Aloha RobertHunter,
The human body is an incredible "righting" machine. In his classes, Chunyi talks about the eyes being a part of the liver system. With this, taking care of and strengthenng the liver system's energy is a good place to start. A person could use the sword finger exercise from the level one course to focus on changing the energy of the scar tisssue into healthy, healed tissue. Excess energy out-healing energy in.
Much Love,
Shawn
