Can corneal dystrophy be healed?
The progression of corneal dystrophy doesn’t have a reliable timeline; it can range from months to decades. Corneal dystrophy is an inherited condition, which means prevention is a mystery. The good news is that this condition is treatable. There are a number of promising medications, topical and oral, that may offset the effects of corneal dystrophy. There are even custom-designed contact lenses that improve the quality of vision while helping the eyes to heal.
When should you treat EBMD with PTK?
Successful treatment of EBMD is predicated upon optimizing conditions necessary for the formation of stable epithelial basement membrane adhesion complexes throughout the entire cornea, preferably before the development of vision-compromising morphological abnormalities in the visual axis.

How to diagnose corneal dystrophy?
A routine eye examination can detect the development of corneal dystrophy. A full clinical examination is the best way to get an accurate diagnosis. This process will entail a patient history, especially determining if the patient has a family history of corneal dystrophy, and testing, like a slit lamp examination. With a slit lamp exam, a special microscope (a slit lamp) gives a doctor a high degree of magnification to study the buildup of particles and discover whether they are affecting corneal functions.
