Measure corneal curvature with keratometers or ophthalmometers to aid in the diagnosis of conditions, such as astigmatism.

“Measure corneal curvature with keratometers or ophthalmometers to aid in the diagnosis of conditions, such as astigmatism.” is a core task performed by Ophthalmic Medical Technicians. Among the occupation's 20 rated tasks, workers place it 11th by importance (#10 most important). About 95% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E2. Exposure with tools — software built on top of a language model (not the model alone) could cut the time by at least half.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.50. Automation potential label: T1.
