Gliederung
Text
Refractive complications of corneal surgery after previous corneal procedures (LASIK, PRK, RK, DALK, PK etc.) will be discussed. Patient complaints and diagnostic testing must lead to a specific diagnosis in order to best choose the therapeutic course of action (Wavefront-guided, Topography-guided, Trans-epithelial PTK or others). Subjective and objective tests will be discussed in the context of obtaining a diagnosis in the various types of complication (small optical zone, decentration, irregular astigmatism, irregularly irregular surfaces etc.). The impact of epithelial remodeling compensating for stromal surface irregularities will be described, with examples of how this can lead to a mis-diagnosis by wavefront or topography.
