[Posterior polymorphous dystrophy and LASIK].
OBJECTIVE
A 50-year-old hyperopic woman requested information about refractive surgery. Vesicle and band lesions at Descemet's membrane and endothelium were suggestive of posterior polymorphous dystrophy (PPD). Lower than normal endothelial cell densities were detected. A corneal refractive procedure was not recommended in this case.


CONCLUSIONS
The presence of vesicles and bands at Descemet's membrane and endothelium is suggestive of PPD. Specular microscopy is mandatory in such patients, although corneal decompensation is not evident. A low endothelial cell count may be a contraindication for a hyperopic LASIK procedure in cases of PPD because of the possible risk of corneal decompensation.
