In this video from the 40th Congress of ESCRS in 2022 in Milan, David Chang, MD, delivers a keynote lecture titled “Reducing Cost and Environmental Impact of our Highest Volume Procedure.” He discusses why we should care about cataract surgery’s carbon footprint - with guidance from the WHO, the Lancet, the Royal College of Surgeons, and other organizations. He mentions literature from the Aravind Eye Hospital, which has an astoundingly low endophthalmitis rate and carbon footprint of cataract surgery and compares these to statistics in the United States. He also describes a recent survey of cataract surgeons’ and nurses’ attitudes toward ophthalmology operating room waste, which demonstrates that 95% of individuals feel that the status quo is not adequate from an environmental and economic sense. He also mentions the impact of realities like general surgery’s rules being applied to ophthalmology and items like lengthy manufacturer instructions for use manuals increasing the size and weight of intraocular lens packaging. The talk also contains a tour of the EyeSustain website.
Whether you operate at an ambulatory surgery center (ASC) or a hospital outpatient department (HOPD), have your surgical facility or department take the EyeSustain Pledge, which applies only to ophthalmic surgical cases. The pledge should be filled out by one designated representative per facility (e.g., administrator, nursing or medical director, head ophthalmic nurse, or head of the ophthalmology department). Be the ophthalmologist or nurse who champions sustainability to your operating room leadership and becomes the catalyst for change.
We agree to promote sustainability of quality eye surgery through education and collaboration. To reduce unnecessary ophthalmic surgical waste, we specifically pledge to:
The ophthalmic nursing and surgeon staff can watch Dr. Chang’s 15-minute video presentation at “Introducing EyeSustain”. Along with his 2023 JCRS editorial, this video discusses the impact of, and ways to reduce ophthalmic surgical waste. It also provides a quick tour of the EyeSustain website.
Surveys on North American and European ophthalmologists’ and ophthalmic nurses’ attitudes regarding surgical waste can be downloaded and distributed.
Consider appointing a sustainability leader for ophthalmic ORs (e.g., MD or RN leader)
Many standardized packs contain items that are frequently not used, and which could be separately opened when needed.
Surgeons should consult and collaborate with the nursing staff to update their custom packs on a regular basis.
Consider performing a 2-week challenge, by tracking which items in surgical packs go consistently unused over a 2-week interval. Surgeons can then evaluate whether these unused items can be packaged separately and opened only when necessary.
Needless waste of ophthalmic surgical topical medication has a significant financial and environmental impact.
Four major American societies have endorsed and released a 2022 position statement supporting the use of multidose bottles of ophthalmic drugs on multiple patients until the bottle expiration date.
The statement also encourages allowing patients to take home a bottle of partially used medication, if appropriate, that was specifically opened for them.
Supporting resources and information are available in a section on reducing surgical drug waste on the EyeSustain website.
In two surveys of ophthalmologists 47% of European surgeons and 44% of North American surgeons had eliminated full body draping (using only a face drape). Another 41% (European) or 51% (North American) would consider eliminating the full body drape.
50% of European surgeons and 56% of North American surgeons did not have patients change into gowns (wearing their own clothing instead). Another 27% (European) or 34% (North American) were willing to eliminate having patients change into hospital gowns for cataract surgery.
A registry-based retrospective study published in the BJO found no difference in endophthalmitis rates when patients were changed into hospital gowns, compared to wearing their own clothing into the operating room.
In many regions, large plastic eye drapes may be backordered, so this transition may take time to implement.
In both the ESCRS and North American surveys, 8-10 times as many surgeons preferred reusable instruments over disposable instruments of equal cost.
Examples of reusable options include reusable metal or diamond blades, reusable phaco tips, etc.
Alcohol-based surgical scrub is recommended for presurgical antisepsis by leading health organizations. One study modeled significant savings in cost, water, and scrub time by converting from water-based to waterless scrub techniques for ophthalmic surgery.
