Key Responsibilities and Required Skills for Certified Ophthalmic Assistant (COA)

🎯 Role Definition

The Certified Ophthalmic Assistant (COA) is a certified clinical team member in ophthalmology clinics, hospitals, and surgical centers who performs standardized vision tests, diagnostic imaging (OCT, fundus photography), tonometry and pachymetry, assists providers during exams and minor procedures, prepares patients for surgery, documents encounters in the EHR, and educates patients on eye disease, medications, and post-operative care. The COA supports quality patient flow, maintains clinical equipment, follows infection control and compliance guidelines (HIPAA, OSHA), and serves as a first point of clinical contact to ensure safe, efficient, and compassionate eye care.

Core Responsibilities

Primary Functions

Perform standardized pre-examination testing including distance and near visual acuity (Snellen, ETDRS), pupils, color vision, and basic binocular function, documenting results accurately in the EHR to support diagnosis and treatment planning.
Administer and document non-invasive intraocular pressure (IOP) testing using Goldmann tonometry, Tonopen, or NCT (non-contact tonometry), following infection control protocols and calibration logs.
Conduct auto-refraction and manifest refraction assistance under provider direction, ensuring accurate refractive data for glasses, contacts, and surgical planning.
Operate and perform diagnostic imaging, including optical coherence tomography (OCT), fundus and anterior segment photography, corneal topography, and pachymetry, capturing high-quality images and uploading to PACS/EHR for interpretation.
Prepare patients for slit-lamp exams and surgical visits by instilling ophthalmic medications, performing dilation, and explaining expected sensations and post-dilation precautions while documenting medication lot numbers and times.
Assist ophthalmologists during office based procedures and minor in-office surgeries (e.g., intravitreal injections, minor lid procedures), maintaining sterile technique, passing instruments, and monitoring patient comfort.
Triage patient phone calls and walk-ins for urgent ocular complaints (red eye, sudden vision loss, pain) using clinical judgment and established protocols to escalate to the provider or emergency services when indicated.
Collect and document detailed ocular and systemic histories, allergies, current medications, prior surgeries, and family history relevant to eye disease to inform diagnostics and treatment.
Perform contact lens assessments and basic contact lens training/education, including insertion, removal techniques and troubleshooting for soft and specialty lenses per provider instructions.
Conduct post-operative assessments and wound checks, measure visual outcomes, provide standardized post-op education, and escalate complications promptly to the surgeon.
Obtain and review outside records and diagnostic tests, reconcile medication lists, and prepare charts and imaging prior to provider visits to maximize clinic efficiency.
Maintain strict HIPAA compliance and patient confidentiality while managing protected health information and performing secure EHR documentation and messaging.
Accurately enter billing-relevant information, procedure modifiers, and CPT/ICD data points needed for ophthalmic testing and reporting to support coding and revenue cycle workflows.
Calibrate, clean, and maintain ophthalmic equipment daily (autorefractor, tonometer, OCT, phoropter, keratometer), document maintenance and service issues, and coordinate repairs with vendors to reduce downtime.
Participate in quality assurance initiatives including image quality audits, infection control rounds, and standardized testing competency checks to support clinic accreditation and JCAHPO standards.
Educate patients and caregivers about chronic eye diseases (glaucoma, macular degeneration, diabetic retinopathy) including medication adherence, home monitoring, red flags, and scheduling follow-ups.
Facilitate efficient patient flow by rooming patients, collecting vitals, placing test orders per standing protocols, and coordinating ancillary testing with subspecialty clinics (retina, glaucoma, cornea).
Administer or assist with topical ocular medication trials per physician orders, document responses and adverse events, and support clinical research or trial visit protocols when applicable.
Train and mentor new COAs, medical assistants, and optometry/ophthalmology students on clinic workflows, exam room setup, equipment use, and patient communication best practices.
Support surgical scheduling and pre-op clearance processes by confirming pre-op testing, recording vital signs, completing necessary consents, and communicating surgical instructions and arrival times to patients.
Assist with office-based visual field testing (Humphrey, Octopus), instruct patients for reliable testing, review reliability indices, and notify providers of invalid or borderline fields.
Ensure proper inventory management of ophthalmic supplies including drops, sterile trays, lenses, and surgical disposables; perform cycle counts and place supply orders to maintain stock levels.
Participate in multidisciplinary team huddles, communicate patient-specific concerns to providers, and contribute to process improvements that reduce wait times and enhance patient satisfaction.

Secondary Functions

Support clinical quality improvement projects, including data collection for outcomes, follow-up adherence, and patient satisfaction metrics.
Maintain and reconcile imaging and testing databases; export images and reports for referrals, consults, and medico-legal records requests.
Provide community outreach support by representing the clinic at vision screening events, school screenings, and educational seminars.
Assist front-desk staff with appointment triage, insurance verification, prior authorization processing for procedures and medications when required.
Participate in inventory procurement and vendor coordination for ophthalmic equipment and specialty supplies.
Contribute to development and maintenance of clinic policies, standard operating procedures (SOPs), and competency checklists for ophthalmic testing.
Support ad-hoc requests for clinical data and help prepare materials for provider case conferences and morbidity & mortality (M&M) reviews.
