Refractive surgery has been used globally since the 1970s. In 1987, refractive laser surgery opened up entirely new possibilities for the correction of visual problems. Vision problems including myopia or nearsightedness, hyperopia or farsightedness, and astigmatism can be cured by eye surgery. Gone are the days, when the eye surgery was risky and imprecise. New machines like WaveLight help in giving a highly precise eye surgery. The refractive surgery can eliminate these vision defects and provide clear vision. People wearing glasses or contact lens face some changes to their normal active lifestyle. Some people complain that they cannot enjoy sports and face problem while riding vehicles in the night. Today, people prefer to have vision correction eye surgery than wearing a glasses or contact lens.

Procedure:

Most of the eye sight abnormalities occur because of shape of the cornea. If the shape of the cornea is adjusted accordingly, the eye sight can be recovered. Lasik eye surgery is a procedure where the patient can walk into the surgical theater and walk out without much inconvenience. In most of the surgical cases, the patient experiences little pain. First the eyes on which the surgery is to be performed is anesthetized with special anesthetic drops. The surgeon has an ink marker to mark the area over the corneal flap to be cut. A precise cut is made on cornea, using a device called microkeratome. The surgeon carefully puts the flap back. The corneal flap is then lifted up to allow the laser beam to pass without any obstruction. The laser beam is applied to the surface of the cornea. The excimer laser removes the tiny bits of tissue from the cornea to reshape it. The flap is replaced over the treated area. After the surgery, it is important to follow the doctors instruction. The doctor might advise the patient to take rest or go home to relax for few hours.

Benefits of Laser-In-Situ Keratomileusis or Laser Surgery:

• Being more accurate and precise, lasik surgery is safe technique.
• It is quick procedure taking just 30 minutes for complete surgery with preoperative preparations.
• After the operation, the patient can walk out of the theatre.
• The antibiotic steroid drops are given just for few days and gives quick visual recovery with no patching of the eyes required.
• The possibility of getting scarring in the eyes during the operation is minimal.
• The laser beam reshapes the cornea giving clear vision.
