Digi Chemist vs Angle Alpha Patwardhan

We are here to improve the standard of scientific skincare in India, using the science, experience and empathy to enhance the natural radiance of your skin.

Angle Alpha is a clinical planning tool for eye-care professionals performing toric IOL and cataract surgery. Photograph the patient's eye with the camera (or import an existing image), overlay a scaled protractor and reference grid, and read off the ophthalmic measurements you need for accurate toric lens alignment — right on your phone, with no extra hardware. Conceived and owned by Dr. Sourabh D. Patwardhan and developed by ScriptLanes. WHAT YOU CAN MEASURE • White-to-white (WTW) diameter as the scaling reference • Pupil diameter • Alpha and Kappa distances • X / Y offsets in millimetres • A draggable axis-of-placement / mark-rotation line for toric alignment HOW IT WORKS 1. Capture the eye with the camera or pick an image from your gallery. 2. Enter the white-to-white (WTW) value to calibrate the on-screen scale. 3. Align the overlay grid and read the live measurements. 4. Drag the placement-axis line to plan or verify toric marking. 5. Save the annotated result against a patient record for later review. PRIVACY BY DESIGN Everything you capture or enter stays on your device. There are no accounts, no ads, no analytics, and no third-party tracking. The app has no backend and never transmits your data or your patients' data. MEDICAL DISCLAIMER Angle Alpha assists clinical judgement and is not a substitute for professional diagnosis, examination, or treatment. The clinician assumes all responsibility for use of, and results obtained from, the app.
