Perspective Retinal Imaging The Role of Ultra-widefield Retinal Imaging as a Standard Assessment Tool in the Cataract Practice Kerry K Assil 1 and V Nicholas Batra 2 1. Assil Eye Institute, Beverly Hills, California, US; 2. Batra Vision, San Leandro, California, US C omprehensive evaluation of retinal health prior to and following cataract surgery is critical to supporting optimal outcomes. In addition to the importance of identifying retinal pathology that may prevent or delay cataract surgery, continuous advances in refractive intraocular lens technology and cataract surgical technique, coupled with increasingly high expectations regarding visual outcomes among younger patients, make the consideration of long-term quality of vision paramount in the cataract assessment. Optos ® ultra- widefield retinal imaging supports this clinical objective by providing imaging standardization in a streamlined, patient-friendly exam process, supporting robust documentation that facilitates mapping of disease progression, and offering potential economic advantages in a resource- constrained environment.

TOU CH MED ICA L MEDIA Due in part to continuous improvement in the safety, speed, and refractive outcomes of cataract surgery, the number of cataract procedures has increased steadily over the past 30 years, and the percentage of patients undergoing the procedure at a younger age is also increasing. These trends were documented in a frequently cited population-based study of Omsted County, Minnesota, that compared rates of cataract surgery between 2005 and 2011 to those in the prior 25 years. Data on more than 8,000 cataract procedures in the most recent period revealed that the incidence of cataract surgery had increased significantly, the interval between first and second eye surgery narrowed significantly, and 19% of patients elected cataract surgery before age 65. 1 This rise in cataract surgery rates will continue to accelerate as the US population ages; the number of Americans over age 65 is expected to nearly double by 2050, to 83.7 million. 2 Along with the increasing volume driven by this large demographic wave, there are a number of important implications of the shift to earlier cataract surgery and the increasing use of sophisticated premium intraocular lens (IOL) technologies. Perhaps the most significant of these is that many patients will live for decades after the procedure. These patients have high expectations of their immediate postoperative visual outcomes and also expect to continue to see well as they age. With sustained quality of vision the main therapeutic objective, it has become paramount to perform thorough retinal exams pre-surgically and postoperatively to identify pre-existing retinal disease that might prevent, delay, or alter surgery, to anticipate future retinal problems—particularly to the degree that this prospect may affect lens choice—and to provide an initial, post-cataract baseline for monitoring future pathological changes. In this review, we will describe the integration into our pre- and post-cataract surgery assessments of a specific imaging technology that has shown utility in retinal disease detection and management for both the general ophthalmologist and the retinal specialist. In our experience, ultra-widefield (UWF™) retinal imaging (Optos plc., Dunfermline, Scotland) and the clinical and practical value of the high-resolution, digital optomap ® images they produce, have complemented the information available to us from standard approaches, including conventional fundus examination and optical coherence tomography (OCT), thereby improving our ability to rapidly and accurately identify retinal pathology, facilitating consultation with retina colleagues, and resulting in enhanced patient care, increased patient satisfaction, and greater efficiency within our practices. As a result, Optos ® UWF retinal imaging has become a routine component of perioperative evaluation in our cataract cases, based on the unique advantages of the technology, and we believe that other cataract practices may benefit from considering this approach. 31
