Post-cataract eye drops can be avoided by depot steroid injections.

There are over 400 000 cataract operations now being performed annually in the UK. With the majority of those patients being older people, comorbidities such as dementia or arthritis can prevent patients putting in their own post-operative eye drops. Where there is a lack of family or other support, district nursing services are often called upon to administer these eye drops, which are typically prescribed four times a day for 4 weeks, thus potentially totalling 112 visits for drop instillation per patient. To reduce the burden of these post-operative eye drops on district nursing services, administration of an intra-operative sub-Tenon's depot steroid injection is possible for cataract patients who then do not require any post-operative drop instillation. As a trial of this practice, 16 such patients were injected in one year, thus providing a reduction of 1792 in the number of visits requested. Taking an estimated cost of each district nurse visit of £38, this shift in practice potentially saved more than £68 000; the additional cost of the injection over the cost of eye drops was just £8.80 for the year. This practice presents an opportunity to protect valuable community nursing resources, but advocacy for change in practice would be needed with secondary care, or via commissioners

Overcoming challenges in the UK's National Health Service.

Working in an eye clinic in Dewsbury, West Yorkshire (with its large South Asian migrant population) in the 1990s, Andy Cassels-Brown noticed the large number of young South Asian patients who presented with much more advanced keratoconus than their Caucasian counterparts, who tended to be detected much earlier. This indicated an inequality in access to eye care services which, we discovered, was made worse as the Asian patients frequently had preventable associated allergic conditions (such as allergic conjunctivitis or eczema) and a strikingly strong family history of keratoconus. Better access to eye care would permit earlier identification of family members with the condition and, these days, prevention of progression by means of cross-linking to stabilise the keratoconic cornea

The Royal College of Ophthalmologists' National Ophthalmology Database study of cataract surgery: Report 7, immediate sequential bilateral cataract surgery in the UK: Current practice and patient selection.

BACKGROUND: Cataract extraction is the most frequently performed surgical intervention in the world and demand is rising due to an ageing demography. One option to address this challenge is to offer selected patients immediate sequential bilateral cataract surgery (ISBCS). This study aims to investigate patient and operative characteristics for ISBCS and delayed bilateral cataract surgery (DSCS) in the UK. METHODS: Data were analysed from the Royal College of Ophthalmologists' National Ophthalmology Database Audit (NOD) of cataract surgery. Eligible patients were those undergoing bilateral cataract extraction from centres with a record of at least one ISBCS operation between 01/04/2010 and 31/08/2018. Variable frequency comparison was undertaken with chi-square tests. RESULTS: During the study period, 1073 patients had ISBCS and 248,341 DSCS from 73 centres. A higher proportion of ISBCS patients were unable to lie flat (11.3% vs. 1.8%; p < 0.001), unable to cooperate (9.7% vs. 2.7%; p < 0.001); underwent general anaesthesia (58.7% vs. 6.6% (p < 0.001)); had brunescent/white/mature cataracts (odds ratio (OR) 5.118); no fundal view/vitreous opacities (OR 8.381); had worse pre-operative acuity 0.60 LogMAR ISBCS vs. 0.50 (first) and 0.40 (second eye) DSCS and were younger (mean ages, 71.5 vs. 75.6 years; p < 0.001). Posterior capsular rupture (PCR) rates adjusted for case complexity were comparable (0.98% ISBCS and 0.78% DSCS). CONCLUSIONS: ISBCS was performed on younger patients, with difficulty cooperating and lying flat, worse pre-operative vision, higher rates of known PCR risk factors and more frequent use of general anaesthesia than DSCS in centres recorded on NOD

Prevalence of blindness and distance vision impairment in the Gambia across three decades of eye health programming.

BACKGROUND/AIMS: The 1986 Gambia National Eye Health Survey provided baseline data for a National Eye Health Programme. A second survey in 1996 evaluated changes in population eye health a decade later. We completed a third survey in 2019, to determine the current state of population eye health, considering service developments and demographic change. METHODS: We estimated prevalence and causes of vision impairment (VI) in a nationally representative population-based sample of adults 35 years and older. We used multistage cluster random sampling to sample 10 800 adults 35 and above in 360 clusters of 30. We measured monocular distance visual acuity (uncorrected and with available correction) using Peek Acuity. Participants with either eye uncorrected or presenting (with available correction) acuity <6/12 were retested with pinhole and refraction, and dilated exams were completed on all eyes by ophthalmologists using a direct ophthalmoscope, slit lamp and 90 D lens. RESULTS: We examined 9188 participants (response rate 83%). The 2013 census age-sex adjusted prevalence of blindness (presenting acuity<3/60 in better seeing eye) was 1.2% (95% CI 0.9 to 1.4) and of moderate or severe VI (MSVI,<6/18 to ≥3/60) was 8.9% (95% CI 9.1 to 9.7). Prevalence of all distance VI (<6/12) was 13.4% (12.4-14.4). Compared with 1996, the relative risk of blindness decreased (risk ratio 0.7, 95% CI 0.5 to 1.0) and MSVI increased (risk ratio 1.5, 95% CI 1.2 to 0.17). CONCLUSION: Significant progress has been made to reduce blindness and increase access to eye health across the Gambia, with further work is needed to decrease the risk of MSVI

Clinical case study

With increasing international travel it is important that ophthalmologists become familiar with the various ocular presentations of infectious diseases, which untreated can cause serious morbidity and mortality

The Green Print: Advancement of Environmental Sustainability in Healthcare

Healthcare is a major emitter of environmental pollutants that adversely affect health. Within the healthcare community, awareness of these effects is low, and recognition of the duty to address them is only beginning to gain traction. Healthcare sustainability science explores dimensions of resource consumption and environmental emissions associated with healthcare activities. This emerging field provides tools and metrics to quantify the unintended consequences of healthcare delivery and evaluate effective approaches that improve patient safety while protecting public health. This narrative review describes the scope of healthcare sustainability research, identifies knowledge gaps, introduces a framework for applications of existing research methods and tools to the healthcare context, and establishes research priorities to improve the environmental performance of healthcare services. The framework was developed through review of the current state of healthcare sustainability science and expert consensus by the Working Group for Environmental Sustainability in Clinical Care. Key recommendations include: development of a comprehensive life cycle inventory database for medical devices and drugs; application of standardized sustainability performance metrics at the clinician, hospital/health system, and national levels; revision of infection control standards driving non-evidence-based uptake of single-use disposable devices; call for increased federal research funding; and formation of a Global Commission on the Advancement of Environmental Sustainability in Healthcare. There is an urgent need for research that informs policy and practice to address the public health crisis arising from healthcare pollution. A transformational vision is required to align research priorities to achieve a sustainable healthcare system that advances quality, safety and value
