[Use of keratoprosthesis type "champagne cork"--case report]

Kerathoprosthesis application is limited to strictly definite indications such as: after a severe corneal scald, after repeated graft rejections or temporarily just before the intricate eye operation to expose the posterior segment. Considerable progress in this province has been observed since PMMA were introduced. Recently a new successful method of "champagne cork" kerathoprosthesis, described firstly by Worst, has been reported. It is designed as a reverse cone and in comparison with other models provides significantly wider range of vision and simultaneuosly better visibility of fundus, which are the main advantages of this prosthesis. In our case this pattern of prosthesis was implanted in general anaesthesis and 24 hours after operation the visual acquity was 3/50. The insight into fundus was too blurred to assess fundus details. After 48 hours the haemorrhage to corpus vitreum appeared and after 3 months without clot absorption the decision was made to extract it by pars plana vitrectomy. In local anaesthesis the operation was performed with 3 typical entrance incisions, and clots that formed non-transparent membrane on the cone together with involved corpus vitreum were removed. After 24 hours visual acquity was 5/50 and corpus vitreum and retina could be assessed through an anterior segment. It seems that this type of kerathoprosthesis should be widely recommended.
