Spherical aberration is a term often used in ophthalmology and optometry, especially in relation to lens surgeries and intraocular lens design. Recently, IOL manufacturers have been manipulating spherical aberration as a tool to provide a greater range of vision, but rarely explaining the mechanism. Your OATR hosts, Dr Nick Andrew and Dr Ben LaHood…

Disassembling the lens nucleus is a crucial step during cataract surgery. Different techniques may be better suited to different cataract types, require more skill and ultimately make a difference in visual recovery and corneal health. Your Ophthalmology Against The Rule hosts take a detailed look at the MiLoop technique and discuss the pros and co…

Ophthalmologists are performing cataract and refractive lens exchange surgery in younger patients. One of the major risks that eye care professionals need to inform these patients about is retinal detachment yet the evidence to quote from has been scarce and confusing. How age, axial length, gender, and laser capsuotomy, impact the risk needs to be…

Antiseptic preparation of the eye is an absolutely vital step of cataract surgery in order to prevent infection. This treatment must be balanced with minimising harm to the ocular surface. In true OATR style, we take a detailed look at the pros and cons of traditional iodine and more modern chlorhexidine antiseptic solutions. Getting these seemingl…

Treating dry eye disease is difficult. Trying to treat dry eye disease based on evidence can seem even harder. Omega-3 fatty acid supplements have been on a rollercoaster of popularity in treating dry eye. Evidence appeared to swing from indicating huge benefit to being similar to placebo. Your hosts, Dr Ben LaHood and Dr Nick Andrew analyse the ke…

Oh, you thought we were finished talking about narrow angles? We were just getting warmed up! In this OATR episode, your hosts Dr Ben LaHood and Dr Nick Andrew provide practical tips on interventions for treating narrow angles. Everything from tips on laser iridotomy to IOL calculation in short eyes. Part of our motto is "the simple things often ov…

OATR Season 2 is launched with everything you ever wanted to know about narrow angles. We had a lot to catch up on so if you're short on time, the main topic starts at 28 minutes! We received so many questions about narrow angles and glaucoma, cataract surgery, iridotomies and more that it was time your hosts Dr Ben LaHood and Dr Nick Andrew covere…

OATR is back for 2021 and we are kicking things off in style with everyone's favourite topic - astigmatism! There are a lot of rumours, myths and arguments around the topic of residual astigmatism after cataract surgery. Some say it gives a depth of focus; that it may be functionally beneficial; or that you can't do much about it as you should not …

Myopia progression is a major concern in the worlds of optometry, ophthalmology and the world in general with a predicted 5 billion people being myopic by 2050. The concern is not just needing glasses, but retinal detachment, myopic macula degeneration and blindness. The evidence for how to slow down myopia progression, especially around atropine d…

Your Ophthalmology Against The Rule hosts bring you everything you ever wanted to know about PCO from prevention during cataract surgery, influences of IOL design and surgery technique, through to management with YAG posterior capsulotomy. This topic will be of interest to optometrists and ophthalmologists as capsule opacity is a common reason for …

Angle Kappa is one of those terms that gets thrown about at every ophthalmology meeting but does anyone really know what it means, what to do with that information or even what angle kappa really is? Your Ophthalmology Against The Rule hosts explain in simple language everything you want or need to know about angle kappa. They also discuss the real…

Your OATR hosts discuss the pros and cons of using OCT of the Disc and OCT of the Macula for detecting, monitoring and making treatment decisions in glaucoma. Looking after glaucoma patients used to involve a visual field and disc photos. OCT of the disc and nerve fibre layer revolutionised management. Now, OCT of the ganglion cell layers at the ma…

It is high time that your Ophthalmology Against The Rule hosts Dr Ben LaHood and Dr Nick Andrew looked at the case for medical marijuana in ophthalmology. The ability of marijuana to lower intraocular pressure is well known but is it ready to be used as a routine glaucoma medication? Let us inhale all the evidence on this controversial topic and pr…

Your Ophthalmology Against The Rule hosts Dr Ben LaHood and Dr Nick Andrew discuss the latest evidence and their views on refining the outcome of second eye cataract surgery. Modern IOL calculation formulae are very good at predicting a refractive outcome but not yet perfect. Can we improve any further by considering how the first eye responded to …

Ocular dominance is a term that often is thrown around when thinking about cataract and laser surgery, especially with regards to monovision. Despite this, testing of ocular dominance is often poorly understood and performed. This can lead to post-operative headaches - literally! In this episode of Ophthalmology Against The Rule, we discuss the str…

Your hosts of Ophthalmology Against The Rule, Dr Ben LaHood and Dr Nick Andrew take a deep look at the evidence for and against different wavelength filtering IOL options. Some higher energy wavelengths of light potentially can be detrimental to macula health, cause glare and affect sleep. Available IOL technology now offers surgeons the ability to…

We conclude our Ophthalmology Against The Rule miniseries on surgically induced astigmatism (SIA) by discussing the concepts of internal astigmatism, posterior corneal astigmatism, IOL tilt and decentration. Total SIA or internal SIA are commonly spoken terms but not often discussed or defined. We shed some light on what they are all about and whet…

In part two of this Ophthalmology Against The Rule miniseries on surgically induced astigmatism (SIA), Dr Ben LaHood and Dr Nick Andrew discuss the practicalities of assessing and calculating SIA for each surgeon. This includes what measures are needed, when to measure and tools to give you all those numbers you read about in the journals.…

On this special episode Dr Ben LaHood and Dr Nick Andrew discuss COVID19 for eye care professionals and cover specifically what ophthalmologists and optometrists can do to keep themselves and their patients safe during the pandemic.By Dr Ben LaHood and Dr Nick Andrew

Surgically Induced Astigmatism (SIA) is a poorly understood part of every cataract surgery and IOL calculation. Understanding, minimising and making SIA more consistent can lead to more predictable refractive outcomes. In the first part of this three part mini-series we get down to basics with understanding exactly what SIA is all about.…
