Modern ophthalmology faces a critical challenge: the need to implement sustainable practices and minimize the ecological footprint of our field. Given the high environmental impact associated with ophthalmic practices, it is time for eye surgeons around the world to take action.

The World Health Organization has identified climate change as the greatest health threat of our time. Globally, the healthcare sector contributes to approximately 5% of all greenhouse gas emissions, with this figure rising to 10% in the United States. A significant part of this impact comes from the high waste production and emissions related to single-use ophthalmic devices and equipment used in surgeries. For instance, a single cataract surgery in the UK can generate up to 130 kg CO₂ equivalents, which is comparable to driving a car for 310 miles B11 B12.
Ophthalmology generates a staggering amount of waste daily. A typical cataract surgery in the US uses single-use eyedrops, phaco tips, tubing, gowns, and other accessories, resulting in vast amounts of packaging and clinical waste. This is driven by a prevalent "single-use mindset" in many developed countries B13B14.
Successful models like the Aravind Eye Care System in India demonstrate that sustainability and patient safety can coexist. By using reusable materials and efficient sterilization processes, Aravind has reduced the CO₂ output per cataract surgery to about 6 kg, without compromising safety standards B12.
To reduce environmental impact, ophthalmologists should adhere to the principles of the 5 R's: Reduce, Reuse, Recycle, Rethink, and Research. Practical measures include:
Oertli commits with several initiatives such as innovative water treatment systems, solar energy investments, eco-friendly packaging, and local sourcing to reduce waste and carbon emissions.
The primary objective of the Lean Factory is to increase the efficiency of work processes and production volumes to achieve set growth targets. With an investment of around 30 million Swiss francs, this new building underlines the commitment to a sustainable future and the clear commitment to Switzerland as the only production location.
These initiatives highlight Oertli’s commitment to sustainability across various aspects of its operations, from energy use and waste management to local sourcing and digitalization, ensuring a greener future for ophthalmic devices like phaco systems, vitrectomy machines, and surgical instruments, while supporting ophthalmologists worldwide.
It is evident that ophthalmology significantly contributes to environmental degradation. As stake holders in eye surgery, we have a duty to protect not only our patients but also our planet. It is time to reassess our practices and make sustainability a core component of ophthalmic care. The future of our patients and our earth depends on it B1.
