Patients diagnosed with early keratoconus and under the age of 25 who underwent to I-CXL were retrospectively reviewed and included in the study if they fulfilled the following criteria: high visual acuity (LogMAR ≤ 0.2) before I-CXL and the fact that the fellow, most advanced eye, had been treated with epithelium off CXL (S-CXL). Corrected distance visual acuity (CDVA), spherical equivalent refraction, thinnest corneal thickness, corneal topography and tomography were assessed at baseline and at least 24 months of follow-up, using Pentacam. Statistical analysis was performed with STATA SE version 17.Results: Twenty patients with a mean age of 18.5 ± 3.75 months were included. The median follow-up time was 24 months. The statistical analysis showed no significant change over time in CDVA, maximum keratometry and A, B, C values of the Belin Progression Display. Mean baseline CDVA was 0.03 ± 0.07 logMAR, whereas at 24-month was 0.01 ± 0.04. Mean spherical equivalent was − 1.29 ± 1.38D at baseline and − 1.05 ± 1.51D after 24 months. Preoperative maximum keratometry was 48.35 ± 4.95 D and 48.56 ± 4.96 D after the 2 years of follow-up. Mean baseline A value was 7.13 ± 1.66 mm and 24-month postoperative was 7.43 ± 0.48 mm. Average B value was 5.87 ± 0.55 mm prior to surgery, while it was 5.83 ± 0.60 mm after the last follow-up. Mean baseline and 24-month thinnest point were 498.9 ± 34.29 μm and 500.10 ± 33.45 μm respectively. None of the patients showed a progression of keratoconus.Conclusion: I-CXL may be considered as a beneficial treatment option for young patients with less advanced keratoconus, although further consensus on patient selection criteria is needed.Keywords: keratoconus, ectasia progression, cross-linking treatment, iontophoresis |
