47-year-old man with type II granular corneal dystrophy (Avellino) manifested after undergoing LASIK vision correction. Avellino dystrophy is known to blossom after LASIK. For this reason, it is the practice in some Asian countries with high prevalence of Avellino (most prominently Korea where prevalence approaches 1/1000) to perform routine genetic testing to rule out the TGF beta 1 mutation in all candidates for laser vision correction. For more information on the anterior stromal corneal dystrophies see the following case: http://webeye.ophth.uiowa.edu/eyeforum/cases/43-Corneal-Stromal-Dystrophies.htm
