Unlike conventional surgery the process of LASIK surgery is less time consuming, very effective and painless. It is a procedure that is often performed around the world by eye specialists without any anxiety on the part of the patient. A excimer laser beam is used to reshape the cornea and correct vision.
A Step By Step Account of the LASIK Procedure
First Step – Preparation for the procedure using an anesthetic
A patient is seated comfortably and then drops of anesthetic are applied into the eyes to numb any sort of pain or discomfort.
Second Step – Incision in the cornea
An instrument called a microkeratome is used to make an incision in the cornea and create a flap that is lifted to reveal the corneal tissue.
Third Step – Shaping the surface of the cornea
Using an excimer laser, the cornea is reshaped. The doctor may make the surface of the cornea smooth or change the overall curve of the cornea to improve near sightedness, farsightedness or astigmatism in the patient’s eye.
Fourth Step – Flap replacement
The flap is then replaced over the cornea to facilitate healing and the patient’s eyes are then cleaned. The patient is then kept under observation and then allowed to leave after two hours.
Post Surgery Recuperation
The goal here is for the patient to have a painless, complication-free and quick recovery. After the initial discomfort disappears, the patient is required to take the prescribed antibiotics and anti-inflammatory medications. Certain precautions need to be taken by the patient at home to facilitate quick healing. He or she must not rub their eyes. They must use sunglasses while going out. They also must use eye shields at night. Strenuous physical activity is also not allowed during the recovery process. Swimming pools, bathtubs and Jacuzzis must be avoided to keep the water from entering the eye and causing damage.
The vision of the treated patient may take a few weeks to completely return to normal. A patient can undergo the LASIK procedure for both eyes at the same time. It is possible to return to work and even drive a vehicle after 48 hours but night time driving may be a little difficult for some time. However care must be taken to avoid dusty and dirty environments at all times.
