An Introduction to Cataract Surgery
Cataract surgery is one of the most common surgical procedures globally, and the numerous advances over recent years have helped to improve patient outcomes. Femtosecond laser-assisted cataract surgery (FLACS) introduced surgeons to a new non-invasive technique with high reproducibility compared with conventional procedures. Innovations in IOL technology, including most recently the introduction of extended depth of focus lenses and accommodating IOLs, offer more options for patients and better refractive outcomes along with shorter recovery times.

Current Challenges in the Postoperative Management of Cataract Surgery

Cataract interventions are among the most common surgical procedures performed worldwide, in developed or developing countries.1 In 2015, approximately 3.6 million cataract interventions were performed in the United States.2 In the next few years, age-related diseases are likely to rise in many nations with increasing life expectancy, and cataracts will become more common. Cataract surgery […]
Five Pearls for Long Eyes
touchREVIEWS in Ophthalmology. 2021; 15(1):2–5 DOI: https://doi.org/10.17925/OPHT.2021.15.1.2
Primary myopia is a refraction anomaly of a non-accommodated eye with a spherical equivalent of -0.5 dioptres (D) or lower, often caused by an elongation of the visual axis.1 While visual axis length often varies between individuals and populations, a ‘long eye’ is often defined by an axial length greater than 24.5 mm.2 The aberrant anatomy of […]
What New Lens Technologies Are on the Horizon?
touchREVIEWS in Ophthalmology. 2021;15(1):6–8. DOI: https://doi.org/10.17925/OPHT.2021.15.1.6
Cataract surgery has undergone a significant transformation in the last 70 years, becoming a safer and more reliable treatment with better visual outcomes. An important part of this transformation has been the advent of new intraocular lens (IOL) technologies, starting with the first IOL made of polymethyl methacrylate and implanted by Sir Harold Ridley in […]

Antibiotic Stewardship in Ophthalmic Clinical Practice
Since the introduction of antibiotics, bacterial resistance has continued to pose an ongoing problem across all infectious diseases,1 and ocular infection pathogens are no exception. Antibiotic resistance in ophthalmology has become an important global health issue. A total of 4.5 million cataract surgeries are performed each year.2 These carry a risk of postoperative infection, particularly endophthalmitis, a severe sight-threatening inflammation of the eye.3,4 As a result, a number of common antibiotics are prescribed to prevent infections.5 Since up to 97% of ophthalmologists use post-operative antibiotics, this is equivalent to 61 million days per year of antibiotic exposure.6 Antibiotics are also used in the treatment of common ophthalmic infections such as acute infective conjunctivitis, which is one of the most common issues encountered in primary care and constitutes a significant healthcare burden.7 Antimicrobial resistance, which develops naturally through gene mutations, has been identified as a major healthcare threat worldwide, largely due to overuse and misuse of antibiotics. The presence of antibiotic resistance among ocular pathogens is a major concern, as it complicates the choice of antibiotic and may lead to treatment failure.8 The need for responsible use of antibiotics is increasingly recognised, and in recent years, the concept of antimicrobial stewardship has developed. Antibiotic stewardship has been defined in a consensus statement from the Infectious Diseases Society of America, the Society for Healthcare Epidemiology of America, and the Pediatric Infectious Diseases Society as ‘coordinated interventions designed to improve and measure the appropriate use of [antibiotic] agents by promoting the selection of the optimal [antibiotic] drug regimen including dosing, duration of therapy, and route of administration’.9 Santen have recently launched the Re-SOLVE Antibiotic Resistance initiative, which aims to promote antibiotic stewardship by recommending a set of actions which encourage the sustainable and effective use of antibiotics, including selection of an antibiotic therapy.10 In an expert interview, Mr Ali Mearza describes the aims of the RE-SOLVE initiative. Q. Could you tell us a little about the aims of the Re-SOLVE antibiotic initiative? The campaign launched in October 2020 and was dedicated to the importance and benefits of sustainable antibiotic use in ophthalmology.10 The Re-SOLVE campaign aims to rapidly and responsibly raise awareness of the threat of antibiotic resistance in ophthalmology; catalyse an environment of urgent action and antibiotic stewardship in the ophthalmology community; and promote awareness of, and access to, medical education opportunities and networks of helpful experts. Q. What practical advice would you give to ophthalmologists in terms of the use of prophylactic antibiotics during and after cataract surgery, and infectious complications such as endophthalmitis? During cataract surgery, there is now good evidence to support the use of povidone-iodine in the conjunctival sac prior to the commencement of surgery, followed by intracameral antibiotic (either cefuroxime or moxifloxacin) at the end of surgery.11,12 This has been showed to lower the incidence of endophthalmitis significantly. Following surgery, a short course of antibiotic x4/day for a week, makes more sense rather than a prolonged 4-week course as is the case still in many centres. Q. What is the importance of selecting a therapy with short duration to minimise antibiotic use in everyday practice? Short-term therapy (1 week) may be enough post-operatively as an additional measure above using povidone-iodine and intracameral antibiotics during cataract surgery. Additionally, no tapering – these two factors could positively impact the lowering antibiotic exposure and slow down the development of antibiotic resistance. Q. How else can ophthalmologists select antibiotic therapies that will minimise antibiotic use in everyday practice? It is important that, where possible, the most appropriate antibiotic is selected and used for the shortest duration of time possible. Most departments work closely with their microbiology colleagues to develop guidelines on the most appropriate use of antibiotics and these should be reviewed yearly in line with changes in antibiotic resistance. Antibiotics should not be used where not indicated, and ongoing training and education will help instil the message of appropriate use for the next generation of ophthalmologists.
