# Is cataract surgery suitable if you take warfarin or DOACs?

Cataract surgery is often safely performed while patients remain on warfarin or direct oral anticoagulants (DOACs), with individualised planning.

## General approach

The goal is to avoid clotting events while minimising surgical bleeding.

- Checking recent INR for warfarin users to ensure it is within the target range
- Continuing DOACs at usual doses in many routine cases
- Preferring topical or sub‑Tenon's anaesthesia to avoid needle injections near the eye
- Monitoring for minor subconjunctival bleeding, which usually settles without issue
- Coordinating with prescribing doctors for high‑risk cardiovascular patients

## When regimen adjustments may be needed

Some situations justify dose timing or temporary changes.

- Very high INR or a history of significant bleeding
- Complex ocular surgery or combined procedures with greater bleeding risk
- Renal impairment affecting DOAC clearance
- Advice to delay or skip one dose before surgery in selected patients
- Documented plan for restarting full anticoagulation after the operation
