Abstract: We described a modified allogeneic intrastromal lenticule implantation technique for the management of keratoconus and pellucid marginal degeneration.
Methods: Patients with advanced corneal ectasia already candidates for corneal transplantation were enrolled. An allogenic corneal lenticule was inserted into the recipient corneal stromal pocket, created by femtosecond laser. In 3 cases estimated refractive error of recipient's eyes were corrected using an Eximer laser.all patients received corneal crosslinking. This method named FASK ± EDK “Femtosecnd Laser-Assisted Alogenic Stromal Keratoplasty With and Without Excimer Laser-Assisted Donor Keratomileusis” .
Results: Graft edema decreased gradually over weeks but interface wrinkling and graft folds were observed after months of follow up and three of five patients eventually underwent keratoplasty. No other complications were recorded. Average keratometry and myopia decreased when EDK performed.
Conclusion: These results provide information for the design of future clinical studies on allogenic intra stromal rings, paracentral segments or lenticules with thinner center.
