One of the major drawbacks of PRK is that because the full outer layer of the cornea (epithelium) is totally removed, to reach the corneal surface, hence increasing the healing period significantly when the epiteletet must grow back.

In a Lasik operation a fine tool, named microkeratom are used to do a small incision in the cornea and to then make a ""cap"" around the eye. It also makes a little part which may act as a "hinge". Lightly raised the little lid is removed with the corneal surface displayed. The treatment with the eye laser can then be started. After completion of treatment the cap is lifted back on once again.
