The slow loss of your vision can be a hugely depressing event. You really start to feel your age even if it starts to go when you are relatively young. Fortunately, there is an excellent chance that Lasik eye surgery can return your vision to normal.
What Is It?
Lasik eye surgery is a medical procedure in which a laser is used to fix physical problems in the eye structure. Lasik is actually an abbreviation for the medical name of the surgery which is "Laser Assisted In Situ Keratomileusis". The procedure has become the single most popular vision correction surgery currently performed in the United States.
Refractive Surgery
Lasik eye surgery is a form of refractive surgery. This type of surgery focuses on reshaping the cornea element in the eye. The cornea is a round shaped, clear tissue located at the front of the eye. The goal of the surgery is to reshape the curvature of the cornea. In doing so, the images that pass through the cornea can be refocused onto the proper area of the back of the eye where the brain can process them through the optical nerve.
Vision Problems
When we develop vision problems, we don't all develop the same type of difficulties seeing. Some of us will have problems seeing things close to us while others will have problems seeing things farther way. The wonderful thing about Lasik eye surgery is that it is able to be used to treat any vision problem that arises from an issue with the cornea. This means it is a potential solution for issues such as nearsightedness, farsightedness, astigmatism, and even presbyopia. Presbyopia refers to an age-related problem where your eyes lose the flexibility needed to change focus when looking at something close to you. Regardless, Lasik can produce excellent results when it comes to remedying these problems. The vision of the patient can be returned to 20/25 in eighty percent of the cases. This means you no longer have a need for glasses or contact lens - a happy day indeed!
The Process
The surgical process is surprisingly simple. Initially, you will go into the office to have your eyes examined as part of a consultation. From there, the physician will develop a plan for the surgical procedure and apprise you of the potential results. Once you choose to go forward with the surgery, you will return to the office at a preset time. You then simply walk back into the surgical room and take a seat. The physician will then ask you to look at some object on the far wall and tell him or her what you see. Since you have vision problems, usually you cannot see anything other than an indistinct, blurry object.
At this point, you lay down on the surgical platform. Your doctor will then numb your eyes with liquid anesthesia. They will then start to apply the laser in short bursts to the target areas of your cornea. The laser will actually remove tiny amounts of the cornea as it slowly reshapes it into the desired angle. Once the goal is reached, the doctor will repeat the process on the other eye.
The entire surgery will take between 10 and 15 minutes. You'll then be asked to sit up and look at the object on the far wall that you were unable to identify before the surgery. There will be instant gratification when you realize that you can not only see the object, but see the finest details of it. Congratulations, your vision is fixed.
For those of us who were forced to wear glasses or contact lens for years, Lasik eye surgery has been a medical miracle. The sheer joy of having clear vision again is something that simply cannot be underrated.
