LASEK and LASIK; when you say them they sound very similar. However, there are many differences between these types of laser eye surgeries.

With LASEK surgery, a medicinal alcohol is used during the procedure to treat the top layer of cornea cells for about 30 seconds. LASIK does not use a technique involving alcohol. LASEK uses a butterfly or superior hinge technique when making the flap and LASEK requires a soft contact lens as a bandage after surgery. LASIK requires no stitches or bandages for healing.
