Objective:
To provide a systematic approach for troubleshooting issues in orthokeratology lens fitting.
Approach:
- Connecting the Dots: Correlate patients’ subjective symptoms with axial and tangential difference maps to identify discrepancies.
- Central Islands: Reduce sagittal depth to correct excessive vaulting causing poor vision.
- Decentration Issues: Adjust sagittal depth to correct inferior or superior decentration.
- Undertreatment and Overtreatment: Adjust the treatment target without rebuilding the lens.
- When No Action Is the Best Action: Observe if the patient is comfortable and sees well, even with an imperfect map.
Key Findings:
- Smaller back optic zone diameters can enhance myopia control outcomes.
- Excessive sagittal depth can lead to central islands and poor vision.
- Inferior decentration indicates a lens that is too steep, while superior decentration indicates a lens that is too flat.
- Adjusting the treatment target can correct refractive errors without redesigning the lens.
Interpretation:
A systematic approach is essential for troubleshooting orthokeratology lens fitting issues, considering both subjective symptoms and objective measurements.
Limitations:
- Not every lens fit issue requires immediate redesign; some cases may require observation.
Conclusion:
Effective troubleshooting in orthokeratology involves a careful analysis of both patient feedback and clinical data.
