Eye exam workflow
Structured VA, refraction, IOP, slit lamp, posterior segment and glaucoma assessment, with trend charts across every visit.
Ophthalmology · Practice management
Practice management, built for the eye clinic.
Lumen is a modern, ophthalmology-specific clinical system for Australian practices. DICOM imaging, injection tracking, IOL calculation, refraction workflow and MBS billing - in one secure, cloud-native platform.

Purpose-built for ophthalmology.
Most practice management software treats ophthalmology as one specialty among dozens. Lumen does the opposite. Every screen, template and field is designed around how eye clinics actually work - the cadence of intravitreal injections, the cycle of refractions, the conversation between consult and theatre.
The result is software that fits the way ophthalmologists think, instead of the other way round.
The depth a generalist PMS cannot match.
Lumen ships with the workflows, calculators and data structures ophthalmology actually needs - not generic templates retrofitted from a broader product.
DICOM imaging
OCT, visual fields, fundus and biometry viewed in-browser via Cornerstone.js. Hosted in Australian object storage.
Injection tracker
Treat-and-extend interval calculator, VA trend overlay, and intravitreal item billing prepared with each visit.
IOL calculator
Barrett Universal II, SRK/T, Haigis and Hoffer Q - biometry imported from Zeiss IOLMaster, Tomey and Lenstar.
Eye diagrams
Clickable anterior and posterior segment diagrams with drawing tools for retinal tears, PRP and lesions - saved with every encounter.
Versioned notes
Every save is a new immutable version. Full history, full accountability - written for clinicians who care about defensibility.
Designed to fit the infrastructure your practice already uses.
Lumen integrates with the Australian healthcare stack as a first-class citizen - not an afterthought. Some integrations are shipping with the platform; others are progressing through Australian government conformance queues in parallel.
- MBS Billing Current schedule, item picker, multi-operator and bilateral rules, bulk-bill and DVA. Shipping
- Medicare claiming Tyro Health bridge from day one; native ECLIPSE conformance in the pipeline. In progress
- Medical Objects Secure inbound & outbound HL7 for referrals, pathology and correspondence. In progress
- My Health Record ADHA conformance underway - consult and discharge summary upload. Conformance
- HI Service IHI, HPI-I and HPI-O lookups, pending Services Australia approval. Pending
- SMS reminders Appointment confirmations, no-show reduction and recall workflows. Shipping
- ICD-10-AM & SNOMED CT-AU Coded diagnosis from a clinician-curated favourites list. In progress
- VIP.net migration Full-clinic import path for practices leaving Best Practice VIP.net. In progress
Healthcare-grade, by default.
Compliance is in the architecture, not the marketing. Lumen is built to the standards Australian clinical software actually needs.
Hosted in Australia
All clinical data resides in AWS ap-southeast-2. Data sovereignty is non-negotiable.
Encrypted end to end
AES-256 at rest, TLS 1.3 in transit. Encrypted backups, encrypted Bridge Agent cache.
MFA & Argon2id
TOTP multi-factor mandatory for clinical users. Argon2id hashing, refresh-token theft detection.
Database audit trail
Every read and write on clinical data captured at the database layer, retained for 7 years - longer for minors and implant records, per the privacy notice.
Versioned, not overwritten
Clinical entries are versioned and soft-deleted, never silently overwritten. Transient data is purged on a short cycle, and records are destroyed or de-identified at the end of their lawful retention period (APP 11.2).
External security testing
An independent OWASP Top 10 penetration test by an external firm is planned before general availability.
Currently in private pilot.
Lumen is in active development with a small group of Australian ophthalmology practices. Government conformance applications - Services Australia ECLIPSE, ADHA My Health Record, Medical Objects, HI Service and NASH PKI - are progressing in parallel.
If you'd like to follow the build or join the next pilot cohort, we'd be glad to hear from you.
