Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'iridotomia' (iridotomy).
- The '-ectomy' suffix is more specific than the general Russian 'операция' (surgery). It means 'surgical removal'.
- Do not confuse the 'iris' root with unrelated words like 'iron' or 'iridescent', despite phonetic similarity.
Common Mistakes
- Misspelling as 'iridectonomy' or 'iridechtomy'.
- Confusing with 'iridotomy' (a different procedure).
- Incorrect pronunciation stressing the first syllable (/ˈaɪ.rɪˌdek.tə.mi/). Correct stress is on 'dec'.

FAQ
Frequently Asked Questions
It is performed under local or general anaesthesia, so the patient does not feel pain during the procedure. Some discomfort may be felt during recovery.
An iridectomy involves surgically removing a full-thickness piece of the iris. An iridotomy (usually done with a laser) creates a small hole in the iris without removing tissue.
Initial healing takes a few weeks, but full visual stabilisation and recovery can take several months. Patients must use prescribed eye drops and avoid strenuous activity initially.
The procedure itself may slightly change the eye's refraction, potentially altering your glasses prescription. Your ophthalmologist will check your vision after full recovery.
