Outcomes of primary and repeat DSAEKs

Retrospective analysis of results following primary and secondary descemet stripping automated endothelial keratoplasty (DSAEKs), carried out in Villa Serena-Villa Igea Private Hospitals in Italy, showed that primary and secondary DSAEK surgery result in similar visual outcomes, refractive errors and endothelial...

Acanthamoeba ability to adhere to different contact lenses

This study tested ability of Acanthamoeba lugdunensis trophozoites to adhere to silicon hydrogel contact lenses (SHCL) and how this is influenced by different multipurpose contact lens solutions (MPS). Three generations of SHCL were tested: first generation – Air Optix, second...

Dry eyes after photorefractive keratoplasty

This study examined changes in tear break up time (TBUT), Schirmer test, tear osmolarity and dry eye questionnaire (OSDI) score from prior to photorefractive keratoplasty (PRK), to two months and four months postoperatively. Fifty eyes of 25 patients were examined....

Familial Mediterranean Fever and keratoconus

This retrospective case control study was conducted in the Genetic Diagnostic Centre in Turkey. It examined the prevalence of keratoconus in two groups; patients with Familial Mediterranean Fever (FMF) and age matched controls free of FMF, who were tested for...

Surgical complications of ReLEx

Femtosecond laser refractive lenticule extraction (ReLEx) is a novel procedure for treatment of myopia and myopic astigmatism, which eliminates the use of microkeratome and excimer laser. Currently there are two techniques: FLEx – femtosecond lenticule extraction (similar to conventional LASIK)...

How to achieve 1% solution of Lissamine green

Lissamine green (LG) concentration of 1% is clinically effective in the diagnosis of ocular surface disease. LG is now commercially available only in a form of dye-impregnated strips, whose concentration is insufficient. This study examined how to achieve 1% concentration...

Cyclosporine A and pterygium fibroblasts

The matrix metalloproteinases (MMP) are a family of structurally related zinc-dependent extracellular matrix degrading proteinases that have been implicated in facilitating the migration and growth of pterygia. Both MMP- 3 and MMP-13 were found to be overexpressed in the fibroblasts...

Postoperative astigmatism

The authors investigate the short and long-term postoperative refractive effects of medial rectus recession on the involved eye and explain the detectable effects in detail by the results of vector analysis in 52 eyes and 32 patients. The subjects had...

Meibomian gland dropout in patients with dry eyes

In this prospective study 264 patients with symptoms of dry eye were examined with a non-contact meibography system to assess the morphological changes in their meibomian glands. These patients were not previously diagnosed with meibomian gland dysfunction and patients with...

Preoperative povidone iodine: weighing the risks

Following on from our recent online survey, the authors examine the potential risks and benefits of diluting the concentration preoperative povidone iodine. Povidone iodine (PI) is an iodophore that has an established use as a broad-spectrum antiseptic, mainly for the...

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...

The results of the last survey Aug22

The first question really highlights how we can become enshrined in the way we do things. I genuinely thought that everyone was using a cohesive viscoelastic for their cataract surgery. It was what I was taught, and I believe everyone...
