Summary

Keratoconus, which results in thinning of the cornea, affects mainly young patients. The causes are currently only partially known. The aim of this study is the evaluation of a keratoconus questionnaire in German. Until now this questionnaire is only in use in English.

Within the study patients will be asked to fill out a questionnaire. The questionnaire deals with issues that are influenced by keratoconus: Visual impairment and its impact on quality of life. This questionnaire (KORQ) is an already validated questionnaire in English. Within this study we would like to translate the questionnaire and validate it in German.

Within this study 50 patients will be included for the validation of the questionnaire. Based on previous studies evaluating the Keratoconus Questionnaire (KORQ) in other languages, a number of 50 patients has been shown to be sufficient for validation.

No control examination is necessary for this study.
