摘要

This retrospective, observational case series aimed to evaluate the one-year outcomes of Implantable Collamer Lens (ICL, STAAR Surgical, Nidau, Switzerland) implantation for myopic regression following laser vision correction. We assessed patients who underwent ICL implantation to correct myopic regression after corneal refractive surgery. Visual and refractive outcomes, corneal higher-order aberrations (HOAs), and endothelial cell counts were also evaluated. A total of 66 eyes from 34 patients with spherical equivalent ranging from − 4.50 to − 1.00 diopters (D) were included. At one year, A Snellen uncorrected distance visual acuity (UDVA) of 20/20 or better was achieved in 94% of the eyes, and no loss of corrected distance visual acuity (CDVA) was observed. The efficacy index (postoperative UDVA/preoperative CDVA) and safety index (postoperative CDVA/preoperative CDVA) were 1.08 and 1.09, respectively, and the mean spherical equivalent were − 0.16 ± 0.28 D. Additionally, 98% of eyes achieved spherical equivalent refractions within ± 1.00 D, and all eyes had residual astigmatism within 1.00 D. Keratometry, endothelial cell density, and HOAs exhibited no significant changes (p > 0.05). According to our experience, ICL implantation appears to be a safe, effective, and predictable treatment option for correcting myopic regression particularly in cases with insufficient residual stromal thickness after laser vision correction, while maintaining visual quality without increasing corneal HOAs.
