Someone who books an eye appointment almost always forgets the pupil may be dilated and shows up driving. The agent warns beforehand, books the time and answers questions about exams and surgery.
Before you start, see the AI agent demos and the CRM with clinic examples.
What is the best WhatsApp chatbot for ophthalmologists in Brazil?
The best WhatsApp chatbot for ophthalmologists in Brazil is the one that answers on the number the clinic already uses, with the business rules written by you. A WhatsApp AI agent for an ophthalmologist is the CertuAI automatic assistant that books appointments and exams, warns when the patient needs to bring someone because of the eye drops that dilate the pupil, gives private-pay prices and insurance plan coverage, explains how the glasses prescription works and sends eye emergencies straight to the team.

Red eye with pain: where does the AI send them?
The CertuAI AI doesn't assess the eye, neither from a photo nor from a description. For “my eye is red”, it says in one sentence that it can't assess that here and offers an appointment or a handoff to the team.
The automatic urgency list is general, and wasn't built for the eyes: chest pain, shortness of breath, fainting, seizure, sudden slurred speech, weakness on one side of the body, bleeding that won't stop, or a big worsening. That's why you should write in the Brain the practice's rule for eye emergencies, such as a blow, a chemical or sudden vision loss: whether there is a fit-in slot, and which eye emergency room to send them to.
Does the AI promise a glasses prescription over WhatsApp?
No. On a health clinic account, the AI never issues or promises a prescription, report or exam order without an appointment. What it answers is what you wrote: whether the prescription is issued at the appointment, whether the eye exam is included, how much it costs.
How does the dilation notice arrive before the day?
Through the reminder. In CertuAI, the reminder goes out 24 hours and 1 hour before the confirmed appointment, and you can choose up to 3 times. The text is yours, so write in it: “come with someone, because your pupil may be dilated and you shouldn't drive afterward”.
Prefer the day before for this notice: that is when the patient can still find someone to come along. The reminder goes out near the chosen time, and can arrive a little after.
What does the AI do with each ophthalmology message?
| Message | What the AI does |
|---|---|
| "Will I need someone to come with me?" | Answers using your dilation rule |
| "My eye is red and burning, is it conjunctivitis?" | Doesn't assess; offers an appointment or a handoff to the team |
| "Cleaning product got in my eye" | Follows the eye emergency rule you wrote |
| "Send me the prescription again, I lost it" | Doesn't issue prescriptions; notes the request for the team |
| "How much is retinal mapping?" | Answers with the price list you wrote |

| Patient messages that arrived outside Monday to Friday, 8am to 6pm | 28,2% |
| Messages that arrived on the weekend | 11,2% |

What changes in the clinic with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the clinic before and after the CertuAI agent.
TodayPatient shows up driving without knowing the pupil would be dilated and has to wait hours
With CertuAIThe agent warns along with the confirmation, so they come with someone
TodayA question about the private appointment price sits until the front desk has time
With CertuAIAnswered right away, using the price list you maintain
TodaySomeone asking about refractive surgery gets a different explanation from each staff member
With CertuAIThe agent always explains the same way, your way
TodayPost-op return visit missed because nobody had time to call
With CertuAIThe patient asks for the return visit on WhatsApp and the agent books it right away, with a reminder beforehand
What does a conversation handled by the AI look like?
Example conversation
Clinic AI agent
Customer: Will I need someone with me because of the dilating eye drops?
AI agent: Yes. Since the pupil may stay dilated, come with someone and don't drive home. This notice goes along with the confirmation.
Customer: How much are retinal mapping and the visual field test?
AI agent: Retinal mapping and the visual field test are priced separately: your price.
Is an AI agent or manual service better for ophthalmologists?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the clinic has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Pupil dilation notice | Depends on the front desk remembering to warn on every call | Sent automatically along with the appointment confirmation |
| Price inquiry and private-pay exams | Answered when the front desk steps away from the counter | Answered right away, using the price list you maintain |
| Question about cataract or refractive surgery | Explained in full in every conversation | Explained your way, with the next step booked |
| Patient with red eye or trauma | Waits in the message queue along with people who only want a price | Separated right away and forwarded to your team to decide |
| Post-surgery return visit | Booked only if the patient remembers to call | The agent books the return visit in the same conversation and confirms the time beforehand |
What does the WhatsApp agent do for ophthalmologists?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Dilation notice with the booking
Every appointment that may end with dilated pupils goes out with the notice to bring someone and not drive home, written in the same message that confirms the time.
Price of each exam, not just the appointment
Refraction, retinal mapping, visual field, topography and OCT, each with the private-pay price you set and what insurance covers.
Glasses prescription and lens power recheck
The agent explains whether the prescription is issued at the same appointment, how long it is valid and the practice's policy for rechecking the lens power after the lenses are changed.
Cataract and refractive surgery conversation
Stages, the exams that come first and what changes between the available lenses, told in your words, with the evaluation booked at the end.
Eye emergencies outside automation
Trauma, sudden vision loss, flashes and new floaters leave the flow right away and go to your team, without the agent trying to answer.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the clinic no longer depend on you having your phone in hand.
How does the agent start answering at the clinic?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does a WhatsApp AI agent cost for ophthalmologists?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before turning the agent on at the clinic?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- Which types of appointment dilate the pupil and the text of the notice to bring someone and not drive home
- The private-pay price list for the appointment and each exam: refraction, mapping, visual field, topography and OCT
- The insurance plans accepted and which exams need authorization before the date
- The glasses prescription policy: whether it is issued at the same appointment, how long it is valid and how the lens power recheck works
- From what age you see children and what the family needs to bring
- The list of signs that take the conversation out of automation right away, with the path for outside business hours
Whether the agent books an exam directly in the equipment block or whether exams are only scheduled after the appointment takes place.
The most common mistake: Entering the exam only on the doctor's calendar. Visual field and OCT take their own room and machine, and two people booked in the same equipment block delay the whole afternoon even with the doctor free. Read how to fix this.
Ophthalmologist FAQ
Does the agent assess eye symptoms?
No, and red eye, severe pain, flashes of light or sudden vision loss leave automation right away. It records the report and calls your team, who decide on the fit-in.
Does it really warn about pupil dilation?
Yes, and it is the notice that prevents the most trouble. You mark which types of appointment dilate, and the agent sends the instruction to bring someone along with the confirmation.
Does it explain how long the glasses prescription is valid?
It repeats the policy you write, which is usually different for adults and children. The agent doesn't suggest a validity period on its own.
Can I separate the exam schedule from the appointment schedule?
Yes. Visual field and OCT have their own equipment and duration, so you set up each block and the agent fits into what is really free.
Other clinic questions CertuAI has answered
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
Books appointments and exams, warns about pupil dilation and gives prices. Each patient becomes a contact with history in the practice's CRM.
