Here is a true story of a decision made by the patient and his opthalmologist to allow a terminally ill patient who is expected to die soon and who has cataracts in both eyes to have cataract surgery to be able to see his family before he dies. The story is described at the National Public Radio websitehttps://www.npr.org/sections/health-shots/2017/12/03/565683105/should-eye-surgeons-fulfill-a-dying-mans-wish-to-see-his-family Should this decision be subjected to debate as an ethical issue? For example, the opthalmologist involved, who wrote the article, stated:Our anesthesiologist and others on the operating roo...

Various intraocular lens (IOL) designs have been developed to achieve better unaided vision for patients undergoing cataract surgery. Today's standard monofocal IOLs provide excellent distance visual acuity,1 whereas toric and aspheric IOLs optimize the refractive outcome.2,3 Bifocal IOLs provide uncorrected far and near visual acuity, whereas recently introduced trifocal designs flatten out defocus curves and thus additionally grant uncorrected intermediate visual acuity.4,5 To fully exploit the optical capabilities of these IOLs, especially bifocal and trifocal lenses, some requirements need

Purpose of review To describe recent evidence regarding methods of evaluation of retinal structure and function prior to cataract surgery. Recent findings Studies in patients with cataract but no clinically detectable retinal disease have shown that routine use of optical coherence tomography (OCT) prior to cataract surgery can detect subtle macular disease, which may alter the course of treatment or lead to modification of consent. The routine use of OCT has been especially useful in patients being considered for advanced-technology intraocular lenses (IOLs) as subtle macular disease can be a contraindication to the ...

Purpose of review To evaluate and summarize literature from the past 18 months reporting advancements and issues in astigmatism assessment prior to cataract surgery. Recent findings New and updated toric calculators and regression formulas offer the opportunity for more accurate lens selection for our patients. Concurrently, improvements in topographic evaluation of corneal keratometry have allowed for a decrease in unplanned residual corneal astigmatism. Measuring posterior corneal astigmatism is especially valuable in eyes with keratoconus when planning to implant toric intraocular lens (IOL) and now allows access t...

Purpose of review Achieving secure wound closure in clear corneal incision cataract surgery remains highly desired for its role in reducing infection risk and leak-related complications, including hypotony, corneal edema, and lens dislocation. Although classic techniques of stromal hydration or wound suturing represent traditional approaches, the introduction of newer and more effective ocular surface adhesives has increased the options that are available. This review aims to provide an update on the peer-reviewed literature regarding wound closure and the currently available and investigational tissue adhesives used to ...

Purpose of review Povidone–iodine (PVI) is a disinfectant and antiseptic agent used for preoperative preparation of the skin and mucous membranes, as well as for the treatment of contaminated wounds. Currently regimens for prophylaxis against postsurgical endophthalmitis are being modified, including a total withdrawal of antibiotics in intravitreal injections. The aim of this study was to evaluate the use of PVI in ophthalmology. Recent findings As a result of its broad spectrum of microbicidal activity, PVI is routinely used in ophthalmic surgery. However, various protocols are applied worldwide and within dif...

Purpose of review There is continuing debate regarding the safety, efficacy, and necessity of intracameral antibiotics to prevent postoperative endophthalmitis. We summarize the most recent evidence-based publications that either support or caution against this practice. Recent findings Several additional large, international retrospective clinical studies found a significant reduction in endophthalmitis rates with intracameral antibiotic prophylaxis. Many surgeons are looking for alternatives to vancomycin for intracameral prophylaxis because of its association with the rare but sight-threatening complication of hemo...

Purpose of review To highlight the existing and emerging cataract surgery trends in patients with insufficient mydriasis. Discuss the latest pharmacological approaches for pre and intraoperative pupil dilatation. Present the variety of newest pupil expansion devices; critically review their advantages and possible limitations to be considered by the surgeon. Recent findings The intracameral use of various mydriatic combinations augmenting the preoperative mydriatic instillations is currently gaining popularity in cataract surgery. Two main options are available: bolus injection of pharmacological agent or its constant...

Purpose of review Although cataract surgery can effectively restore visual function in many patients with cataract, PCME remains an important cause of suboptimal visual acuity. The present review provides an overview of the current literature on the prevention and treatment of PCME. Recent findings Optimal prevention of PCME starts preoperatively with a personalized risk assessment. Diabetes mellitus, retinal vein occlusion, epiretinal membrane, macular hole, and uveitis are the most important risk factors for developing cystoid macular edema after cataract surgery. Topical NSAIDs either in addition to, or instead of,...
