Learning
Memory Aids
Mnemonic
Think: IRIS + -OTOMY (cutting). A 'cut in the iris'. 'Irid-' like 'iridescent' (related to the iris), '-otomy' like 'tracheotomy' (a surgical cut).
Conceptual Metaphor
Often conceptualised as 'drilling a drainage hole' or 'creating a safety valve' in the eye's internal structure.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'иридэктомия' (iridectomy), which implies tissue removal. 'Иридотомия' is the correct, direct equivalent.
- Avoid literal decomposition like 'радужка' + 'разрез', as the established medical term is 'иридотомия'.
Common Mistakes
- Misspelling as 'iridotomy' (missing 'i'), 'irridotomy' (double 'r'), or 'iridotamy'.
- Confusing it with 'iridoplasty' (reshaping) or 'trabeculoplasty' (a different glaucoma laser surgery).

FAQ
Frequently Asked Questions
The procedure is typically performed with topical anaesthetic drops and is described as causing minimal discomfort, often just a brief sensation of pressure or a tiny flash of light.
An iridotomy is a cut or hole made in the iris, while an iridectomy involves cutting out and removing a small full-thickness piece of iris tissue.
Visual recovery is usually very quick, often within hours, though some blurriness or mild irritation may persist for a day or two. Full stabilisation of intraocular pressure takes a few weeks.
The opening created is typically permanent, but in some cases, especially with certain laser types, it can close over time and require a repeat procedure.
