Identify Independent Predictors of Poor Prediction (Steeper K2, Greater Objective Cylindrical Power)
Case Study: Identifying High-Risk Profiles for AI Refraction
A 45-year-old patient presented with high objective cylindrical power and steeper keratometry (K2=45.50D). Our AI model initially predicted a refraction with errors exceeding clinically acceptable thresholds. Upon full subjective refinement, a subtle oblique astigmatism was identified that was not fully captured by the initial objective measurements, leading to a significant prediction error by the AI. This highlights that while the AI is highly accurate in most cases, specific corneal characteristics and higher cylindrical complexity serve as important indicators for clinicians to perform full subjective refinement, ensuring optimal patient outcomes.
Key Takeaway: Steeper keratometry (K2) and greater objective cylindrical power are independent predictors of poor AI prediction accuracy, signaling the need for traditional subjective refinement.
