| Measure | Description | Time Frame |
|---|---|---|
| An overview about absolute numbers of corneal transplantation in Germany. | A questionnaire about absolute numbers of corneal transplantation per year was sent to the 111 ophthalmological departments in Germany performing corneal transplantation. Data has been and is collected annually since 2001. | 01/01/2001 to 31/12/2031 |
| An overview about trends in the various types of corneal transplantation in Germany. | The questionnaire also records the types of corneal transplantation (i.e. penetrating keratoplasty, deep anterior lamellar keratoplasty, Descemet membrane endothelial keratoplasty (DMEK) and Descemet's stripping automated endothelial keratoplasty DSAEK) allowing a discussion of trends in corneal transplantation. Data has been and is collected annually since 2001. | 01/01/2001 to 31/12/2031 |
| An overview about indications for corneal transplantation in Germany. | The questionnaire also records the indications for corneal transplantation (e.g. Fuchs' endothelial corneal dystrophy, pseudophakic corneal decompensation, repeated keratoplasty after graft failure, keratoconus and corneal scarring). Data has been and is collected annually since 2001. | 01/01/2001 to 31/12/2031 |
