About

Angle Alpha Patwardhan

Features
Read full description

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 β€” right on your phone, with no extra hardware. Conceived and owned by Dr. Sourabh D. Patwardhan and developed by ScriptLanes. WHAT YOU CAN MEASURE β€’ White-to-white (WTW) diameter as the scaling reference β€’ Pupil diameter β€’ Alpha and Kappa distances β€’ X / Y offsets in millimetres β€’ 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.
