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...Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery

Cataract and Refractive
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...

Cataract and Refractive
This retrospective study used the American Academy of Ophthalmology Registry data to analyse the need of reoperation for realignment within the first year after cataract surgery with a TECNIS or AcrySof monofocal toric IOL implanted during 2016 and 2017. They...

Optical quality, cataract, intraocular lenses, monofocal, multifocal
It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...
How to diagnose and treat Acanthamoeba keratitis
Corneal ulceration caused by Acanthamoeba is on the rise, and recent publications indicate an outbreak in the UK over the last few years [1]. Since Acanthamoeba keratitis often presents with atypical features, diagnosis from slit-lamp examination alone can often be...Implantation of diffractive trifocal intraocular lens

Cataract and Refractive
This study reports on 60 eyes of 120 patients who underwent routine cataract surgery followed by implantation of the trifocal IOL model Lisa tri-839MP. This is a diffractive trifocal preloaded IOL with no interruption at the haptic-optic junction, 360 degrees...

The lens consists of a monolayer of epithelial cells that overlies fibre cells that differentiate from epithelial cells at the equator. While developing, fibre cells need mitochondria to provide energy, as they mature they lose these and other organelles to...

Cataract and Refractive
This study aimed to compare the outcomes of two diffractive trifocal intraocular lenses and one extended depth of focus (EDOF) intraocular lens (IOLs). This was a six month, single centred, prospective, randomised, comparative study in which patients who underwent routine...

Confocal microscopy, Corneal wound healing, Extracellular matrix, SHG imaging
Stromal keratocytes are responsible for wound healing in the cornea following damage. Keratocytes at the site of injury become activated and differentiate to myofibroblasts which secrete extracellular matrix (ECM) to close the wound, a response mediated by transforming growth factor...

Retina / Uvea / Vitreous
Confocal adaptive optics (AO) technology has enabled cellular level retinal imaging, including imaging of photoreceptors and blood flow. Adaptive optics scanning laser ophthalmoscopy (AOSLO) is a technology that provides high resolution and high contrast retinal images by correcting ocular aberrations....
