Deep Learning Algorithms May be Beneficial in Screening Candidates for Refractive Surgery

In this diagnostic, cross-sectional study, 6465 corneal tomographic images from 1385 patients were examined. Pentacam InceptionResNetV2 Screening System (PIRSS), a tomographic-based screening tool, was developed to screen potential patients for refractive surgery. On the validation data set, the model achieved an overall detection accuracy of 94.7%. On the independent test data set, the model achieved an overall detection accuracy of 95%, which is on par with a senior ophthalmologist who specializes in refractive surgery (92.8%).

The model also performed better than classifiers in identifying corneas with contraindications for refractive surgery (95% vs 81%; P  < 0.001) in this population.

The authors concluded that the PRISS model appears to be useful in providing corneal information and identifying at-risk patients and may provide guidance to refractive surgeon in screening candidates.
