Keratoconus as refractive surgery: Thinking outside the ‘cone’
June 15th 2016In this first of a two-part series, Arun C. Gulani, MD, MS, explains how approaching keratoconus as a refractive surgery will change the way both ophthalmologists and patients will approach this condition to bring in a new era of not only relieving but also enhancing the lifestyle of this patient population. In Part 2, Dr. Gulani will share strategies and cases of patients with keratoconus with different case scenarios in action.

IOLs in cataract surgery – do the risks outweigh the benefits in infants?
September 1st 2015This article presents recent epidemiological findings outlining the association between cataract surgery, potential visual acuity gains, glaucoma and the risk of undergoing additional general anaesthesia in under 2s. The authors of the original study concluded that use of IOLs in cataract surgery in young children should be critically reassessed, particularly in settings/communities where close, long-term follow-up is challenging.

The dexamethasone nanowafer: A novel method of drug delivery for dry eye disease
September 1st 2015This review presents a therapeutic nanowafer as an alternative to eye drops for dry eye disease, designed to enhance efficacy and improve patient compliance to treatment. In an experimental animal study, the novel dexamethasone nanowafer drug delivery system was comparable in efficacy to twice-daily dexamethasone eye drop treatment and has the potential to minimise risk of cataract formation and glaucoma.

CLE with latest generation of advanced multifocal implants
May 1st 2015The number of presbyopia correcting options has increased along with the size of the presbyopic market. Clear lens exchange (CLE) is becoming a popular option as a result of the latest generation of intraocular lenses that have been shown to offer spectacle independence to a high proportion of patients. In this article, Mr Chitkara presents the 1-year results of his small study evaluating CLE with implantation of the Diffractiva-aA lens.
