NCT01164358

Brief Summary

This study is a prospective, open, not randomized, unilateral multicenter eye study consisting of two study arms to observe the long term satisfaction of patients after an INTRACOR treatment. The satisfaction is determined with the help of the patient perception and the subjective / objective diagnostic data. The hypothesis of the study is that patients after an INTRACOR treatment are satisfied in the long term.

If two out of these three questions are answered with "yes" then it can be assumed that the patient is satisfied.

    36 months

Secondary Outcomes (1)

  • Determination if there is any correlation between patient satisfaction and subjective/objective diagnostic data.

    36 months
