Under the supervision from an optometrist, the CPOT™ may perform technical duties such as taking detailed patient histories, measuring visual acuity, measuring the curvature of the cornea (Keratometry), glaucoma screening, blood pressure testing, and measuring the distance between the pupils of the eye. In addition, they may well order prescription eyewear, modify contact lenses, explain contact lens care regimens, photographing the interior of the eye, supervise staff, and other duties that optometrist may delegate.
Eligible applicants must have earned the CPOA™ title, hold a current CPOA™ designation, and verify a minimum of six months additional employment in the eye care field as a CPOA™. Some candidates may sit directly for the CPOT™ examination by having met the other education criteria. Contact the CPC office for information.
The CPOT™ examination consists of two parts – a written and a practical examination. The CPOT™ written examination consists of 225 multiple choice questions related to pre-testing procedures, clinical procedures, ophthalmic optics and dispensing, refractive status of the eye and binocularity, procedures, ophthalmic optics and dispensing, refractive status of the eye and binocularity, anatomy and physiology, and practice management.
The CPOT™ practical examination is a hands-on demonstration of specific skills required and candidates must demonstrate their abilities at three testing stations: 1) case history/pre-testing; 2) Blood Pressure/Contact Lenses/Tonometry/Pachymetry/Simulated Dilation; 3) Lensometry/Base Curve/Pupillary Distance. See practical candidate handbook for detailed information.
The following outline includes a brief explanation of the areas covered on the CPOTTM examination (refer to the CPOTTM Handbook for Candidates for the full outline).
Pre-Testing Procedures (20%) – Case history, visual acuity, vision screening and preliminary testing techniques, color vision, and stereo acuity.
Clinical Procedures (28%) – Corneal Topography/Automated Keratometry, tonometry, visual fields, sphygmomanometry, contact lenses, vision therapy, triage and first aid, vision rehabilitation, and special ocular procedures.
Ophthalmic Optics and Dispensing (18%) – Optical principles of light, prescriptions, lenses, frame selection, and adjustment.
Refractive Status of the Eye and Binocularity (12%) – Refractive errors, refractive conditions, eye movements, binocular vision.
Anatomy and Physiology (15%) – General anatomy and physiology, eye anatomy, and pharmacology.
Practice Management (7%) – Office management, professional issues, government rules and regulations, and health information technology.
