Definition

A free cap is a complication of LASIK in which instead of a flap with hinge, there is a complete resection of the flap. Usually this occurs due to unintended complete section or loss of suction.

Immunohistochemistry

As free caps are caused by mechanical factors (microkeratomes), no immunohistochemical process is involved.

Differential Diagnosis

Every other LASIK complication includes incomplete cuts, buttonholing, flap perforation, epithelial defects, wound dehiscence, irregular ablation, flap wrinkling, or slicing.
