a refined way to use amniotic membrane (amnion), such as Omnigen® (NuVision® Biotherapies,...

“Robot performs cataract surgery on patient!”

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are scientific reality and which are ‘fake news’. Headline: “Robot performs cataract surgery on patient!” Twenty-five years ago when Eye News launched, a news headline such...

Real-world experience and outcomes of SLT laser used as a first-line treatment in ocular hypertension patients in a United Kingdom National Health Service setting

The management of raised intraocular pressure (IOP) in the context of ocular hypertension (OHT) and primary open angle glaucoma (POAG) remains a major contributor to the workload of ophthalmology units across the UK. Treatment of these conditions has historically centred...

The art of ophthalmic simulations

For Dec/Jan 2024, I got in touch with Nicky Webster, a Principal 3D Artist at FundamentalVR (https://fundamentalsurgery.com). Nicky is also a registered medical illustrator, healthcare scientist and medical photographer. With over 18 years of experience working in various disciplines within...

Scheimpflug images and graft rejection

This study aimed to assess corneal changes using 360-degree Scheimpflug images and pachymetry readings to outline screening parameters, which define graft rejection. Seventeen eyes of 16 patients developed clinically manifest allograft rejection two to 42 months after surgery – those...

Influence of overall intraocular lens diameter on rotational stability

It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...

The results of the last survey Jun24

When I was in my training and even in my early years as a consultant, I did not fully understand the difference between different lenses. When asked my preference of hydrophilic versus hydrophobic intraocular lenses (IOLs) I really did not...

The refractive index in the eye lens – implications for clinical practice and optical design

The eye may appear to be a comparatively simple organ and yet its optical system is complex and continues to be a source of investigation and research. The major optical elements are considered to be the cornea and the lens...

MicroRNA mediate retinoblastoma signal transduction

MicroRNAs (miR) are small non-coding single-stranded RNA molecules, normally 22 nucleotides long. There is a large family of miR that control protein expression by binding to mRNAs, leading to their degradation. One important role of miR is in tumours where...
