Scheimpflug imaging in paediatric glaucoma

The authors undertook this study to report the corneal tomographic characteristics of eyes that had surgery for controlled primary congenital glaucoma (PCG) compared to a control group. The study included 44 eyes of 27 children (18 males) having surgery for...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Secondary intraocular lens implantation in children

This is a retrospective study of the medical records of children under the age of 16 who underwent secondary lens implantation for aphakic corrections after previous congenital cataract surgery over a period between January 2000 and December 2010. The study...

EDTA chelation for band keratopathy

The authors describe a retrospective analysis of 89 eyes from 72 patients who underwent ethlenediamine tetra-acetic acid (EDTA) chelation for band keratopathy. The ratio of R:L eye was 41:48. The mean age was 71 years (range 18-93 years). Thirty-two out...

Corneal tattooing as treatment for bullous keratopathy

This retrospective study looked at differences in epithelial smoothing in patients with bullous keratopathy (BK) undergoing either corneal tattooing or anterior stromal puncture (ASP). Both procedures were carried out for symptomatic relief in eyes with poor visual potential. Chinese ink...

Topography-guided photorefractive keratectomy in the treatment of corneal scarring

This study reports the outcome of topography-guided photorefractive keratectomy (TG-PRK) in the treatment of patients with corneal scarring. A retrospective case series including six eyes of six patients with corneal scarring and irregular astigmatism who underwent topography guided PRK. The...

Effect of topical diclofenac on postoperative PRK pain: RCT

A major disadvantage of excimer laser photorefractive keratectomy (PRK) is pain and discomfort after the surgery, which is thought to be due to damage to corneal sensory nerve fibres or local release of inflammatory substances. Pain only resolves once corneal...

A phase 3 randomised trial of nicotinamide for skin cancer chemoprevention

To B3, or not to B3? That was the question asked in this controlled trial in which the authors were able to show that oral nicotinamide (vitamin B3) is able to reduce further skin cancer development in high risk patients....

Does lower eyelid entropion repair alter corneal topography?

The authors aimed to analyse the corneal morphology before and after advancement of posterior lower eyelid retractors (LERs) alone or in combination with a lateral tarsal strip (LTS) for lower eyelid involutional entropion. Retrospective analysis of 24 consecutive elderly patients...

Laser corneal refractive procedures – a review

Evolution of refractive surgery stays true to the quote of Theodore Roosevelt: “The more you know about the past, the better prepared you are for the future.” Refractive surgery is an evolving field, which thanks modern technologies for refining ideas...

Outcomes of corneal collagen crosslinking (CXL) in pseudophakic bullous keratopathy (PBK)

This was a retrospective non-comparative, interventional case series of 50 eyes in 50 patients with symptomatic PBK who underwent CXL (epithelium-off). Central corneal thickness (CCT), pain score, best corrected visual acuity (BCVA), and corneal transparency were recorded at baseline; at...

LASEK vs. epi-LASIK for myopia: meta-analysis

Previous studies have produced inconsistent conclusions on the relative benefits between LASEK vs. Epi-LASIK. LASEK uses 20% alcohol to separate an epithelial flap from the Bowman membrane. After ablation, the epithelial flap is repositioned onto the cornea. Epi-LASIK creates the...
