A pocket toolbox for ophthalmology. A surgical logbook and thirteen clinical tools — handbooks, screening tests, calculators, and cameras — in one native app for iPhone and iPad. Built for ophthalmologists, optometrists, opticians, orthoptists, residents, and medical students. Designed for the bedside, the clinic, and the operating room. Every tool is one tap away. SURGICAL LOGBOOK Log each case in seconds: procedure, eye, role, supervisor, and hospital, from more than 70 eye procedures or your own. Record the steps you did and any complications, and attach the IOL calculation, photos, videos, and PDFs. Stats show totals by procedure and role, cataract steps, and your complication rate. No patient names or MRNs, with optional iCloud sync. POCKET HANDBOOKS • Eye Exam Guide The eye examination in 13 step-by-step chapters, from history taking to the slit lamp, gonioscopy, and the dilated fundus. Normal values, how to record findings, common pitfalls, 85 photos and diagrams, and linked references. • Eye Drops Guide A searchable reference to more than 100 eye medications in seven categories, from antibiotics and glaucoma drops to allergy, dilation, and dry eye. Doses, forms, brands, safety, and interactions, checked against US, UK, and Saudi labels. BEDSIDE TOOLS • VA Conversion Table Meter, feet, and decimal acuities side by side. • Retina Viewer Smartphone fundus photography with a 20D lens: live zoom, photos or video, saved to Photos. • Nine-Gaze Camera Guide the patient through the nine cardinal gaze positions for a 3×3 motility montage. • Ishihara Test 24-plate color vision screening with a 1–15 scoring table, protan/deutan classification, and linked validation studies. • IPD Measurement Interpupillary distance with the TrueDepth front camera. • Amsler Grid On-screen central vision testing for macular monitoring. • Cobalt Blue Screen Blue light for fluorescein when no cobalt blue source is at hand. CLINICAL CALCULATORS Live results as you dial in values, with the formulas and published sources behind every answer. • Age to Bifocal Add A tentative near add at 40 cm from the patient's age, with the full age-band table. • Rx Toolkit Transpose cylinder, find the spherical equivalent, and vertex-compensate between spectacle and contact lens powers, rounded to steps you can order. • Prism Toolkit Prentice's rule for both lenses: vertical imbalance at the reading level, PD-error prism graded against ANSI Z80.1, and prism by decentration. • AC/A Ratio Calculated and gradient methods side by side, the binocular vision pattern the findings fit, and how a near add will shift the near phoria. DESIGNED FOR CLINICIANS Short workflows and help sheets that spell out technique and limitations. Home Screen quick actions open VA Conversion, Search Medications, and Cobalt Blue Screen. On iPad, a sidebar keeps every tool in view, with keyboard shortcuts. A NOTE ON SCOPE Ophthalmology Toolbox is a clinical reference and screening companion. It does not replace slit-lamp examination, formal perimetry, or standard equipment when available. The Cobalt Blue Screen and digital Ishihara test are bedside workarounds, with printed plates or proper equipment used to confirm significant findings. The Eye Exam Guide supports supervised training, and the calculators support clinical judgment; neither replaces them. JUST THE BEGINNING More tools and handbooks are on the way. If something's missing from your workflow, send a note. MEDICAL DISCLAIMER: This app is intended for educational, informational, and clinical reference purposes only. It does not provide medical diagnosis or treatment and is not a substitute for professional medical advice, clinical judgment, or consultation with a qualified healthcare professional.
