NexaNeura

AI Agents for Ophthalmology

Your hospital runs its cataract pathway on the phone: conversion callbacks, pre-op prep, post-op follow-up, recalls. NexaNeura automates those workflows end to end with AI voice agents that speak the patient's language, and puts every outcome back in front of your team.

नमस्ते, रीति आई केयर से बोल रही हूँ। डॉक्टर साहब ने आपकी मां की आँख के ऑपरेशन की सलाह दी थी। ताऱीख़ तय हो गई? The doctor advised your mother's cataract surgery. Has a date been fixed?
उन्हें अस्पताल कौन लेकर आएगा? मुझे हफ़्ते में छुट्टी नहीं मिलती। Who will bring her to the hospital? I cannot get leave during the week.
शनिवार को भी ऑपरेशन होता है। सुबह सात बजे आइए, दोपहर तक घर पहुँच जाएँगे। इस शनिवार या अगले? We operate on Saturdays too. Come at seven, home by afternoon. This Saturday or next?

Workflows

AI voice agents: eight workflows, from referral to second eye

The full cataract journey as your hospital actually runs it. Pick any stage to see what the agent does and hear it on a real call. Each workflow switches on independently, and nothing gets re-plumbed when you add the next one.

Workflow 01 of 08

Referral capture

  • Calls within 48 hours of a referral from your vision centre, optical partner, or camp
  • Explains in the patient's language why the doctor wants them seen at the hub
  • Offers a slot and settles transport and escort on the same call
closes network leakagewithin 24–48h of referral

How it works

Workflow automation, with a voice

NexaNeura is not a chatbot or a reminder tool. It is the phone workflows your hospital already runs, executed by AI voice agents instead of an overstretched telecalling desk.

Your system sends the list

A nightly export of who was advised surgery, who is booked, who was operated, and who is due back. Read-only, and we build the connector for whatever hospital system you run.

Voice agents work every patient

Calls in the patient's language, on the right day, with the right script for that stage. Retries on schedule, calls the attendant when the family decides, and stops when asked.

Outcomes land back with your team

Bookings in the counsellor queue, red flags with the duty doctor, confirmations on the OT list. Every call recorded, transcribed, and reported.

Platform

Built for Indian eye hospitals

Speaks the patient's language

Hindi, Kannada, Telugu, Tamil, Marathi, Bengali. And it calls the family member who actually decides, not just the patient.

Runs on a daily export

A nightly list from the system you already run is enough to start. No new software for your staff to learn.

Deploys inside your VPC

Patient data, recordings, and transcripts stay in your own cloud tenancy, in India, under your retention policy.

Clinician-signed protocols

Our Head of Medical authors every symptom list and escalation rule, countersigned by your surgeon. The agent never diagnoses and never prescribes.

Clinical safety

What happens when a patient reports a symptom

Post-operative calling is the one workflow that touches clinical risk, so the architecture is published rather than buried. Severity is assigned by a fixed rule set an ophthalmologist wrote. The model never decides how urgent something is.

No workflow that touches a symptom goes live until Dr. R. Poornika, our Head of Medical, has authored the protocol and your own ophthalmologist has countersigned the escalation table, including who holds the duty phone at night and on Sunday.

Dashboards

Everything the agents do, in one view you can govern

Your team does not log into a new system to work. They log in to check. Three views: where patients sit in the pathway, what the agents did today, and every clinical escalation with the time it took to reach a human.

Every stage is clickable in the live console down to the individual patient, the calls placed, and what the agent was told.

Why NexaNeura

A general-purpose voice bot cannot run a cataract pathway

Most healthcare voice AI answers the phone. That is a receptionist problem. Ours is a clinical operations problem: knowing that the day-3 call matters more than the day-1 call, that the escort is the barrier and not the price, and that the second eye is worth more than the first enquiry.

Generic voice AI and front-desk bots

Answer calls, book slots, send reminders

  • Inbound first. Waits for the patient who has already decided to call.
  • Specialty-agnostic scripts, so no idea what a biometry or a YAG is.
  • English and Hindi chat, tuned for smartphone users rather than a 68 year old on a feature phone.
  • No clinical governance, so nothing that touches a symptom can go live.
  • Built for US or EU electronic records, not the systems Indian eye hospitals actually run.
NexaNeura

Runs the eight workflows that decide whether a patient reaches theatre

  • Outbound by design. We work the patients who did not call back, which is where the lost revenue actually sits.
  • Ophthalmology only. The pathway, the timings, and the barriers are encoded, from lens counselling to second-eye eligibility.
  • Vernacular for this population. Six languages, written for elderly patients on ordinary handsets, and it calls the attendant separately.
  • Clinical governance built in. Tiered symptom screens, a named duty doctor, an SLA, and a signed protocol before go-live.
  • India-native deployment. Your VPC, your data residency, your carrier, DPDP as processor, and a connector for the system you already run.
Impact

What a year of closed workflows returns

Every recovered patient below already chose your hospital, saw your surgeon, and was told they need an operation. The acquisition cost is spent. The workflows bring them the rest of the way. We label what is modelled and what is measured, because the two are not the same thing.

Modelled 150–200 extra surgeries a year from conversion recovery and second-eye recall, at a hospital already doing 3,000 cataracts.
Modelled ₹45L–1.2Cr recovered surgical revenue before counting spectacles at the optical counter and the second eye's own downstream value.
Measured in pilot 3 weeks to your first real number pre-op coordination goes live first, and the day-of cancellation rate moves against your own prior baseline.
The model, stated in full
  • 3,000surgeries a year at the hospital
  • ~2,000patients advised surgery who never booked
  • 8–10%of them recovered by calling
  • ₹30–60krealisation per surgery
How we turn the model into evidence
  • 70 / 30your unconverted cohort is split at random: called, and deliberately not called
  • Deltawe report only the difference between the two groups, never the gross total
  • Monthlyresults go to you whether or not they favour us, including the months they do not
  • Yoursthe holdout data is your hospital's, and you can audit our arithmetic against it
Beyond cataract

Cataract is the first pathway, not the whole company

Live

Cataract

Eight workflows from referral to second eye. Closes once, at the second eye, then returns the patient for lifelong review.

Next

Retina, anti-VEGF

Injection cycles every four to twelve weeks, indefinitely. Around half of Indian patients drop out of the cycle, and missing a dose costs vision permanently.

Planned

Glaucoma

Decades of follow-up and daily drops with no end point. Adherence and review attendance are both poor, and the vision lost is never recovered.

Planned

Diabetic retinopathy

Annual screening recall on the hospital's own diabetic base, where the relationship already exists and the recall is the entire intervention.

Team

Clinicians and engineers, in the same room

Health tech built without a doctor on the inside gets the workflow wrong. Our Head of Medical is a practising ophthalmologist who authors and signs every clinical protocol the agents run.

FAQ

Questions hospitals ask us

What happens to our existing telecalling team?

Nobody is replaced. Your counsellors and telecallers keep doing what they are best at, which is closing the patient in front of them. NexaNeura works the list they never reach: the patient who left without booking, the day-60 callback, the second eye, the uncollected spectacles. It hands warm, confirmed intent back to your team with full context, so the same headcount converts more. In practice your telecallers stop dialling cold lists and start working qualified ones.

Does it integrate with our hospital system?

Yes, and it does not require an integration project to begin. A scheduled nightly export is enough: patient name, phone, preferred language, attendant contact, what the surgeon advised and for which eye, booking status, and surgery and review dates. Read-only. We build the connector against whatever system you run. Write-back for slots and notes comes later, when you want it, never as a precondition.

How much work is this for our IT team?

One scheduled export, typically half a day of work for whoever maintains your hospital system, and a single call with us to agree the fields. There is no software for your staff to install or learn. Outcomes arrive in your existing counsellor queue and as a daily report.

Which languages does it speak?

Hindi and Kannada today, with Telugu, Tamil, Marathi, and Bengali configured per site. The agent asks the patient's preference on the first call and remembers it. Scripts are written for older patients on ordinary handsets, not smartphone users, and the speech models are tuned for that population rather than for clean studio audio.

What happens when a patient reports pain after surgery?

The post-operative call runs a fixed, tiered symptom list authored and signed by our Head of Medical and countersigned by your own surgeon. A red-flag answer ends the screen immediately and reaches your duty doctor within an agreed time target. An ambiguous answer is treated as the more serious tier. A call that drops mid-screen, or a patient we cannot reach inside the day-3 window, triggers a human callback the same day. The agent never tells a patient a symptom is harmless outside your approved script.

Where does patient data live?

Inside your own cloud tenancy, in India. Your hospital remains the data fiduciary under the DPDP Act and we operate as your processor under a signed data processing agreement. Recordings and transcripts follow your retention policy, consent notices are delivered in the patient's language, and opt-outs propagate immediately and permanently across every workflow.
