Combined DIMS and low dose atropine for preclinical/early-stage myopia treatment in children

This retrospective study evaluated efficacy of multi zone positive optical defocus lenses (DIMS) and fog vision and 0.01% atropine for the treatment of children with preclinical and early stages of myopia. Children were included if aged 6–14 years, with spherical...

Changes to refractive error after surgery for congenital ptosis

In this study, the authors examined surgically induced refractive changes and changes in visual acuity after congenital ptosis surgery for 24 patients (16 males, 8 females) with age at surgery of 1.82 ±3.48 years and time from diagnosis to surgery...

Complex Biometry Clinics: a new service development

In this article we describe a new local service development, the ‘Complex Biometry Clinic’ at Leicester Royal Infirmary. Retrospective data analysis of patients referred between October 2012 and October 2013 was performed. The aim was to provide a one-stop service...

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...

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...

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...
