Tip of the Week
Advancements in technology have made it possible for surgeons to create the corneal flap necessary for vision correction surgery with the use of an infrared laser, as opposed to a mechanical blade. This improved technology has greatly improved the precision with which surgeon are able to create a flap in the cornea. With an accuracy of +/- 10 microns, the infrared laser enables the surgeon to create exact cuts which are tailored for each patient individually.
The increased precision during an all laser LASIK procedures stems from the ability to control the thickness, location and angle of the cut in the cornea to create a flap customized for each patient. During the procedure a series of microscopic bubbles are created just beneath the surface of the cornea. These bubbles are placed with great accuracy to ensure the flap adheres properly at the conclusion of the procedure.
