Enquiry Types Qualified

Every Appointment Type
Qualified and Prioritised.

The qualification engine captures appointment type, current prescription status, laser surgery interest, urgency symptoms, and insurance status — complete patient profile before your first call.

EYE
Laser Surgery Consultations
LASIK, LASEK, RLE — highest-value enquiry type. Patients who have researched extensively convert at the highest rate.
!!!
Emergency Eye Care
Sudden vision change, eye injury, flashes and floaters — auto-scored Hot and flagged for same-day contact.
RX
Prescription Glasses & Lenses
Contact lens and glasses patients — high volume, recurring revenue, strong loyalty and lifetime value.
KID
Children's Eye Tests
Parental urgency drives fast decisions. NHS-funded tests plus private frame sales and myopia management.
REF
Cataract & Specialist Referral
Patients needing surgical referral — complex cases with high trust and long-term care pathway value.
DRY
Dry Eye Treatment
Chronic condition requiring ongoing management — recurring treatment relationship with high retention.
MYO
Myopia Control
Children's myopia management — specialist niche with growing demand and long patient relationships.
VIP
Designer Eyewear
Fashion-driven purchases — high-margin, often impulse-adjacent when prescription renewal is due.
Data Pipeline

From Enquiry to
Structured Alert in 200ms.

Built on AWS serverless infrastructure by an MSc Cloud Computing graduate — every lead flows through a production-grade pipeline with sub-200ms response times, 99.9% uptime, and zero maintenance overhead.

A HTTPS POST fires to API Gateway containing appointment type, current prescription status, laser surgery interest, urgency, vision symptoms, and insurance status — complete profile in one submission.
02
Lambda Scores the Lead
Laser surgery consultations and emergency eye care auto-score highest. Long-term contact lens wearers exploring laser also weighted high — research phase complete, ready to commit.
03
DynamoDB + Sheets Write
Patient record written to DynamoDB with UUID partition key and simultaneously synced to your private Google Sheet — both operations complete before the SES alert fires.
04
SES Alert Dispatched
Formatted HTML alert fires containing appointment type, prescription details, laser interest, urgency symptoms, and contact details. Emergency cases and laser consultations flagged in the subject line.
