Cataract surgery is usually possible with heart disease, as it is a short, low‑stress procedure under local anaesthetic, but medical clearance may be needed.
When surgery is generally safe
Most stable cardiac patients can proceed.
- Well‑controlled angina, heart failure, or arrhythmias
- Recent cardiac review confirming fitness for minor procedures
- Use of topical or sub‑Tenon’s anaesthesia rather than full general anaesthetic
- Monitoring of blood pressure and heart rate during surgery
- Possibility of performing surgery in a hospital setting with cardiac support if needed
When timing may need adjustment
Some situations call for delay or special planning.
- Recent heart attack, stent, or cardiac surgery awaiting stabilisation
- Unstable angina or decompensated heart failure
- Need to coordinate with cardiology about antiplatelet or anticoagulant therapy
- Considering sedation carefully in patients with limited cardiac reserve
- Balancing visual benefits against overall medical risk in frail individuals
