Which test can an assistant perform under the direct supervision of an optometrist?

Pachymetry is a test that measures the thickness of the cornea. In California, certain tests and procedures can be performed by assistants under the direct supervision of a licensed optometrist. This means that the optometrist must be physically present and responsible for the actions of the assistant while the procedure is being carried out.

Pachymetry is within the scope of what an optometric assistant can do under direct supervision, as it is a non-invasive procedure that supports the optometrist's diagnostics. The results can be used to assess conditions such as glaucoma and other corneal diseases, contributing valuable information for patient management.

In contrast, corneal surgery, prescription writing, and comprehensive eye exams require the professional judgment and expertise of a licensed optometrist. These activities involve more complex decision-making, potential risks to the patient, and legal implications that go beyond the scope of what an assistant can perform, even under supervision. Thus, pachymetry stands out as an appropriate option that aligns with the responsibilities designated to assistants in this setting.
