Optometrist prescribing authority exists in every U.S. state, but what a given optometrist can actually prescribe depends on two layers of rules: the state’s Optometry Practice Act, which sets the clinical scope, and federal DEA registration, which governs any controlled substance a state has authorized. Topical and oral eye medications are broadly available to optometrists nationwide. Controlled substances are not: roughly 35 states permit Schedule II hydrocodone combination products along with Schedules III through V, about nine states cap authority at Schedules III through V, and the remaining jurisdictions allow only Schedule IV and V medications or none at all.
How State Practice Acts Set the Scope
Each state’s Optometry Practice Act draws the line between what a licensed optometrist can and cannot do. The statute names the medications within reach, lists the qualifications a practitioner must hold before prescribing, and hands enforcement to a state Board of Optometry. Boards investigate complaints and act against practitioners who step outside the authority the statute grants them.
Most states use a tiered certification system. Diagnostic Pharmaceutical Agents (DPA) certification covers medications used during an exam, such as dilation drops and topical anesthetics. Therapeutic Pharmaceutical Agents (TPA) certification covers medications prescribed to treat disease. Nearly all actively licensed optometrists now hold TPA certification, because every state grants some level of therapeutic prescribing. State legislatures have kept expanding these statutes, and in 2025 several states passed further changes, including new laser privileges and the removal of prescribing certification barriers.
Consequences for violating a practice act range from fines and mandatory remedial education up to license revocation. Boards must report serious adverse actions to the National Practitioner Data Bank within 30 days, so a suspension or revocation in one state follows a practitioner’s record everywhere else.1National Practitioner Data Bank.

Topical and Oral Medications
The core of optometric prescribing is topical: drops and ointments applied directly to the eye. That includes antibiotics for bacterial conjunctivitis, antivirals for herpetic keratitis, corticosteroids and NSAIDs for inflammation or post-surgical care, and the long list of prostaglandin analogs, beta-blockers, and related agents used to manage glaucoma pressure over the long term.
All 50 states also allow optometrists to prescribe oral medications, though the categories vary. Oral antibiotics and antivirals are the most commonly authorized, covering conditions like preseptal cellulitis or shingles affecting the ophthalmic nerve. Some states cap the days’ supply for acute prescriptions and expect a referral if the patient doesn’t improve within that window. Others allow oral steroids for a limited duration without requiring physician consultation. Restrictions have loosened steadily over time, with topical-only states gradually opening the door to systemic medications.
Controlled Substances and DEA Registration
Two conditions have to line up before an optometrist can prescribe a controlled substance. The state practice act has to authorize it, and the practitioner has to hold an active DEA registration. The DEA classifies optometrists as “mid-level practitioners,” meaning federal authority tracks whatever state law permits.2Drug Enforcement Administration. Mid-Level Practitioners Authorization by State The DEA number by itself does not grant prescribing rights; it verifies state authorization and provides the tracking system. Anyone who dispenses controlled substances must register unless a regulation specifically exempts them.3eCFR. 21 CFR 1301.11 – Persons Required to Register
Which Schedules Are Available by State
State laws fall into three broad tiers. About 35 states authorize Schedule II hydrocodone combination products together with Schedules III through V. Another nine states limit optometrists to Schedules III through V. The remaining jurisdictions restrict authority to Schedules IV and V or grant no controlled substance authority at all.4National Conference of State Legislatures. Prescription of Controlled Substances Where Schedule II is on the list, it is almost always limited to hydrocodone combination products specifically, not the full range of Schedule II drugs.
Supply Limits
Even in states that permit Schedule II prescribing, the quantity is capped. Some states restrict hydrocodone prescriptions to a 72-hour supply. Others allow up to five days.4National Conference of State Legislatures. Prescription of Controlled Substances The caps are meant to hold down addiction risk for medications typically prescribed for acute ocular pain, and exceeding them draws action from both the state board and the DEA.
Prescription Drug Monitoring
Most states require prescribers to query the state Prescription Drug Monitoring Program before writing a controlled substance prescription. Some require a check before every controlled prescription; others require one only when clinical judgment suggests a risk of misuse. Optometrists with controlled substance authority follow the same PDMP rules as other prescribers in their state.
Federal Penalties
Prescribing controlled substances without a valid DEA registration is a federal offense. A first violation of the prohibited-acts provisions carries up to one year of imprisonment, rising to two years for a second offense.5Office of the Law Revision Counsel. 21 USC 842 – Prohibited Acts B If the conduct amounts to unauthorized distribution of Schedule I or II substances, the exposure climbs to 20 years of imprisonment and fines up to $1,000,000 for an individual.6Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A The DEA reports registration actions to the National Practitioner Data Bank within 30 days.1National Practitioner Data Bank. What You Must Report to the NPDB
Federal Training and E-Prescribing Rules
Every DEA-registered practitioner must complete a one-time, eight-hour training course on treating patients with opioid or other substance use disorders. The MATE Act requirement applies to all registrants regardless of prescribing volume, and the training has to cover clinical use of FDA-approved medications for substance use disorders. Practitioners attest to completion by checking a box on the DEA registration form. The DEA does not collect the certificate, but practitioners should keep documentation in case of audit. Accepted training comes from bodies such as the Accreditation Council for Continuing Medical Education or the Commission for Continuing Education Provider Recognition.7Drug Enforcement Administration. Opioid Use Disorder – MATE Act Q&A This is separate from continuing education hours required for state license renewal.
On the electronic prescribing side, CMS requires prescribers to electronically transmit at least 70% of their Schedule II through V controlled substance prescriptions under Medicare Part D. The rule phased in starting in 2023 and is fully enforced for the 2026 measurement year.8eCFR. 42 CFR 423.160 – Standards for Electronic Prescribing Measurement runs January 1 through December 31 using Medicare claims data, with no separate submission.9Centers for Medicare and Medicaid Services. CMS EPCS Program Requirement At-A-Glance Most optometrists qualify for an automatic exception, because CMS exempts any prescriber who writes 100 or fewer qualifying Medicare Part D controlled substance prescriptions during the measurement year. Separate exceptions apply for prescribers in federally declared disaster areas. Prescribers who miss the 70% threshold without an exception receive a non-compliance notice the following fall, and CMS may factor persistent non-compliance into fraud, waste, and abuse assessments that can eventually affect billing privileges.
When an Optometrist Exceeds Prescribing Authority
State boards can respond with fines, mandatory additional education, practice restrictions, probation, suspension, or license revocation. If a practitioner surrenders a license while under investigation, the surrender is treated the same as a formal adverse action for reporting.
Reporting obligations tie the state and federal systems together. Malpractice payments made on behalf of an optometrist must be reported to the National Practitioner Data Bank within 30 days, and so must any adverse licensing action by a state board or controlled substance registration action by the DEA.1National Practitioner Data Bank. What You Must Report to the NPDB Hospitals, professional societies, and peer review organizations query the Data Bank when credentialing, so an optometrist who loses prescribing privileges in one state cannot relocate and start fresh without the new state’s board seeing the prior action.
Procedures Are a Separate Question
Prescribing authority does not automatically bring procedural authority. State law addresses procedures separately, and the picture varies.
Foreign body removal is authorized in the vast majority of states.10National Conference of State Legislatures. Authority to Perform Ophthalmic Procedures Injectable authority is more variable: many states allow injections around the eye, including local anesthetics and steroid injections into eyelid lesions, and many also permit epinephrine auto-injection for anaphylaxis during treatment. A few states go further, authorizing botulinum toxin and even vaccine administration. Where injectable authority exists, states commonly exclude intravenous and intraocular injections that penetrate the globe.11National Conference of State Legislatures. Injectable Authority
Laser surgery is the most contested area. Roughly a dozen states now authorize optometrists to perform certain laser procedures, with more added recently.10National Conference of State Legislatures. Authority to Perform Ophthalmic Procedures The most commonly authorized are YAG capsulotomy, which clears cloudy tissue that forms behind an artificial lens after cataract surgery, and Selective Laser Trabeculoplasty (SLT), which lowers eye pressure in glaucoma patients. A smaller set of states allows laser peripheral iridotomy, and a few permit photorefractive keratectomy (PRK) for vision correction. Performing any of these requires specific clinical certification beyond the standard optometric license, along with documented training hours and equipment safety compliance.
