Background: The study aims to compare the refractive and topographic outcomes of keratoconic eyes treated with corneal collagen crosslinking (CXL) alone versus corneal collagen crosslinking (CXL) combined with Intacs implantation. Design: A prospective comparative study. Participants: The study recruited 38 eyes of 30 consecutive progressive keratoconus patients. Methods: In Group I, 24 eyes were treated with CXL alone and in Group II, 14 eyes underwent CXL combined with simultaneous femtosecond-assisted Intacs implantation. Visual acuity, refraction and corneal topography were assessed and compared between the two groups at baseline, 3 months and 6 months. Result: The mean age of participants was 26.5�±7.9 (range 15-51) years. The average of follow up was 6.66�±0.68 (range 5.5-8). At the final follow up, Group II (CXL combined with Intacs) resulted in an additional improvement of uncorrected distance visual acuity (UDVA) by 0.2 Log units (pâ�¤0.05), spherical power by 0.80 diopter (pâ�¤0.05) and cylindrical by 2.10 D (pâ�¤0.05). Flattening of 1.5 D more of both mean keratometry (Kmean) and steepest keratometry (Kmax) also flattened by 1.50 diopter with the combined procedure. Corneal volume decreased in Group I whereas, there was an increase by 2.89 mm in the combined procedure. Conclusion: Refractive and topographic outcomes improved post-operatively in both the groups; however, the simultaneously combined procedure provided significantly better results. The refractive outcomes in both groups were independent of gender, age and the eye involved.
