Certified Ophthalmic Assistant Practice Exam

Question: 1 / 400

What best determines the dioptric power of the cornea?

Agar

Impact-resistance level

Keratometer readings

The dioptric power of the cornea is best determined by keratometer readings. A keratometer is an ophthalmic instrument used to measure the curvature of the cornea, which helps in determining the dioptric power of the cornea. This measurement is important in assessing refractive errors like astigmatism and in fitting contact lenses.

Options A, B, and D are not correct because they do not pertain to the measurement of the dioptric power of the cornea. Agar is a substance used in microbiology, impact-resistance level relates to the durability of eyewear, and universal precautions refer to infection control practices in healthcare settings. These options are not relevant to determining the dioptric power of the cornea.
