LASIK surgery is performed by an ophthalmologist who uses a femtosecond laser or a microkeratome to create a corneal flap to expose the corneal stroma and then an excimer laser to reshape the corneal stroma in order to improve visual acuity. [2] [3] LASIK is very similar to another surgical corrective procedure, photorefractive keratectomy (PRK ...
During the procedure, the epithelium is displaced using a diluted alcohol solution. [4] PRK has advantages over LASIK in that it avoids added complications associated with the flap created during surgery. The procedure may also reduce the chances of dry eye symptoms after surgery.

The non-dominant eye is covered and the dominant eye is opened and kept open by a speculum, the corneal flap is lifted and the laser correction is done – an ultra thin flap can be created for treatment of ...
Barraquer's surgery required the creation of a free flap, which meant the cornea was completely cut through. In 1991, Ioannis Pallikaris introduced the concept of a corneal hinge, which kept the cornea flap attached and helped with the healing process. [10] During the same year, the motorized microkeratome was released.
