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....

Is laser refractive surgery safe for patients taking isotretinoin?

This multicentre, retrospective, interventional case series assesses the outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in 113 patients taking isotretinoin between January 2003 and September 2017. Isotretinoin is contraindicated for LASIK and PRK and patients are...

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...

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...

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

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....
