Reducing ophthalmic surgical waste through electronic instructions for use: a multisociety position paper.

Every ophthalmic surgical supply, including intraocular lenses (IOLs), IOL cartridges, and ophthalmic viscosurgical device syringes, is packaged with instructions for use (IFU). These pamphlets are printed in multiple languages and, in the case of an IOL, significantly increase the size and weight of the packaging. To eliminate this significant and unnecessary source of waste, we recommend that manufacturers move to Quick Response codes that link to online electronic IFU (e-IFU) as a sensible alternative. In addition to reducing carbon emissions and manufacturing costs, e-IFU can be updated more easily and accessed by surgeons in the clinic, where IOL models and powers are selected. Varying and inconsistent IFU requirements between different countries are a barrier to wider adoption of e-IFU by the ophthalmic surgical industry. Regulatory agencies in every country should allow and encourage e-IFU. This position paper has been endorsed by the 3 major societies that sponsor EyeSustain, a consortium of global societies dedicated to advancing sustainability in ophthalmology.

Therapeutic visual rehabilitation in a patient with high hyperopia and flat cornea years after radial keratotomy.

A 51-year-old man was referred for refractive surgery evaluation. Spectacle dependence and poor visual quality in both eyes was his chief complaint. He cannot tolerate contact lenses. Corrected distance visual acuity (CDVA) was 20/40 in both eyes. Manifest refraction was +5.25 -2.25 @ 90 (20/40) in the right eye and +6.25 -2.25 @ 105 (20/40) in the left eye. The patient had a history of radial keratotomy (RK) almost 30 years ago in both eyes and at the slitlamp presented 8 RK incisions, proportionally spaced between one another. All incisions were closed, and there were no relevant signs of scarring. The patient denied any history of ocular trauma, systemic disease, or medications. Corneal topography with different technologies revealed an irregular pattern with marked central flattening in both eyes, with some points below 30 diopters (D) (Supplemental Figures 1 and 2, available at http://links.lww.com/JRS/A862 and http://links.lww.com/JRS/A863, respectively). There were no signs of cataract, and fundus examination was normal. Optical coherence tomography (OCT) of the right eye revealed a more homogeneous thickness pattern, little variation between the thinnest and thickest areas, and adequate transparency (Figure 1JOURNAL/jcrs/04.03/02158034-202306000-00018/figure1/v/2023-05-31T172126Z/r/image-tiff). In the left eye, there is wide variability between the thinnest and thickest stromal points, with annular thinning and central thickening (Figure 2JOURNAL/jcrs/04.03/02158034-202306000-00018/figure2/v/2023-05-31T172126Z/r/image-tiff). Both eyes show marked epithelial irregularity. Considering this patient's current ocular status, how would you reach visual rehabilitation? Because he is contact lens intolerant, would you consider surface ablation, for example, photorefractive keratectomy (PRK) with mitomycin-C (MMC)? If that were the case, would you think of an optimized or a topography-guided (TG) treatment? Would you immediately consider a corneal transplant option? Would you instead consider a more conservative approach? Which one and why?

Intracameral antibiotics: Safety, efficacy, and preparation.

UNLABELLED: Endophthalmitis is a rare but potentially devastating complication of cataract surgery. This article presents an overview of endophthalmitis prophylaxis and the use of intracameral antibiotics. It highlights available intracameral antibiotics with respect to pharmacology, spectrum of activity, dosage and preparation, safety, and efficacy profiles, as well as toxic anterior segment syndrome risks to better define the potential use of these medications in the prevention of endophthalmitis. FINANCIAL DISCLOSURE: Proprietary or commercial disclosures are listed after the references.

Multifocal intraocular lenses: relative indications and contraindications for implantation.

UNLABELLED: This article presents an extensive overview of best clinical practice pertaining to selection and use of multifocal intraocular lenses (IOLs) currently available in the United States. Relevant preoperative diagnostic evaluations, patient selection criteria, counseling, and managing expectations are reviewed, as well as how to approach patients with underlying ocular intricacies or challenges and best practices for intraoperative challenges during planned implantation of a multifocal IOL. Managing the unhappy multifocal IOL patient if implantation has been performed is also addressed. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned.

Prevention, diagnosis, and management of acute postoperative bacterial endophthalmitis.

This distillation of the peer-reviewed scientific literature on infection after cataract surgery summarizes background material on epidemiology, etiology, and pathogenesis, describes the roles of surgical technique and antibiotic prophylaxis in prevention, and discusses diagnostic and therapeutic interventions in cases of suspected endophthalmitis.

Patient-centered care and refractive cataract surgery.

PURPOSE OF REVIEW: Cataract surgery has evolved significantly during the last few years. The introduction of aspheric, presbyopic correcting and toric intraocular lenses have shifted the emphasis of cataract surgery from just treating patients' functional symptoms to optimizing the refractive outcome of the procedure. RECENT FINDINGS: Studies emphasizing patient satisfaction and refractive visual outcomes have shifted the focus of cataract surgery to a more patient-centered approach. Refractive surgical technologies such as limbal relaxing incisions, laser-assisted in-situ keratomileusis, photorefractive keratectomy and conductive keratoplasty can be used in conjunction with traditional cataract surgical techniques. The wide array of intraocular lens choices has broadened the scope of refractive cataract surgery providing surgeons and patients with more options in determining refractive outcomes. SUMMARY: Cataract surgery has expanded into the realm of refractive surgery and there is a new emphasis on patient-centered care and an optimization of the refractive outcome of the procedure. This trend will continue as newer presbyopic correcting intraocular lenses become available.
