Aspirin Management Before Cataract Extraction
Aspirin should NOT be discontinued before cataract surgery—continue it throughout the perioperative period. 1, 2
Evidence-Based Recommendation
The most recent and highest quality evidence demonstrates that aspirin continuation is safe for cataract surgery:
A 2025 systematic review and meta-analysis of 65,196 patients found that aspirin continuation increases only subconjunctival hemorrhage risk (RR: 1.74), but does NOT increase sight-threatening complications including hyphema, retrobulbar hemorrhage, vitreous hemorrhage, or visual acuity changes. 2
The American College of Chest Physicians explicitly recommends continuing aspirin for minor procedures including cataract surgery, regardless of cardiovascular risk. 1
The 2014 ACC/AHA perioperative guidelines specifically note that "in some instances in which there is minimal to no risk of bleeding, such as cataract surgery," anticoagulation considerations are minimal. 3
Clinical Rationale
Why Continuation is Preferred
Thrombotic risk outweighs bleeding risk: Discontinuing aspirin in patients with cardiovascular disease increases the absolute risk of stroke or cardiovascular events by approximately 2% within 30 days. 4
Modern surgical techniques minimize bleeding: Clear corneal phacoemulsification is particularly advantageous in patients on antiplatelet therapy, with no significant intraoperative bleeding complications. 5
Real-world safety data: A 2023 study of patients with long-term aspirin use after percutaneous coronary intervention showed no statistically significant difference in bleeding complications during cataract surgery compared to patients not taking aspirin. 6
Specific Patient Populations
For patients with coronary stents:
- Continue aspirin throughout the perioperative period without interruption 1, 4
- If on dual antiplatelet therapy (aspirin + P2Y12 inhibitor), continue both agents as cataract surgery poses minimal bleeding risk 1
For patients on aspirin for secondary cardiovascular prevention:
For patients on aspirin for primary prevention only:
- Can continue aspirin as bleeding risk remains minimal for cataract surgery 1
Common Pitfalls to Avoid
Do NOT use the outdated 7-10 day discontinuation window that was previously recommended—this unnecessarily prolongs thrombotic risk without meaningful bleeding reduction. 1, 5
Do NOT discontinue aspirin in patients with recent coronary stents (within 6-12 months for drug-eluting stents, within 4-6 weeks for bare-metal stents), as stent thrombosis risk is catastrophic. 7
Do NOT substitute aspirin with heparin bridging—anticoagulants do not protect against stent thrombosis and actually increase bleeding risk. 7
Practical Summary
Hold time: 0 days (do not discontinue)
The overwhelming consensus from current guidelines and high-quality evidence supports aspirin continuation for cataract surgery. The only bleeding complication with increased risk—subconjunctival hemorrhage—is cosmetic and self-limited, while the thrombotic risks of discontinuation can be life-threatening. 1, 5, 2, 6
