The cost will be differ depending on the clinic and where you live.
In this blog, we will cover what LASIK and SMILE are, how they work, key differences, benefits, costs, recovery, risks, and who is the right candidate for each.
What Is LASIK Eye Surgery?
LASIK eye surgery is a laser surgery by reshaping the surface of your eye, the cornea. That helps you see clearly without needing glasses or contact lenses and it helps your eye focus properly on the retina. The retina is where clear vision really begins.
People choose LASIK eye surgery because it makes things easier. For example, driving and working on screens become easier. It also makes it easier to wake up and see the clock. LASIK eye surgery is a fix for vision. Many adults prefer LASIK eye surgery once their eye power has stopped changing at least for a year. The procedure is also fast and mostly painless. You can see results quickly within a day or two.
How LASIK Works Step-by-Step
• Firstly you will go through a detailed eye check where the doctor maps your eye and confirms the LASIK is right for you or not.
• On the day of the surgery the doctor uses numbing drops. so you do not feel pain, and slight pressure for a few seconds.
• Then the doctor creates a flap on the cornea and gently lifts it. This is like opening a page.
• Next a precise laser reshapes the cornea based on your vision needs and this part takes less than a minute.
• Finally the flap is placed back. It settles naturally without stitches. Your vision starts improving after.
LASIK Procedure Timeline
• Before surgery, around 1 to 4 weeks, you complete eye tests and stop wearing contact lenses so your eye shape settles properly.
• On the procedure day, the visit takes about 30 to 60 minutes. Most of it is spent on preparation and the actual laser work is just a few minutes per eye.
• In the first 24 hours your vision gets better. But it may feel slightly blurry or watery.
• Within a few weeks, your vision becomes stable. Then you can return to your daily life routine without much difficulty.
What Is SMILE Eye Surgery?
SMILE eye surgery is a modern laser vision procedure by correcting your eyesight without creating a flap on the eye surface. Instead the doctor makes a tiny cut to take out a piece of tissue from the cornea. This helps the cornea get the shape so that light can focus on the retina. That is where you get vision.
People choose SMILE because it is easy on the eye and it makes your eye less dry compared to older methods, and recovery feels smoother for many and it is also useful for people with active lifestyles, like gym or sports, where flap-related issues are not ideal and at the same timeThe procedure is quick, mostly painless, and vision improves within a short time, often by the next day.
How SMILE Works Step-by-Step
• Firstly you will go through a detailed eye check where the doctor will measure your eye shape and confirm whether the LASIK is right for you or not.
• On the day of surgery they put numbing drops on your eye. So you do not feel pain, and slight pressure for a few seconds.
• Then a laser creates a small piece of tissue inside your cornea along with a tiny opening and no flap is made here.
• Next the doctor removes that small piece of tissue through the opening, which helps your vision get better.
• Finally your eye heals on its own without any stitches. You start to see soon after.
SMILE Procedure Timeline
• Before surgery, around 1 to 2 weeks, you complete eye tests and stop using contact lenses.
• On the procedure day, the visit takes around 30 to 60 minutes but the laser part takes only a few minutes.
• Around 24 to 48 hours you start to see but things might look fuzzy at first.
• It takes a week for your vision to become stable and then you can go back to your normal daily routine easily.
LASIK vs SMILE: Key Differences
| Feature | LASIK | SMILE |
|---|---|---|
| Basic Idea | Uses two lasers and creates a thin flap on the eye surface | Uses one laser and works through a very small opening, no flap |

| Dry Eye Chances | Slightly higher chance of dryness after surgery | Usually less dryness, feels more comfortable for many people |
| Eye Strength After | Flap area heals but slightly affects surface strength | Eye structure stays stronger since no flap is created |
| Touch Up Option | Easier to do small corrections later if needed | Touch ups are possible but not as simple as LASIK |

Benefits of LASIK Over SMILE
• LASIK has been used for many years, and because of that it is more widely available and there is a lot of information about it.
• Most of the eye surgeons are trained to do LASIK, so access is easier in many places.
• It offers more flexibility in treatment, especially when your vision problem is not simple.
• It also allows easy touch ups later, which means the same flap can be lifted again if needed.

Benefits of SMILE Over LASIK
• SMILE is a new method. It is designed to be easier on the eye, so that the eyes do not get disturbed much during the procedure.
• It does not create a flap so the eye structure stays more natural and stable after surgery.
• Because the opening is small the eye does not get as stressed on the eye tissues.
• Some people are not suitable candidates for LASIK with dry eyes or thin corneas are suitable for SMILE.
• It is also preferred by people with active lifestyles and where eyes are safer in daily routine.
Lower Dry Eye Risk
• First thing SMILE reduces dry eye issues compared to LASIK.
• It affects few nerves so the eyes can still make tears naturally.
• Many people feel less dryness and irritation after the surgery.
• The eyes feel comfortable again quickly usually in a few weeks.
• This makes SMILE a better choice if you already have mild dry eyes or feel discomfort with contact lenses.

LASIK Qualifications
• First qualification is people should be 18 years or older and have stable vision for at least one year.
• LASIK can treat nearsightedness, farsightedness, and higher levels of astigmatism.
