Participants required a follow-up of at least four years. A total of 36 eyes (20 post-DALK, 16 post-PKP) were included. Collected data comprised demographics (age, gender, affected eye) and clinical characteristics (refractive error, corrected and uncorrected distance visual acuity [CDVA, UDVA], central corneal thickness, keratometry, surgical details, ablation depth, mitomycin duration, and complications).
