Low Vision Refraction Protocol & Prescription Optimization

What You Can Do
You can systematically document refraction findings for low vision patients and generate prescriptions optimized for specific functional tasks like reading, mobility, and facial recognition. The skill calculates appropriate magnification ratios, predicts realistic visual outcomes, and creates comprehensive documentation that prioritizes quality of life over distance acuity—transforming conventional refraction into patient-centered, task-driven prescriptions.
Features
identifies exactly what the patient needs to see (reading, mobility, hobbies) rather than generic acuity targets
implements low vision-specific techniques including higher magnification tolerance and functional endpoint criteria
computes precise magnification needed for each functional task with detailed optical formulas
forecasts realistic visual performance for specific activities based on refraction results
generates standardized clinical notes with prognostic statements and patient counseling points
presents near-vision aids, distance aids, and electronic magnification alternatives with comparative magnification ratings
provides evidence-based counseling frameworks to align patient goals with realistic outcomes
includes functional vision assessment checklists to measure real-world improvement post-prescription
Example Output
Patient Example: Macular Degeneration with Reading Goal
Refraction Summary:
- Best corrected acuity: 20/80 OD, 20/100 OS
- Manifest refraction: +2.50 −0.75 × 180 OD
- Low vision add for near: +8.00 (provides 8× magnification at 12.5 cm)
Functional Prescription:
- Primary recommendation: 8× hand magnifier with LED illumination (achieves N8 print, realistic for newspaper reading)
- Secondary option: 3× reading glasses with document camera + tablet display (8–10× digital magnification)
- Mobility aid: 2.7× bioptic telescope for pedestrian navigation
Outcome Prediction: Patient will read large-print materials independently at 8-point font size with adequate speed and comfort; standard print (10–12 pt) will require digital magnification.
Patient Example: Diabetic Retinopathy with Mobility Concern
Refraction Summary:
- Best corrected acuity: 20/150 OD, counting fingers 3 feet OS
- Manifest refraction: −1.25 −2.00 × 175 OD (optimal for mobility)
- Peripheral field: 40° remaining nasally, compromised inferiorly
Functional Prescription:
- Primary: 2.8× Keplerian telescope mounted on right side of glasses (for detecting curbs, stairs, oncoming pedestrians)
- Secondary: Contrast-enhanced bifocals for near tasks (simplified 3× add)
- Orientation notes: Keep periphery clear; telescope for threat detection only
Outcome Prediction: Patient will navigate familiar indoor environments with reduced stumbling risk; will need tactile cues or sighted guide for unfamiliar outdoor mobility.

You can create comprehensive, evidence-based perioperative pain management protocols tailored to individual patient characteristics and surgical requirements. The skill assesses patient risk factors, recommends optimized multimodal analgesia regimens with specific drug selections and dosing rationales, incorporates regional techniques when appropriate, and identifies contingency plans for inadequate pain control or contraindications. This enables you to move beyond generic guidelines toward truly personalized pain management strategies that reduce opioid exposure while maintaining analgesia.
