Ophthalmology
Artificial Intelligence
Medical Imaging

Background:

Cataracts are a leading cause of blindness globally, necessitating early diagnosis.
Effective diagnostic tools are crucial for managing this high-prevalence eye condition.

Purpose of the Study:

To evaluate the diagnostic performance of deep learning (DL) for cataract detection and classification.
To compare DL accuracy against traditional machine learning and human expert performance.
To assess DL's potential for automated cataract diagnosis.

Main Methods:

Systematic literature search across major databases (PubMed, Embase, etc.) up to April 2025.
Quality assessment of included studies using QUADAS-2.
Bivariate mixed-effects models for meta-analysis and Deeks' funnel plots for publication bias.

Main Results:

Sixty-three studies were included; high risk of bias noted in patient selection and index tests.
Image-based DL achieved high sensitivity (96%) and specificity (98%) for cataract detection (AUC 0.99).
DL demonstrated strong performance in classification (sensitivity 94%, specificity 97%, AUC 0.99), but lower accuracy on external datasets (e.g., 87% sensitivity).

Conclusions:

Image-based DL shows high precision for cataract detection and classification, potentially outperforming traditional ML.
DL performance is comparable to human experts, indicating feasibility for automated diagnosis.
Limited validation data and generalization challenges warrant caution for broad clinical implementation.
