In this paper, we introduce SmartKC++, a series of innovative methodological improvements to the image processing pipeline of SmartKC, aimed at significantly enhancing its diagnostic precision and reliability. Our comprehensive evaluation on a dataset comprising 303 eye images reveals that SmartKC++ boosts the accuracy of automated keratoconus diagnosis by 7.69% relative to SmartKC.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Keratoconus, an ocular condition marked by progressive corneal thinning and outward bulging, presents diagnostic challenges due to the high cost and lack of portability in conventional corneal topographers.
