LASEK surgery is a combination of PRK and LASIK techniques. In this procedure, instead of cutting a flap on the cornea or removing the first slice of the cornea with a mechanical device, the epithelium is removed with the help of alcohol (18%). This procedure is oriented to help patients with thin cornea that need to be corrected.
First of all, doctor apply local anesthesia into the eye, then introduce a medical device called eye lids speculum in order to hold the eye lids of the patient while he/she is performing, after that, the doctor apply the Janach trephine instrument "ring" to control for 30 to 40 seconds an small solution of (18% alcohol) over the surface of the cornea, then He/She pushed the loosened epithelial flap toward the hinge, then he/she continues by irrigated the cornea in order to remove all the alcohol solution that applied previously for 30 to 40 sec, then he/she carried out the corneal tissue and start drying the cornea in order to proceed with the Excimer Laser treatment. Finally the surgeon introduce a bandage contact lens to the patient in order to prevent any touch of foreign body when the cornea is healing.
