Intrastromal corneal rings and corneal collagen crosslinking for progressive keratoconus: Comparison of 2 sequences
Purpose To compare 2 sequences of combined intrastromal corneal ring segment (ICRS) implantation and corneal collagen crosslinking (CXL) in progressive keratoconus. Methods In this retrospective study, CXL was followed by ICRS implantation (group A) or ICRS implantation was followed by CXL (group B)...

Summary: | Purpose To compare 2 sequences of combined intrastromal corneal ring segment (ICRS) implantation and corneal collagen crosslinking (CXL) in progressive keratoconus.
Methods In this retrospective study, CXL was followed by ICRS implantation (group A) or ICRS implantation was followed by CXL (group B). Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, spherical equivalent (SE), manifest cylinder and mean keratometry (K) were compared preoperatively and postoperatively.
Results 17 eyes of 10 patients with progressive keratoconus were included in this study, 11 eyes in group A and 6 in group B. The mean interval between treatments was 4.3+/‐2.9 months in group A and 5+/‐4.4 months in group B. The mean age is 27.6 years in group A and 28.4 years in group B. The 2 groups are equivalent preoperatively. The mean UDVA and CDVA improved in both groups (UDVA:0.50+/‐0.22 to 0.60+/‐0.20, group A, and 0.28+/‐0.19 to 0.62+/‐0.22(p |
