Posterior Polymorphous Corneal Dystrophy (PPCD) is to an absolute contraindication to having LASIK. However, suitability for LASIK does depend on the severity of the PPCD. PPCD can be associated with low endothelial cell counts, corneal edema (swelling) and/or glaucoma.
These potential complications of PPCD need to be assessed by your surgeon prior to any consideration for LASIK surgery.
