Sutureless 27-gauge needle intrascleral intraocular lens implantation

The authors report on a prospective, non-comparative, interventional case series of patients undergoing sutureless intrascleral fixation of a posterior chamber three piece intraocular lens (IOL) using a 27-gauge needle for docking. Sutureless techniques have the advantage of not having complex...

Non-contact-lens-associated acanthamoeba keratitis

This retrospective study was done to study the clinical presentation and microbiological results of non-contact-lens-related acanthamoeba keratitis (AK). One hundred and ninety-four patients with microbiological / histopathological diagnosis of AK over four years were included. All patients had corneal scrapings...

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...

Orthokeratology lens treatment for exophoria of convergence insufficiency type

The purpose of this study was to evaluate the effectiveness of orthokeratology (OK) lenses with an increased comparison factor (ICF) of 1.75D in the treatment convergence insufficiency (CI) exophoria (EP). This was a prospective, self-controlled study of 60 eyes (30...

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...

Blame the lens – not its position – in refractive surprise

Aetiology of postoperative refractive surprise Weber coined the term “wrong eye, wrong intraocular lens, wrong patient” in 2008 as an aide memoir of major factors believed to underlie refractive surprise – defined as a significant unintended difference between dioptric refraction...

Cutaneous malignant melanoma metastasis to pseudophakic lens

Metastases to the eye and orbit are rare and intraocular cutaneous malignant melanoma metastasis (ICMM) is exceedingly rare, representing around 5%. There have only been three previous cases of ICMM to the lens in the literature, all of which presented...

Accuracy of intraocular lens power calculations in paediatric eyes

A study comparing the accuracy of the SRK II, SRK/T, Hoffer Q, Holladay 1, T2 and Super formula in predictive refractive outcomes in children undergoing primary IOL insertion into the capsular bag following cataract surgery. A total of 377 eyes...

Risk factors for lens dislocation post cataract surgery

This retrospective cohort study in Korea assessed the risk factors for intraocular lens (IOL) dislocation. They used national data of 2,162,191 patients who had had cataract surgery between 2009 and 2016. They excluded any patient who had an IOL dislocation...

Survey of parental experience of contact lens support

In this study, the service under evaluation is for paediatric aphakia patients. Soft contact lenses (CLs) are inserted at the time of surgery and remain in-situ for the immediate postoperative period. The aim is for families to undertake daily CLs...

EDOF intraocular lens in eyes with preexisting retinal disease

Extended depth of focus (EDOF) intraocular lens (IOL) offers improved near and intermediate vision, aiming to reduce spectacle dependence in cataract patients. This study aims to evaluate the performance of EDOF lenses following cataract surgery in patients with retinal pathology....

Prismatic contact lens correction vs prismatic glasses

The aim of this study was to verify if diplopia could be corrected by applying soft directional prism contact lenses, to compare effectiveness of diplopia correction, comfort and quality of vision with these contact lenses compared to prism glasses. This...
