Undergoing laser eye treatment is a permanent solution to any eye condition. It is a quick, painless, and hassle-free operation but still worries patients since they are not aware of how this type of eye surgery is performed. Correcting the eyesight through laser is a scary and frightening experience but knowing how laser eye treatment is performed should change the minds of skeptics and non-believers alike.

The first step in performing laser eye treatment involves prepping up the patient’s eye through a local anesthetic that will be dropped on the eyes to guarantee a pain-free operation. This will result to a mild stinging sensation that will last for about 10 seconds only after which, a slight irritation will occur. This irritation should be expected to last throughout the entire procedure. The local anesthetic will take about 30 minutes to work; however, it will last for the entire duration of the surgery, sometimes even lasting for hours after the procedure has taken place.

A clamp is then used to secure the eyelids apart and this will make blinking difficult for the patient. This is done to prevent the eyelids from getting injured during the actual ablation process. Because blinking becomes nearly impossible at this point, lubricants will regularly be applied on the eyes.

For standard laser eye surgery, which is lasik, a flap is created on the uppermost layer of the cornea using an intralase laser. This flap will cling to the front of the eye and then flipped back to exhibit the cornea below. Using an excimer laser, the stromal layer of the cornea will be vaporized according to the curvature of choice. This process will only take about 10 seconds and the patient will have to look at a blinking light which will trigger the excimer laser when to blast the eye. This eye tracking device will guarantee the accuracy and precision of the process.

After this step, the ophthalmologist will carefully replace the flap over the eye, making sure that no debris will get trapped under the flap which has to be placed on the center of the eye. This part of the laser eye treatment is done one eye at the time and does not require any stitches at all.

Post-operation, a brief follow-up inspection is done 20 minutes after the surgery which involves placing a plastic transparent shield over the eye so as to prevent the patient from rubbing the eyes as well as foreign objects from entering. This should only be done for one day, after which can be disposed of the following day.

Taking up only 90 minutes of a patient’s time, laser eye treatment requires only a very small amount of time in exchange of a lifetime of improved visual acuity.
