OBJECTIVE To develop a laboratory model to study intracorneal keratoprosthesis implantation. METHODS A combination microkeratome and artificial anterior chamber system was used to create a hinged lamellar keratectomy on 13 human corneas. After reflecting the flap, the posterior stroma was trephined at either 2.5 or 3.0 mm. A model keratoprosthesis was positioned in the bed. The flap was sutur...
Intracorneal microinjections of foreign protein, conjugated to 1-131 as radioactive tracer, ivere diminished initially to an average of 71 per cent of the amount injected. After the fint day as little as 14 per cent of the intended inoculum remained. However, this did not constitute true diffusion but early leakage of protein through the needle track. The remainder was slowly lost by diffusion ...
PURPOSE To analyze and compare changes to the anterior and posterior corneal surfaces after Ferrara intracorneal ring segment (ICRS) (AJL, Boecillo, Spain) implantation and to correlate those changes with visual outcomes. METHODS This retrospective case series study comprised consecutive patients with keratoconus implanted with the Ferrara ICRS. Computed tomography scans of the two corneal su...
