How does LASIK Work
The beginning of successful LASIK starts with extensive measurements and medical Evaluation. In fact, a prospective LASIK patient will spend more time visiting Dr. Cabler's office - as many as three visits total -- to recheck refractions and to undergo diagnostic testing such as topography (mapping of the cornea shape), pachymetry (measuring corneal thickness) and checking pupil size. Additionally, Dr. Cabler dilates the eyes to determine if any underlying medical condition would prevent LASIK. This extra effort is critical when one considers that the accuracy of these measurements and their interpretation by a medical doctor are directly related to how the laser is utilized during the actual surgery.
The actual laser surgery takes just a few minutes per eye. Prior to the procedure, the patient receives topical anesthesia, and if desired a mild sedative - however, the patient is awake during the procedure. The first action in the surgery suite is the cleansing of the eyelid area, then paper taping the eyelashes to prevent infection. A portable device called a speculum is positioned in the eye to prevent blinking. A suction ring is then placed on the eye, and a momentary blackness occurs. While this suction is occurring, an instrument called a microkeratome glides across the top layer of the cornea, making a thin incision - and creating a flap of tissue. The physician lifts back this flap, then proceeds to position the laser and directs the laser energy. The patient will hear a series of pulses as the laser reshapes the cornea.
The doctor then lays the flap back down, creating a bandage effect. This eliminates the pain, and no sutures are involved. Typically, the same process occurs for the second eye.
After the procedure, the patient is walked into an adjacent exam room, where clear plastic shields are positioned over the eyes to shield them so the flaps can be protected from injury.. Someone must be present to drive the patient home.
It is highly recommended that the patient rest for four hours with their eyes closed immediately after the procedure to promote healing. The shields can be removed after those four hours. The patient can then resume normal activities with exception of underwater sports. If you shower, close your eyes. The patient starts a regimen of drops four times a day after awakening.
The following morning you will come to Dr. Cabler's office for a follow-up post-operative visit. In many instances, individuals will notice a marked improvement in their vision - and should be able to see clearly without their glasses. Most patients drive themselves to their post-operative visits - and can resume work that same day.
