Risk: Refractive surgery typically works by thinning the cornea. If the cornea is too thin, refractive surgery may thin it to levels that make it problematic. The ranges are variable and depend on the measurements specific to your eyes. But in general, the risk of corneal ectasia exists after any surgery that thins the cornea. There are many solutions to this scenario that can be explored if needed.
