When patients present for laser vision correction info, what is very often the first question after “does it hurt?” is, “What is the difference between traditional LASIK and this new blade-free version?
It is a fair question. With bladeless LASIK, we see a change in how we do refractive surgery. Instead of a mechanical blade, we have a precise laser which at every step of the process makes the procedure safer and more controlled for most patients.
What Is Bladeless LASIK Surgery?
In the procedure known as Bladeless LASIK, which is also referred to as Femto or femtosecond laser-assisted LASIK, we see a two-step laser process that corrects issues like myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism.In what we term as traditional LASIK, a mechanical device named the microkeratome blade is used to make a thin flap on the cornea which in turn is reshaped by the laser. In bladeless LASIK, the flaps are made using a femtosecond laser, a very fast laser that works in trillions of a second instead of a blade.
Once the flaps are made, a second laser, called an excimer laser, is used to reshape the corneal tissue under the flaps which in turn corrects your refractive error. For the great majority of people, the result is clearer vision free of glasses or contact lenses.
Bladeless LASIK vs Blade LASIK: What Is Actually Different?
Patients often hear both options mentioned and are unsure which matters for them. The core difference comes down to how the corneal flap is created at the very start of the procedure.
| Feature | Bladeless LASIK surgery | Traditional blade LASIK |
| Flap creation method | A femtosecond laser no physical blade touches the eye. | Microkeratome a mechanical blade creates the flap. |
| Flap precision | More uniform thickness and edge consistency throughout. | Slightly more variable depending on blade quality and individual corneal shape. |
| Risk of flap complications | Lower laser-created flaps tend to be more predictable and easier to reposition. | Slightly higher risk of irregular flap edges or buttonhole flaps. |
| Suitable for thin corneas | Often a better option for borderline thin corneas where blade control matters more. | May be less predictable on corneas with unusual curvature. |
| Procedure feel | Both are done under topical (eye drop) anaesthesia; you remain awake but feel no pain. | Same local anaesthesia approach. |
| Recovery time | Similar for both; many patients see well within 24–48 hours. | Similar short-term recovery. |
Both forms of LASIK then use the same excimer laser to reshape the cornea. The key advantage of bladeless LASIK is the improved precision and consistency of the flap, which sets up the second step for better results.
How the Femto LASIK Procedure Works Step by Step
Before we perform any procedures in the operating room, we do an in-depth pre-op evaluation of the patient. We do corneal topography and tomography scans, measure the size of the pupils, screen for dry eye, and check binocular vision. This workup is to determine if you are a good candidate for LASIK.
On the day of the procedure:
The eye is anesthetized with drops. No injections are required. A gentle suction ring, which holds the eye still, is used while the femtosecond laser creates the corneal flap in about 15 to 20 seconds. The flap is made, then pushed back, and the excimer laser which custom shapes the corneal surface according to your exact prescription, usually in under 30 seconds. The flap is put back in place and bonds back together without stitches. The total process for both eyes usually takes under 15 minutes.
Most patients report large improvements in vision the same day of the procedure, or the very next morning. Vision will continue to improve over the first week.
Is Bladeless LASIK Surgery Painful?
In every pre-op consultation, this is the question we get the most.Patients expect to leave feeling pain, which they don’t. Anesthesia works very well. During the femtosecond laser phase, you may feel mild pressure from the suction ring not pain, but awareness. The excimer laser which does the reshaping is totally comfortable.
Post-procedure, mild irritation, watering, and light sensitivity for a few hours is what you will see and that which we will sort out with rest and the given drops. The days after the procedure went well. In the first week, you may have slight dryness or fluctuating vision which is normal as the cornea heals.
Who Is a Good Candidate for Bladeless LASIK?
Not all patients are fit for LASIK, bladeless or otherwise. At a good LASIK center we do a thorough evaluation.
Also, in most cases, we find that suitable candidates are those who:
- Over 18 years of age, with stable prescriptions for at least a year.
- Have sufficient corneal thickness for safe flap creation and tissue removal.
- Do not have active dry eye disease, keratoconus, or any other eye conditions.
- To have an error that the laser system we use can correct.
People who have very thin corneas, irregular corneal shape, or very high prescriptions may do better with alternative procedures like SMILE or phakic IOL implantation. This is to say that at a qualified eye hospital, pre-operative screening is of great importance as it is the procedure itself.
LASIK Surgery Cost and What to Expect
Preoperative scans, the procedure, prescribed drops, post op follow up visits, and whether there is an enhancement option. A lower reported number which excludes pre op tests and follow up visits may not be the better deal.
LASIK Care at Vasan Eye Care
At Vasan Eye Care, we perform bladeless Femto LASIK which is accompanied by an in-depth pre-op workup that includes corneal mapping, dry eye assessment, and what treatment will be best for each patient’s individual case before we do anything. We go over all options which include standard LASIK, bladeless LASIK, Contoura Vision, and SMILE and we give our patients all the info they need about what will work best for their eyes and their prescription. Post-op care includes a set follow-up at Day 1, Week 1, and the 1-month mark. which also includes extended monitoring for patients with high prescriptions or dry eye issues.
Key Takeaways
Bladeless LASIK uses a femtosecond laser instead of a mechanical blade for creating the corneal flap, which, in turn, makes the first step of the procedure more precise and predictable.
As for the second step, which is corneal reshaping that still uses the same excimer laser in both bladeless and traditional LASIK.
What bladeless does have going for it is that it provides better flap consistency and a lower risk of flap-related complications.
Also, the procedure is done under topical anesthesia which is comfortable for the patient, it takes under 15 minutes for both eyes and most patients see great improvement in vision within 24 to 48 hours.
Not everyone is a candidate for it; it is important that proper screening is done at a qualified LASIK center before any decision is made.
Frequently Asked Questions
They are the same thing. What we know as “Femto LASIK” and “bladeless LASIK” in fact are just different names for the same procedure, which is the use of a femtosecond laser to create the corneal flap as opposed to a mechanical blade. Some centers go with one term, some with the other. In either case the flap is created with laser precision which is then used to reshape the cornea.
Taylor Swift has reported that she had LASIK, which she underwent for vision correction. She spoke of it very positively in interviews she says she doesn’t wear glasses post procedure. The type of LASIK she had is still not officially confirmed but her results are like many other patients’ which see laser vision correction as a great quality of life improvement.
Femto LASIK is painless. Anesthetics in the form of drops put the eye to sleep before they begin. During the femtosecond laser which is a part of the procedure you may feel a very mild pressure from the vacuum device that holds the eye steady which is short and not painful at all. After the procedure which may leave you with some mild discomfort, watering and light sensitivity for a few hours most people do better with it then they think they will.
Most present LASIK devices which we have seen to safely correct myopia up to an average of -10.00 to -12.00 dioptres, hyperopia up to around +5.00 to +6.00 dioptres, and astigmatism up to about 5.00 to 6.00 dioptres which in turn is based on corneal thickness and the specific laser machine used. For cases going beyond these ranges, or when corneal thickness is an issue, options like phakic IOL implantation or refractive lens exchange may be put forth. At your pre op evaluation at the LASIK center you will get a for sure answer based on your own corneal data and prescription.
