Depending on their scope of practice, some are sharp enough to interpret diagnostic data. Certification does not just stop after their educational program, some at a university level, but can be further pursued with continuing education.
Diagnosis and assesment plan are a different story. but it's interesting to notice the similarities rather than the MAIN difference. Common diseases like cataracts, glaucoma, and AMD are widely understood with the technicians I work with. (When I say common, I'm not emcompassing the odd-ball manifestations xD)
My coworker is planning to take the ophthalmic technician test soon. She is very intelligent and knows the clinical aspect of the job well. Surprisely, it's very similar to the price of the OAT 🙂
