When do you need a cornea transplant if you have lattice dystrophy?
If your disease is more severe, you may need a corneal transplant. Lattice dystrophy usually begins in childhood. It causes material to build up on the cornea in a lattice (grid) pattern. As the material builds up, it can cause vision problems.
