Comparative study reveals distinct corneal stiffness patterns across post-refractive surgery and keratoconic eyes, suggesting differential biomechanical stability after laser procedures.
Keratoconus eyes were significantly softer when compared to post-refractive surgery corneas with comparable corneal thickness in terms of SP-A1 and BAD-D values, while the LASEK group may have the greatest stiffness. Post-SMILE and post-LASEK corneas showed significant differences in SP-A1.
