So Many Injections, So Much Waste: Understanding the Environmental Impact of Intravitreal Injections

Purpose: To understand the environmental burden associated with intravitreal (IVT) injections and propose actionable solutions to mitigate this impact. Methods: An analysis of current IVT injection practices was conducted, focusing on packaging waste, energy consumption, the carbon footprint, and disposal processes. Data on the environmental footprint of IVT injections were collected from the literature and industry reports. Sustainable practices were evaluated for their feasibility and impact on reducing waste and emissions. Industry efforts to address these environmental concerns were also surveyed. Results: This study found that the packaging of IVT injection medications, especially brand-name drugs, generates considerable waste. In addition, transportation and storage of these medications substantially contribute to carbon emissions. Implementing take-back programs, reducing packaging size, and using reusable or biodegradable coolers could significantly decrease waste. Adopting multidose packaging and streamlining injection practices can reduce both waste and costs. Sustainable practices have the potential for considerable environmental and economic benefits without compromising patient care. Conclusions: Addressing the environmental burden of IVT injections requires a multifaceted approach involving many different parties. Collaboration among retina specialists, industry partners, and stakeholders is essential to foster sustainable practices, reduce waste, and minimize carbon emissions. This effort will ensure that our commitment to patient care matches our commitment to environmental stewardship.
