Contact Lens Fit Intelligence
Refraction + keratometry + corneal measurements + ocular-surface preference → lens parameters, then commercial availability across the product database.
Professional Clinical Support
Refraction
Enter the spectacle prescription (vertex conversion is applied per principal meridian) or switch to an already-converted contact lens Rx.
Right eye · OD
Left eye · OS
Spherical workflow — sphere power only. Cylinder and axis are not used and no toric correction is calculated.
OD and OS K1 / K2 in dioptres or millimetres.
HVID, visible iris, and optional corneal diameter.
Tear film / ocular surface
A product-filtering preference — not a clinical classification.
Balanced filtering: material, oxygen transmissibility, water content, base curve, diameter, power availability and replacement schedule are weighted together.
Fitting preferences
One-tap filters applied to the database.
Lens type
Wearing schedule
Material
Priorities (multiple allowed — affects ranking only)
Database search
Manufacturer, brand, model, BC, diameter, power, ADD, material.
Calculated contact lens Rx
Stage 1 — mathematics only

Clinical warnings
- • Enter at least one eye's prescription to search the database.
Preferred lens parameters
Base curve and diameter are taken from each manufacturer's published options and fitting guidance. OptiX Pro deliberately applies no universal rule such as “K 43.50 → BC 8.60”, because soft lens base curve selection depends on lens design and manufacturer.
Analysis Results
Enter the prescription, keratometry, HVID and preferences, then tap Analyze candidate lenses. OptiX Pro converts the prescription, analyses the cornea, filters the database and reports which commercial parameters are actually available.
Clinical verification required
Important: parameter matching does not establish clinical fit. Contact lens movement, centration, coverage, comfort, tear film, corneal physiology, visual performance, over-refraction and manufacturer fitting guidance must be assessed clinically. Final lens selection, fitting assessment and clinical suitability require appropriate professional evaluation and on-eye verification.
OptiX Pro is an optical calculation and clinical support tool for students and eye-care professionals. Candidate product information is provided for professional consideration. Final lens selection, clinical suitability, fitting assessment and prescription require appropriate professional evaluation and on-eye verification.
Database quality control
Verify products against manufacturer documentation, add your stock, or import a CSV.
OptiX Pro provides mathematical calculations, reference information, and fitting assistance. It does not replace professional clinical examination, manufacturer fitting guidelines, or professional judgement. Contact lens selection and prescription must be clinically verified.
