Have you ever been annoyed with the fact that you need glasses or contact lenses to see the world clearly?
Did you yearn for a 20/20 vision?
Well, then you might have already heard about the corrective procedure for it, commonly known as the Lasik surgery.
LASIK (Laser-Assisted in Situ Keratomileusis) surgery, which is also known as Laser Eye Surgery or Laser Eye Correction is a type of refractive eye surgery to reduce or completely eliminate the usage of spectacles or contact lenses.
The procedure utilizes a maser to modify or replace the cornea in the eye to enhance the vision. A maser is a device that produces electromagnetic waves by amplifying stimulated emissions.
Lasik surgery is a possible corrective option for vision issues like nearsightedness, farsightedness, and even astigmatism, a condition where there is an error in the shape of the cornea.
Who can opt for it?
To be eligible for Lasik surgery you need to be at least 18 years old. Below are some other requirements to be eligible for it.
- The person must not have eye disorders like progressive vision deterioration, glaucoma, cataract, and others.
- Pregnant women or nursing mothers cannot undergo a Lasik procedure.
- You must be healthy and devoid of underlying health conditions like diabetes, hypertension, heart disease, or a weak immune system as it plays a major role in healing your eye after the procedure.
- You must have a stable vision for a considerable time before you can opt for the procedure.
Advantages of Lasik surgery
In addition to the obvious improvement in your vision, there are a few other benefits of having Lasik surgery.
- It has as high as 96% chances of acquiring the desired vision.
- It is an almost painless procedure, thanks to the numbing drops used before the process.
- The healing time is as less as a day.
- Reduces or completely eliminates your dependency on glasses or contact lenses.
- Its results are long-lasting, with a majority of it being permanent.
- It is a safe outpatient procedure that usually takes just 20 minutes.
Risks of Lasik surgery
With the advancement of technology, the Lasik procedure has come a long way in ensuring the safety of the patient. However, it does have small and rare complications attached to it.
Dry eyes: It is a complication where your eyes might dry out consistently for the first 6 months after the procedure. Your doctor may suggest eye drops to keep them lubricated or may even suggest another procedure to prevent your eyes from drying out.
Undercorrections or overcorrections: it is a condition when either less or more tissue of your eye is removed during the procedure. While undercorrections will require another procedure after a gap of a year, it is tougher to rectify overcorrections.
Glare: You may notice glares in your eyes or halos under bright lighting conditions and at night.
Uneven tissue removal: When the tissue of your eyes is unevenly removed, you may require another corrective procedure or the use of glasses.
Regression or vision loss: While these are pretty rare scenarios, there is a possibility for you to go back to your older vision or notice an unexpected change in your vision.
What to expect during the procedure?
Your Lasik procedure will begin once your doctor certifies you fit for it.
At the time of the procedure, you will be made to lie on your back and an instrument will be used to keep your eyelids open.
Then a mechanical surgical tool called maser will be used to cut the outer layer of your cornea to create a flap and expose the inner cornea.
This inner cornea or the corneal stroma will be reshaped with the help of a specialized laser to accurately allow light to focus on your retina, and eventually provide you a clearer vision.
The cut flap will then be laid back and does not require stitches as it will heal on its own.
The whole procedure sounds scary, right? Well, if it helps, a majority of you will not feel any pain as you will be given specific eye drops to numb that area.
What to expect after the surgery
Soon after the procedure you may feel a bit of a burning sensation and blurry vision, however, do not panick, it is quite normal. This will subside soon.
Your surgeon may ask you to rest for a while and then will let you go home after a quick examination of your eye.
You may need to visit him in a day or two to confirm your recovery and vision.
You may also be asked to wear shades for a few hours or even days to protect your eyes from the bright lights.
