Purpose To describe the histopathologic changes in human ectasic corneas, induced after implantation of intracorneal ring segments. Methods Ten eyes (7 advanced keratoconus, 2 post‐lasik ectasia and 1 marginal pellucid degeneration) recieved corneal implants (Ferrara‐Keraring like) for treatment. Due to a poor refractive out‐come they had penetrating keratoplasty. Results Conventional histology on all specimens after hematein‐eosin stain, showed no inflammation signs and hypoplasia of the corneal epithelium immediately surrounding the channel. Conclusion Histopathologic changes seem to be complety reversible after implant removal. Longer follow‐up is necessary to determine whether they accelerate corneal thinning or inflammation response.
