5 syllables: ker, a, to, me, try. Stress on to.
ker-uh-TOH-muh-tree
/ˌkɛɹ.əˈtoʊ.mə.tri/
keratometry is pronounced ker-uh-TOH-muh-tree (/ˌkɛɹ.əˈtoʊ.mə.tri/). It has five syllables (ker-a-to-me-try), with the stress on "to". Keratometry is the scientific measurement of the cornea’s curvature, typically used to assess astigmatism and fit contact lenses. It involves precise optical readings to determine diopters and curvature radii, guiding corrective strategies. In clinical use, it provides essential keratometric values for diagnosing eye conditions and planning refractive procedures.

"The ophthalmologist performed keratometry to evaluate the patient’s corneal curvature before selecting toric lenses."
"During the preoperative assessment, keratometry helped determine the appropriate lens power for the patient’s contact lens fitting."
"Advanced keratometry can track corneal changes over time after refractive surgery."
Pronounce as KEH-ruh-TOM-uh-mee-tree. Primary stress on the third syllable (ˌkɛrəˈtɒmɪtri). Break it into ke-ra-to-me-try with clear enunciation of -tɒ- and -mɪ-; the final -try has a light y sound. IPA: US /ˌkɛrəˈtɒmɪtri/, UK /ˌkɛrəˈtɒmɪtri/, AU /ˌkɛrəˈtɒmɪtri/. For ease, think “ker-uh-TOH-muh-tree,” but keep the second syllable unstressed and crisp.
Common errors: over-stressing the second syllable (ker-A-to-me-try); mispronouncing the first vowel as a long ‘ee’ (kee-RAH-toh-muh-try); softening the ‘t’ into a flap in rapid speech. Fix by practicing the sequence ke-rah-TOM-uh-mee-tree with a 2-2-3 beat, ensuring the third syllable carries the stress and the -tr- cluster is crisp.
US and UK share /ˌkɛrəˈtɒmɪtri/; slight vowel length differences exist in non-stressed vowels, and rhoticity in US makes /ɹ/ clearer in the initial syllable. Australian tends toward non-rhotic influences in rapid speech, but in technical terms the pronunciation remains close to /ˌkɛrəˈtɒmɪtri/ with slightly shorter final syllable vowels. Overall, core stress pattern remains the same.
The difficulty lies in the multi-syllabic structure and the mid-word relocation of stress to the third syllable, plus the consonant cluster -tr- in the middle and the final -try. You’ll hear and feel a quick, light -ə- between strong consonants. Practice by chunking ke-ra-to-me-try, then gradually speed up while maintaining crisp /t/ and clear final /i/ sound.
A key peculiarity is the subtleties of the -tɒ- sequence in non-American pronunciations, where the /ɒ/ can sound more open or rounded depending on speaker. Additionally, the trailing -metry ending mirrors other -metry terms and tends to be a non-syllabic or lightly pronounced -try in fast clinical speech. Keeping the stress on the 3rd syllable helps avoid common misplaces of emphasis.

Keratometry derives from the Greek keratos meaning ‘horn’ or ‘cornea’ (from kerat-, kerato- meaning cornea) and metry from med. measurement. The term surfaces in medical usage in the late 19th to early 20th century as ophthalmology formalized quantification of corneal curvature. Kerato- is an combining form indicating relation to the cornea, used across multiple ophthalmic terms, while -metry denotes measurement. The sense evolved from basic curvature assessment to a precise optical measurement technique integral to refractive care. First known uses appear in ophthalmic literature of the late 1800s, with growth in instrument-based measurement through keratometers and later automated topographers. The compound literally means “measurement of corneal curvature.”
