Lasik Eye Surgery | How does this surgery help ?
March 21, 2022 by ASG Eye Hospital0
Many of us wear eyeglasses or contact lenses to see clearly or to correct our vision. But sometimes people fail to take care of our eyes. Like going off to bed with specs on, or mistakenly splashing water on the face while wearing the lens. In both cases, you are at harm. To not have such bad experiences, you can look out for a permanent solution to your visibility problem, i.e. Lasik Eye Surgery.
What is Lasik Eye Surgery?
In simple terms, Lasik surgery is undertaken to correct several eyesight conditions. A normal person can see everything. But people with nearsightedness or farsightedness cannot see the outside world’s images very clearly. It happens because outside world images don’t fall exactly on the retina, which thereby causes a refractive error. The light rays of the outside world do not get focused on the retina causing blurred images.
In a broader outlook, the outer layer of the eye is the cornea, and people’s cornea shape can be changed which leads to vision issues that call for Lasik Eye Surgery Treatment.
This surgery reshapes the cornea depending upon the vision condition that this particular treatment aims to fix. It corrects vision issues like nearsightedness & farsightedness.
The surgery doesn’t require much time. It takes nearly around 15 minutes and people remain awake during the whole procedure of the surgery. It is not painful. Right before going under the procedure, the surgeon will put numbing eye drops in both eyes. But you might experience a little pressure during the surgery.
Know the procedure of the surgery..
Firstly, a mechanical surgical tool named microkeratome or a femtosecond laser is used to make a thin & circular flap in the cornea. The Lasik Specialist then folds back this turned flap to approach the underlying cornea (or stroma).
Secondly, to bring back the cornea (corneal stroma) in shape, an excimer laser is used. This highly modernized laser tool uses a cool UV light beam to remove microscopic amounts of tissue from the cornea. The process reshapes the cornea accurately and the light now perfectly reaches the retina thereby enhancing improved and clear vision.
At last, the corneal flap is placed back in place, where it adheres to the corneal stroma without stitches.
Things to keep in mind after surgery:
After the surgery, the doctor will give you a brief post-op eye exam. Once the doctor/ eye specialist confirms that the surgery was successful, he or she will be discharged & allowed to go home.
The person cannot self drive the car or any other vehicle to home after discharge. He or she must be driven by a family member or a friend. He/ She is not allowed to drive until the doctor says after a follow-up visit. During the follow-up meets, the doctor will discuss & confirm that the vision is within the legal standard for driving.
The doctor will call after a week of the surgery to have a look at the healing process. At that visit, they will determine whether more follow-up visits are required or not.
Refrain from doing any heavy exercise for the week after surgery, as it can disturb the healing process.
Avoid wearing eye makeup for a week. When you resume, use new products to avoid any kind of infection. Doctors prescribe eye drops & artificial tears that help to speed up the healing process, fight against bacteria & infection and combat the eye from drying.
When can a person expect the results of Lasik Eye Surgery?
The person undergoing the eye surgery can immediately see the result. He or she begins to see things from a distance that they were not able to see before. While a person may feel a little irritation & haziness initially, it will be stabilized and day by day it gets improved after surgery. It is common for eyes to feel a little powdery or dusty or sensitive to light.
Doctors always ask the patients to keep their eyes closed for a few hours. After at least 6-7 hours, patients feel comparably comfortable with their vision. In some cases, patients may feel comfortable the very next day of surgery. However, this depends on the intensity of the patient’s eyesight before the eye surgery.
Every surgery has some risks involved. With this surgery, you may struggle with the Dry eyes which can be handled through lubricating eye drops.
