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...
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...

aphakia, intraocular lens, scleral-sutured, suture breakage
This is a retrospective review of 392 consecutive cases in 349 patients who had scleral-sutured intraocular lens (IOL) due to aphakia, subluxated or luxated IOL, over a 10-year period in one centre from Barcelona. Preop and postop data were collected...

Bacterial contamination, contact lens, corneal collagen cross-linking, keratoconus, photorefractive keratotomy
Corneal collagen cross-linking (CCL) is a treatment modality that has been shown to stop the progression of keratoconus. There have also been reports that CCL acts as an antimicrobiologic agent in treating resistant microbial keratitis. This study aimed to investigate...
Wrong intraocular lens events – what lessons have we learned?
Data from wrong IOL patient safety incidents (PSIs) submitted to the National Reporting and Learning System (2010–2014) were reviewed and scrutinised by thematic analysis and compared with the historical data collected for groups in 2003-2010, prior to the mandatory checklist...
