Certified Ophthalmic Assistant (COA) The COA exam puts your clinical precision under scrutiny? you’ll face questions on tonometry techniques, visual field interpretation, and patient positioning that mirror real exam-room scenarios. Mastery of A-scan biometry and slit-lamp procedures separates passing scores from those who stumble. Success demands accuracy in every procedural detail, not just textbook knowledge of ophthalmic care.
