Acrylic Corneal Implant in Keratoplasty*

Keratoprosthesis: A Review of Recent Advances in the Field

“…During the 19th century there were scattered surgeons who attempted to follow on Quengsy’s footsteps, but with equally disastrous outcomes (endophthalmitis, extrusion, and loss of the eye). Thus, it was not until the 1950’s with the introduction of new materials, such as transparent non-toxic plastics, that some measure of success began to be reported [ 4 , 5 , 6 , 7 ]. The good results of these new designs has to be also attributed to the discovery of antibiotics and steroids, which improved the postoperative management significantly.…”

Keratoprosthesis with retrocorneal fixation: preliminary results in dogs with corneal blindness

“…For such patients, an alternative mode of treatment has been the surgical application of an artificial cornea, or keratoprosthesis, to provide a small optical window for clear vision 5 . Over the last 20 years, Dohlman, Strampelli and Cardona keratoprosthesis have become the most familiar models used in human ophthalmology but as their surgical procedures required different stages and were associated with a significant rate of both early and late complications, recent experimental and clinical efforts have centered on improving keratoprosthesis safety and long‐term efficacy through material selection and device design 5–14 . As such, a keratoprosthesis made of two lightweight elements and designed to be maintained to the posterior face of the cornea by the intraocular pressure (PCL5 ® , Corneal S.A., Paris, France) has been conceived in an attempt to simplify the surgical procedure and increase the biocompatibility between the prosthesis and surrounding cornea 15 .…”
