Understanding LASIK Surgery

LASIK surgery is a popular procedure currently being used to help people correct their vision problems. The refractive surgical procedure involve the use of special lasers capable of changing the shape of the cornea in the eye to improve eyesight by correcting vision problems such as far-sightedness, near-sightedness and astigmatism. The advantage of this procedure is that it enables patients to require less time to recover and feel less pain during surgery.

Basic Pre-Operative Procedure

The LASIK procedure requires several necessary preparations prior to the actual surgery. Prior to the actual surgery, patients wearing contact lenses are instructed not to use them for a period ranging from 5 to 21 days for those using soft lenses to as long as six weeks or more for those using hard contact lenses.

Several tests and assessments are also being made regarding the characteristics of the patient’s cornea to help determine the scope of the eye problem and the areas of the corneal tissue that might require removal during the operation. Doctors also look for other possible eye diseases and conditions that might need to be treated before the actual procedure. Patients are also given antibiotics to take beforehand in order to minimize the risk of eye infection during the actual surgery.

Actual Operation

LASIK surgery is considered as an ambulatory procedure. This means that patients come into the clinic for surgery and then are released after the procedure is done. The patient is usually awake the whole time and usually takes less than five minutes. Despite being a relatively quick procedure, LASIK surgery is a sensitive operation that requires a surgeon with considerable experience and skill.

The operation involves the surgeon cutting into a certain area of the cornea using a special laser in order to create a flap. Once this flap is turned over and expose the corneal tissues, the doctor uses the laser light pulses to reshape the cornea according to prior evaluation and tests for corrective vision. After that, the flap is then placed back on the cornea. After the procedure, the patient is allowed to rest for a while before being sent home to recuperate. Most doctors advise a day or two of rest and avoiding strenuous activity during that time to avoid possible eye trauma that may affect proper healing.
