Transepithelial CXL With or Without Intrastromal Corneal Ring Segment Implantation With More Than 1-Year Follow-up
Narrative Responses:
Purpose
To evaluate the efficacy of transepithelial collagen crosslinking (CXL) with or without intrastromal corneal ring segment implantation (ICRS).
Methods
This retrospective study comprised consecutive patients with progressive keratoconus having transepithelial CXL with and without ICRS implantation on the same day or on different day and who had follow-up of 1 year or more. The main outcome measures included uncorrected distance visual acuity, corrected distance visual acuity, mean refraction spherical equivalent, keratometry.
Results
136 eyes of 84 patients were included in the study. More than 1 year after transepithelial collagen crosslinking (CXL) with or without intrastromal corneal ring segment implantation (ICRS), there was a stabilization of uncorrected distance visual acuity, corrected distance visual acuity, and the mean and steep K values. No patient lost CDVA lines.
Conclusion
Transepithelial collagen crosslinking (CXL) with or without intrastromal corneal ring segment implantation seems to be a safe, effective treatment for stabilization of the progression of keratoconus.
