The sexist lens addressing cataract-induced blindness in women
Ninety percent of the world’s blind population resides in low-income, developing countries [1]. The primary cause of their blindness is cataract, a condition that is easily treatable and unnecessary. A cataract is the clouding of the eye’s lens, often resulting...Ophthalmic learning through the lens of cognitivism and constructivism
Learning in ophthalmology is multi-faceted, from understanding the fundamentals of eye anatomy and physiology to higher order skills such as performing cataract and vitreoretinal surgery. Having a strong foundation in the basics is a necessity for higher order knowledge synthesis,...75th Anniversary year of the first intraocular lens implant
The 29th of November 2024 marks the 75th anniversary of the first intraocular lens implant by our Founder, Sir Harold Ridley FRS. The United Kingdom & Ireland Society of Cataract & Refractive Surgeons (UKISCRS) is marking the event with a...
Squamous metaplasia of conjunctival epithelial cells with soft contact lens wear versus non-lens wearers
Conjunctiva is composed of non-squamous epithelial cells interspersed with goblet cells, which is a secretory epithelium. Squamous metaplasia is a transformation to non-secretory epithelium, ‘keratinised’ and enlargement of the conjunctival non-goblet cells and relatively shrunken nuclei are seen on impression...
Endothelial keratoplasty (EK) with anterior chamber intraocular lens (ACIOL) versus secondary posterior chamber lens (PCIOL)
This is a retrospective study of 82 eyes (23 ACIOL, 59 PCIOL) with a history of either pseudophakic (PBK) or aphakic (ABK) bullous keratopathy, who had descemet stripping automated endothelial keratoplasty (DSAEK) with retained or secondary ACIOL, or DSAEK with...
Intraocular Lens Surgery
This book is a valuable update on understanding IOL surgery for ophthalmologists in training and in practice. Broadly, the book is divided into six sections dealing with three main concepts: 1) IOL selection for routine and complex scenarios; 2) IOL...Rayner champions earlier conversations about cataract lens options
Cataract surgery is the most frequently performed operation in the UK, with an estimate of 960,000 procedures in 2026i. As demand continues to rise, so does the importance of helping patients understand the intraocular lens choices available to them. For...
DISC lens slow myopia progression in Hong Kong Chinese schoolchildren
This is a prospective double-blind randomised trial between September 2007 and October 2009. It included 221 children aged 8-13 years, with myopia between -1 and -5 Dioptres ≤1.00D. There were 111 patients in the defocus incorporated soft contact DISC group...
Oral omega-3 fatty acid treatment for dry eye in contact lens wearers
This study evaluates the effect of dietary omega-3 fatty acid supplementation of dry eye symptoms, tear film tests, and conjunctival impression cytology in patients with contact lens wear-associated dry eye. In this randomised double-blind, multi-centred trial, contact lens wearers (n=...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...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...
