COMT IJCAHPO Ophthalmic Certifications License: Complete Roadmap
Follow this path to organize your licensing and exam preparation
Phase 1: Ocular Motility, Refraction and Lensometry (22% of the exam)You are here
Drill versions and ductions, cover testing with prisms, Worth 4-Dot, Maddox rod and Krimsky, then retinoscopy, refinement, transposition, vertex conversion and manual lensometry — the three heaviest clinical skill areas on the COMT blueprint.
Phase 2: Imaging, Photography and Supplemental Testing (23% of the exam)
Work through fluorescein and ICG angiography phases, corneal topography, OCT and scanning laser testing, fundus, slit lamp and external photography, plus glare, PAM, colour vision, tear tests and electrophysiology identification.
Phase 3: Contact Lenses, Biometry and Anterior Segment Measurement (12% of the exam)
Fit and evaluate rigid, toric, bifocal, scleral and bandage lenses, then master standardised A-scan and B-scan echography, keratometry, pachymetry and anterior chamber depth assessment.
Phase 4: Patient Services, Pharmacology, Surgical Assisting and General Medical Knowledge (23% of the exam)
Review ophthalmic patient education and emergency first aid, ocular pharmacology by drug class, aseptic technique and laser safety, ocular anatomy and systemic disease, ethics and coding, then finish the practice bank.

Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
What's Next After the COMT?
After passing the COMT, you can pursue these career paths
OSA
Add the IJCAHPO Ophthalmic Surgical Assisting credential to formalise sterile first-assistant work in cataract, vitreoretinal and oculoplastic theatres.
ROUB
Add the Registered Ophthalmic Ultrasound Biometrist credential to specialise in standardised A-scan biometry and IOL power measurement.
CDOS
Add the Certified Diagnostic Ophthalmic Sonographer credential to specialise in diagnostic B-scan and ultrasound biomicroscopy of ocular and orbital pathology.
