Descemetic and Predescemetic DALK in Keratoconus Patients: A Clinical and Confocal Perspective Study

Figure 4

In vivo confocal microscopic image of a predescemetic (PD-DALK) interface 1 month after operation. A hyperreflective nonhomogeneous layer characterized by discontinuity in the deep stromal extracellular architecture was generally observed. The predescemetic interface appeared generally devoid of keratocyte cells and presented a variable degree of tissue oedema and hyperreflective extracellular matrix irregularities.
