Publication trends in corneal transplantation: a bibliometric analysis

BACKGROUND Our aim was to demonstrate the publication trends of corneal transplantation in the last decade. METHODS All of the keratoplasty research articles, letters, case reports, reviews and meeting abstracts published between January 2006 and December 2015 indexed on the Thomson Reuters Web of Knowledge were evaluated. A bibliometric filter was used to capture keratoplasty related publications by using the key words 'keratoplasty', 'corneal transplantation' or 'keratoprosthesis' in the 'title' selection mode. RESULTS A total of 2726 publications were evaluated in the present study. Documents related to penetrating keratoplasty only have been decreased, whereas the documents related to endothelial keratoplasty were increased in the last decade. The total keratoplasty publication counts had been increased from the year 2006 to 2015. The average citation count per keratoplasty documents was 9.34. CONCLUSIONS There is a growing interest to the lamellar keratoplasty techniques especially the endothelial keratoplasty in the last decade.
