Age-related macular degeneration (AMD) is the leading cause of blindness in the developing world. AMD causes a substantial burden on patients, reducing independence, their ability to conduct daily activities, and increasing rates of cognitive decline and depression. There is a significant unmet need for patients with AMD, which will grow as the population ages and rates of disease increase. In the past, many studies have demonstrated a benefit when coexisting cataract formation is treated by removing the cloudy lens. AMD-lenses are intraocular implants designed to improve visual acuity in patients with AMD, avoiding the need for cumbersome manual vision aids and magnifiers. Many IOLs have been investigated in AMD, with differing mechanisms aimed at overcoming visual impairment. Most AMD studies use Early Treatment Diabetic Retinopathy Study (ETDRS) chart-based assessments of vision, but BCVA does not correlate with lesion size or pattern, especially in geographic atrophy, and may not be the most appropriate measure to effectively assess vision defects in AMD before or after a cataract surgery. One option is a simple functional assessment of vision related to activities of daily living (ADL), based on a reproducible, task-based questionnaire. The test consists of 6 assessments of ADL to be completed by patients before and after cataract surgery. Experiences highlight the importance of including an assessment of ADL in patients receiving an implant, which gives an effective measure of patient satisfaction. We would welcome the use of similar questionnaires in larger studies of patients, to validate its utility in a broader patient population. In this review article, we (Scandinavian-Austrian-cooperation) summarize lenses designed for implantation in patients with AMD, and how best to improve outcomes through proper patient selection, appropriate vision evaluation using quality-of-life related assessment, and pre- and post-operative care.
