Simple approach to prevent capsule tear-out during capsulorhexis creation in hyper mature cataracts

Puncturing the anterior capsule in the anterior chamber so that the pressure falls below intracapsular tension causes the rhexis to extend out to the equator. If this develops into a tear that wraps around the entire lens it is called...

Effectiveness of Eagles Eye Mobile

The EEM programme was created to target children failing school nurse screening and likely to not have access to eye care. The EEM visits schools in low income areas providing optometric examinations to detect correctable refractive error, prescribe and deliver...

Toric intraocular lens rotation related to the capsulorrhexis

The risk factors for postoperative rotation in the early post-operative period; a longer axial length, younger patients, and with the rule astigmatism as described by Miyake T et al. (JCRS 2014) in a case series of six eyes. This letter...

Influence of overall intraocular lens diameter on rotational stability

It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...

Orthoptic Cochrane reviews

The purpose of this study was to explore the Cochrane Eyes and Vision (CEV) library to extract and overview protocols and systematic reviews of relevance to orthoptic practice. A full database search was made of the 2016 library. Twenty-seven systematic...

Postoperative astigmatism

The authors investigate the short and long-term postoperative refractive effects of medial rectus recession on the involved eye and explain the detectable effects in detail by the results of vector analysis in 52 eyes and 32 patients. The subjects had...

Comparison of photoscreeners

The purpose of this study was to apply the GoCheckKids, iScreen, PlusoptiX and SPOT to young patients and developmentally challenged patients in a paediatric eye practice. One hundred and eight children were assessed with a mean age of 47 months...

Cost-effectiveness of femtosecond cataract surgery

Femtosecond laser-assisted cataract surgery has become increasingly popular due to the reported benefits of increasing precision and reproducibility of capsulorrhexis, less power and manipulation required during phacoemulsification, better corneal wound architecture, and the ability to place precise arcuate keratotomy incisions...

High-fluence collagen cross-linking

The authors treat seven eyes with progressive keratoconus with a high energy (18mW) for five minutes delivering a total energy similar to that suggested by the original Dresden protocol (3mW for 30mins). All eyes had a thickness >400µm following epithelial...

Progression of high anisometropia in children

This study aimed to analyse the stability and progression of higher degrees of myopic anisometropic in children. This retrospective study included 63 children meeting the inclusion criteria. Mean age at initial visit was 4.3 years ±2. There were 51% males...

Quality of esotropia referrals

The purpose was to examine the quality of referrals made for children with esotropia and to evaluate management offered prior to referral. This retrospective study identified 326 children with esotropia aged less than five years and referred over a period...

The global burden of age-related macular degeneration

Age-related macular degeneration (AMD) is the third leading cause of blindness (behind cataract and refractive error). The authors present the results of the Global Burden of Disease (GBD) 2015 study, which included 195 countries. The disability-adjusted life years (DALY) due...
