Crystallization on Intacs
Because the Lasik flap "seals but never heals," the flap no longer contributes to the structural integrity of the cornea. As a result, the intraocular pressure which helps the eye maintain its shape pushes against a much thinner wall of stromal tissue. Sometimes this results in a condition called ectasia, where the wall of the eye balloons, like a hernia. Surgeons have attempted to treat this condition with "intacs," but these metal inserts can certainly do more harm than good, and may need to be removed.
