Prevalence of transforming growth factor β-induced gene corneal dystrophies in Chinese refractive surgery candidates

The prevalence of the TGF β-induced gene corneal dystrophies in Chinese refractive surgery candidates was estimated to be approximately 0.24%. Genetic testing is recommended to identify and exclude from candidacy all individuals with a TGF β-induced gene dystrophy before elective keratorefractive surgery to avoid causing accelerated postoperative dystrophic deposition.
