| Popis: | To describe characteristic histopathologic markers in deep anterior lamellar keratoplasty (DALK) using pneumatic dissection: Anwar "big-bubble" technique.Case reports. Deep stromal buttons from 2 patients with keratoconus who had undergone DALK surgery using the "big-bubble" technique were examined by light microscopy.The histopathology of excised corneal buttons demonstrated multiple intrastromal spaces consistent with air bubbles. Apical stromal thinning seen clinically was not as readily appreciated on histopathology.Pneumatic dissection in DALK produces diffuse intrastromal air bubbles that may mask the corneal thinning that usually characterizes keratoconus histopathologically. This is a characteristic finding of which ocular pathologists and corneal surgeons should be aware. |
