LASIK stands for Laser-Assisted in Situ Keratomileusis. It is a process of permanently changing the shape of your cornea. Hence having a LASIK eye surgery can be a permanent solution to fix those vision problems caused by refractive error. In addition, this surgical process is quite painless and takes a minimal time to complete.
Keep reading this blog to know about this surgery, its benefits and other details.
LASIK eye surgery is a common procedure that helps people reduce their dependence on glasses or lenses. The results post this surgery have shown that a person’s astigmatism, near-sightedness and far-sightedness or refractive errors have reduced significantly.
You will only qualify for this surgical process if you have been wearing contact lenses or glasses for a long time. In addition, you must also have a stable vision.
There are mainly three types of vision problems that can be corrected if LASIK surgery is successfully performed.
This is caused if your eyeball is longer than normal or if the cornea curves sharply. Therefore, the light only focuses in front of the retina and blurs distant vision. If you have myopia, you will see close objects clearly but not the objects that are far away.
Hyperopia or hypermetropia is caused when your eyeball is slightly shorter or your cornea is too flat. In such cases, light focuses behind the retina. Hence this makes the vision blurry for closer objects than those located far away.
This is a condition when the cornea unevenly curves or flattens. Astigmatism results in disruption of focus, which eventually blurs the vision.
As you have got some idea about what Lasik surgery is, you are aware of the main process, which is to change the shape of your cornea.
However, let’s understand the process. It usually involves two vital steps: creating a corneal flap and reshaping the cornea. This precise method is done with a Laser and advanced tools.
Your doctor will take just 30 minutes of the operating room for this procedure. Sometimes the surgery time can vary as it depends on your eye condition and the amount of correction you require.
Since you are considering LASIK, it suggests you have certain levels of vision impairment and are looking for a permanent solution. Therefore, before the surgery, your Ophthalmologist will prescribe a general check-up. The following pointers will help you know how to prepare and what you should expect for this evaluation:
If you regularly wear contact lenses, it is suggested to stop wearing them for a while, but wear glasses before the check-up. This is because contact lenses change the shape of your cornea.
So, not allowing your cornea to understand its natural shape can impact negatively during the surgery. The consequences of not leaving contact lenses for a certain period can lead to inaccurate measurements and incorrect surgical plans, eventually resulting in poor vision.
Sharing your medical history with the doctor is essential, as the surgical process is dependent on this information. These are the following things you must share with your doctor.
While undergoing a thorough evaluation, you must inquire with your doctor regarding the following subjects.
On the day before surgery, you must stop using any kind of product on your skin. It includes creams, lotions, makeup, and perfumes. Doctors recommend not to use them before surgery because the debris from these products can cause infection.
Your doctor can also ask you to scrub your eyelashes to remove any foreign particles prior to the surgery.
Generally, during these sessions, doctors ask someone to tag along with you as they will have eye patches, and it becomes difficult to move alone. In addition, post-surgery, you will have been given medications that may blur your vision. This is why make sure to arrange transportation to and from your surgery.
Here are the steps that doctors follow for LASIK surgery.
Step 1: At the beginning of the LASIK surgery, eye-numbing drops are given.
Step 2: Your eyelids are gently held open to position a precision flap-making instrument.
Step 3: The surgeon will ask you to focus on a fixation light while they activate the instrument. A few seconds later, they will be able to fold a corneal flap that opens up the middle layer of the cornea.
Step 4: The cornea is then reshaped using an excimer laser. This reshaping again varies as per your vision. For instance -
Step 5: The corneal flap is then repositioned. The flap is held naturally in place until the surface has healed.
Recovering from LASIK is extremely fast. Most people tend to resume their daily activities within 24 hours. Apart from that, post-surgery, you will have to follow certain rules like using eye drops as prescribed and wearing sunglasses even at night to avoid rubbing your eyes.
The consequences of the surgery vary from one to another. Some of the common after-effects of LASIK surgery are as follows:

Unlike other surgical processes, LASIK is almost painless and takes 10-30 minutes, depending on the amount of correction needed. Some may fear this surgery, but you must know it is a simple and quick procedure. It will get over before you even know it.
As this process is completely regulated by lasers and there is no stitching involved, its post-operative recovery is very fast. Complications after LASIK are hardly ever noticed.
Wearing contact lenses can cause itchiness, watery eyes and other allergic reactions. This happens when there are pollutants and pollen can get trapped inside them. If you choose to have LASIK, you will eventually get relieved from such allergies.
