TitelEarly clinical outcomes after implantation of corneal allograft ring segments (CAIRS) for the treatment of keratoconus
DoelTo evaluate the early visual and topographic outcomes of corneal allograft ring segment implantation (CAIRS) using KeraNatural™ for the treatment of keratoconus.
MethodesThis retrospective case series included ten eyes of ten patients with a 3-month follow-up after CAIRS implantation. All eyes were treated using sterile allograft corneal ring segments (KeraNatural™, Lions VisionGift, Portland, OR, USA). Corneal tunnels were created according to the Istanbul nomogram. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive cylinder, and keratometric values (Kmean and Kmax) were evaluated preoperatively and at 3 months postoperatively.
ResultatenAt 3 months postoperatively, visual acuity and corneal topographic parameters improved. Mean UDVA (decimal) improved from 0.17 ± 0.23 to 0.56 ± 0.24 postoperatively. Mean CDVA improved from 0.38 ± 0.27 to 0.73 ± 0.18. Mean Kmean decreased from 50.3 ± 3.6D to 46.5 ± 3.4D, while mean Kmax decreased from 64.5 ± 9.3D to 56.1 ± 6.3D. Mean refractive cylinder improved from 4.2D to 1.9D. No intra- or post-operative complications were observed during the follow-up period.
ConclusieEarly results after CAIRS implantation using KeraNatural™ demonstrate encouraging improvements in visual acuity and corneal regularization in keratoconus patients. These findings suggest that allograft corneal ring segments may represent a promising minimally invasive treatment option for selected keratoconus cases.
