Principles of contact lens fitting in keratoconus
Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery
Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...Charles Bonnet Syndrome emerges from the shadows

Comparison of vision screening programmes
The purpose was to examine the treatment that children underwent as a result of being identified with reduced vision at school screening. The level of improvement in vision was identified and the time taken to achieve maximum visual acuity. There...Biotech Healthcare transforms lives through its CSR initiative, 'I See You'

Corneal Topography in Clinical Practice (Pentacam System)
This book is based upon one device, the Pentacam, developed by OCULUS, and is primarily aimed at those who wish to familiarise themselves with the Pentacam system and need a text to complement the instrument operations manual. It is laid...Newer generation IOL platforms designed for high-quality visual performance after cataract surgery
Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...
Fellow eye comparison of DMEK and PKP
This retrospective analysis of 11 patients who underwent penetrating keratoplasty (PKP) in their first eye followed by descemet membrane endothelial keratoplasty (DMEK) in their second eye studied visual and refractive outcomes. Intra and postoperative complications were compared and a subjective...
Does the length of the school day have a role in age of myopia onset?
The authors prospectively collected the refractive data of myopic adults attending recruiting dispensing optician or ophthalmologist sites. Participants were recruited consecutively, giving verbal informed consent. Sites included a mix of urban and rural areas across eight sites. The following data...The management of possibly progressive pterygium
